I work in a children's hospital and how we describe lackluster growth of young humans is "Failure to Thrive". We can all acknowledge this is not a nice term for parents to hear, so there is a push to move to the term "Growth Faltering". Which, IMO, is frankly not much nicer... Sometimes you just have to use negative words to describe a negative outcome.
@@TiffanyL50 Fully agree. Dated medical jargon is a lot like date scientific jargon. It is hard to eradicate long used diagnoses/terms or switch to verbiage that is less likely to hurt and offend. I walk into every room of a child not growing well and explain to parents this does not mean they are a failure as a parent. I do think in person most medical staff and physicians refer to the child as "not growing well", but often in charts the listed diagnosis remains "Failure to Thrive".

@@djc6323so you think humans have evolved in spite of using "dangerous" blankets forever? Don't be ridiculous. If You need a blanket to sleep, why do you think your baby doesn't?! I can't stand some of these new 'rules' some parents follow. It's like people's brains go right out of the window, because the so called experts say so!
I don't understand this point though, because it goes against natural climate? In almost all cases outdoor day time temps are higher than night temps, surely to mimic that you would keep it the same?
So what I’ve noticed is heat makes a huge difference in growth. Learned that growing non-stop begonias. They wouldn’t budge until I increased the heat. This year I started peppers Way too early and slowed them down by getting them out to a cooler greenhouse. I never use fertilizer as there is enough in the potting mix. I use 12 hours of light morning to night as onions are particularly sensitive to day length. I start indoors and they move out to greenhouse once our temps warm enough to heat the greenhouse. Most flowers are started in germination trays then potted up, but vegetables get their own cell packs. I think two of the biggest problems many have is starting Way too early and overwatering and partly to do with not enough perlite in heavy soil. Sufficient lighting is another. For hardening off I recently potted up some veg (peppers, eggplants, tomatoes) and flowers and they have been doing fine under a glass patio table on a raised deck with nights in mid 40s F. The greenhouse is full😂 and more still going out so sink or swim. Most of the peppers are out in the GH or already transplanted under a frost covered tunnel. The tomatoes are still mainly in the house as I was disciplined enough to start them at just the right time this year so they can go from root prune 4 cell packs to garden and no potting up. We plant out normally by end of May with last frost date 5/12-Z5a, WI. About giving plants darkness-a break- is true. One year I wondered why some annuals didn’t flower and realized they were under our yard light that stays on all night.

@@GardeningInCanada Mine would be too, I drag garbage cans full of this crap down into the basement, kinda getting to old for that, lol. For sure not everyone can go the all natural route. Question! What to start a bokashi bin. I make batches of LAB, is that enough, or do I need to add yeast? I will look to see if you have a bokashi video. You certainly grow some outstanding seedlings. Have a good weekend!!!!
I ❤ your mind. Doesn't think I'd be into the research behind plant growth but I keep reviewing this video to figure out what I may be doing wrong with seedlings. My green thumbs only seem to work when I buy plants but i really want to grow my own. thank you for great info.
My best growth was when I placed my seedlings on top of electric blanket, hung lights over them, and added some wind by recycling an old computer fan. I had an old DC power plug so I connected those wires to computer fan wires and added a plug from some toy. This provided a very gentle wind when seedlings started to have their 2nd leaves. This improved air circulation and strengthened the stems. You could barely see them move, but it did make a difference. The heat blanket made my tomatoes sprout in 3 days! My tomatoes were 16 inches tall in 1 month! They were too big when I did it the first time and I didn't expect such growth, but the weather outside was just not ready for them.
Thank you for sharing your wisdom so fully, what an amazing channel ❤ I'm Gardening in South Africa🇿🇦 so we heading into Spring so right now I am particularly enjoying your earlier videos and videos on mulching and seedlings, I'm a big fan of your Gardening in Canada 🇨🇦 channel keep up the great work⭐⭐⭐
I used that fertilizer for the first time this year and it has made a huge difference. I don't know if it is species specific, but I was fertilizing everything in the greenhouse and absent-mindedly did my honey locust trees. I had not intended to, since finding info for locust tree seedings has been a challenge. They were started from seed mid March and were doing well in a potting soil, but after the promix root fertilizer, they need the big pots so they don't girdle themselves and they are a foot tall. They are part of the legume family but are not nitrogen fixing, so maybe that had something to do with it? I am so pleased with them and it's so cute how they fold their little leaves up at night. Thanks to your videos, I have had the most successful year yet with my plants!
I’m going to try the warmer temps at night for my tomatoes….it totally makes sense because as soon as the outdoor nighttime temps increase my tomatoes always take off and grow like crazy. I’m in MB; nothing is in the garden yet. Thanks for this! 😊❤
Going to look into that probe... I like tech but more importantly I like when things can communicate. My houseplants get droopy, my kids yell, even the cat has learned to get underfoot when she needs something. My seedlings don't talk. They got left outside about a month ago and cucumbers didn't survive. Would have been nice to get that alert when temps were dropping "hey we're freezing out here"
I am confused. Was the seedling that didn't do as well started in a different location? If so where and under what conditions? You might have explained it in your video but I couldn't find it. BTW, I love your videos especially that you explain the science behind what you are saying. The nerdy videos might not get as many clicks but I think they are the reason for your diehard followers. (Plus the fact that you are a real person living in the real world which makes it easy to relate to you.) Thank you for being you!
@@GardeningInCanada yeah I usually in third in line in terms of receiving people's seedling leftovers but it's a fairly good arrangement (ended up with 80 pepper and 15 tomato seedlings last year and only lost one pepper!) so I don't have anything really yet except for what grew in my indoor worm isopod springtail moss compost tank thing in my house. I tossed in some seeds I'd saved from what I grew last year and random things grow occasionally so I just took them out but they're small since I forgot 😆
Dang! Great info... drinking from a fire hose but that is awesome. I wish I saw this a month ago. Here in Southern New Hampshire I still have time to put some of this great info to work!
The Pro Mix 5-15-5 isn't available here in the US. So, I've done the math for the proportions of combining the Miracle-Gro General Purpose, Tomato, and Bloom fertilizers to get that 5-15-5 ratio. Should that also work for seedlings or are there other things in the Pro Mix that would not be in the Miracle-Gro? Thanks.
Love your videos. Love the sciencey-wiencey/wienciness of your videos. (Sorry... Dr. Who reference). You and another UA-camr are the only ones, for gardening, I'm subscribed to. Found you a year ago when I started growing from seed. I am also in Canada (Toronto) and find your information invaluable. Would like some advice... Been having trouble with my tomato seedlings. They are now 3 feet tall and the stems are very thin. They are definitely leggy and seen to have been from the start. They are trellised up in my kitchen at this moment. Nights are, I believe, still to cool to transplant out
Is it harder to acclimate the seedlings for outside conditions after they are controlled so much in the beginning? Great video BTW 😄 I always appreciate the knowledge you share.
Oh, those 16 to 18 hour days in the field... I certainly don't miss that from my Land Rec days! As always, thanks for the advice! I'm stupid late starting my plants this year, so these tips should help me out a lot!
I stick my lights on TPLink KASA. They have a sunrise/sunset option for their automation based on your location. You would need wifi extending to your GH though, which I assume you have with the earthone.
Really enjoyed this one. Puget Sound here in the cloudy wet PNW. I’ve only had my greenhouse up and running a couple years and the light and temperature has always been a mystery to me. So many different opinions online. I’d rather go with science. The first few flats I started grew tremendously. Vigorous tomatoes with strong ‘bones’. but the second ones I planted two weeks later did not. I’ll have a whole year to research the day/ night temps and light. Thank you for giving me a good direction to go.
During the winter in my indoor grow room with the vent closed and all my grow lights on, everything grew super fast. VPD was on the daily. Now that I’ve started some late peppers, some pumpkins and zinnias, with no unnecessary lights on, it’s much slower growing. Probably only 73° F the whole time. I agree on the phosphorus for seedlings…because, I’ve seen it work 😊 But, 😅 I was thinking maybe longer hours of light might help. Thanks for the info on that!
Hi Ashley! Love all your videos! When you got to talking about fertilizers and brought out the Pro Mix root booster, I was so happy because that's all I use! That stuff is amazing and I always recommend it! Thank you for sharing your knowledge! Much appreciated!
I just planted my seedlings in the garden today and they are a sorry looking bunch. Obviously my fault and this video will help me do better next year. Thanks!
I read a research paper from the University of Georgia in the US. For tomatoes, he recommended using Miracle Gro for tomatoes until they begin flowering. He then recommended changing to Miracle Gro bloom booster which is higher in phosphorus.
Completely agree that the environmental variables are by far the most important for the best results. I use a IR temperature gun to check leaf temperatures for VPD, the lower leaf temperature tells you there is active transpiration. The phos study sounds interesting, i`ll have to do some side by side testing.
i think positive differential is lower temps during night, and higher temps during the day. better to not allow more than 10 degrees difference, if 6 being optimal in some cases. double check and let me know (when it comes to the definition for positive differential).
Trying to make sure I understand. Is the temperature differential to be concerned about the ambient (air) temp or soil temp? For example, If I recreate in my house, should I be upping the thermostat at night or growing my seedlings off of the heat mat during the day and on the heat mat overnight? Apologies if I missed the distinction in the vid. I've watched twice so far to check my understanding.
Thank you for this video, and your past feedback. Thank you for sharing your knowledge. I'm using Organican, it's 2-5-2. I have a little greenhouse, and I use a heater and a large fan. I run the fan day and night at different feeds. I have nice thick stems, and always thought it was due to the fan (I also turn and move plants almost daily). I start my seedlings in the in a grown box/tent zippered frame with a grow light that I turn off at night. I started putting out seedling during the day (tomatoes) to start hardening them off, but is it too soon here in Manitoba? Should I still keep the greenhouse temps up during the day? Also, I had a terrible time with peppers not germinating this year, can I let those now coming up still try and keep them in the greenhouse all summer, or can they still be planted outside in June? Take care and thank you and all the commenters. Hi, from the Manitoba Interlake (I'm south of Gimli)
Hello GardeningInCanada! Idk if you’re still answering questions on this video, but I had one about the day/night cycle. I like to run my grow lights overnight since electricity is a little cheaper then. So when it’s time to harden off and move them outside… could they get “jet lagged”? 😅
Great science based video. Higher temps at night! What a game changer. I've long thought that longer stems, stretching, was undesirable. You want stocky strong plants, not tall spindly ones. I assume that I am misunderstanding the study. I assume that the taller plants also had more biomass, leaves, nodes, etc. up the longer stem.
I accidentally did the positive heat thing with some seeds. I started all the seed packs I had (except the biennials) and the second flat had basil, dahlias, and other tender things. I put them out for the 12 degree days and brought them in for the night in the warm house. I was nervous that that change was harming them but I could not leave them outside for the overnight lows. I was surprised what grew. I have a dahlia from some pretty old seed. It is nice to know it is a Good Thing! 😉
Well educated, love all your informative videos everything gardening! Thank you for sharing. I use pro mix fertilizer with my seedlings once a month feed as i used pro mix soil with mycroniza and other nutrients this past winter season now everything all outside. Can you use pro mix fertilizer outside once a month as well on all tomoatoes, veg flowers too? I know you mentioned inside seedlings but what about a boost once outside the season so short. Thank you.
Temeprature, light and water regiment were key for me to reduce waiting time to get true leaves on cotyledon plants that produce true leaves after another season. I have been experimenting for years until I figured out the ultimate settings. Now I'm experimenting with hormones. But that's a whole other story...
VPD question (apologies if it's already been answered). All the charts/studies I can find are for marijuana plants. I know you said just look at the "vegetative" numbers... Would this also apply to the indoor aroid world?
I have three tomato plants I planted from seed outside and they’re 3 different sizes. One is huge and the smallest one is tiny like the one you showed. Crazy
@@psynurse over time you read the leaves and the plant itself to see what it needs. For instance there is a slight wilt when some if them need water, if the leaves droopy it's too much light or too much water typically. All plants are different it's basically just experience
Ashley, I just up-potted my tomatoes with a generous helping of granular miracle-gro 10-5-15. Do you think I should add extra phosphorus to them? How would I add it?
Just leave them it will be fine. You could (if you wanted to) just give them an extra bump when you plant them outside. But you likely won’t notice a massive difference
My seedlings burnt in the sun :C The greenhouse I used was in a south-facing direction and I was hardening them off, but I had a particularly hot morning that totally scorched all the seedlings in it. :'c Peppers are okay, I wound up just buying some from a local garden market, potted them up & now I'm harvesting some fresh radishes!
I wish i had an alert for my phone. Some of the colds nights i went out to check a few times. I had to rig up tarps and make the area smaller to heat. I like to start things like panseys and snap dragons early.
Question: How, if at all, would any of this be different for rooting cuttings? I am often rooting cuttings of things like figs, mulberries, pomegranates and olives after winter pruning. (Yeah, I live in SoCal, not anywhere in Canada!)
If a person lived in the high desert in the SW United States, would window light likely be sufficient, as long as the soil is warm? Or do you recommend lights even there?
QUESTION: Is there any significance to Temp Diff when you're looking at trays of seeds, not yet seedlings? Right now I'm just running a 20W pad under a tray 24×7 in ambient indoors.
You're channel is very informative! Thank you for sharing all your knowledge 😊 I am new to gardening and totally confused with fertilizers, some of them say organic and some don't. I have little children and I am always worried about using the non-organic fertilizers. Would you know if the Promix Root Booster is organic? You're assistance would be greatly appreciated 😊
Not organic. But don’t stress about the organic vs. Non-organic it’s safe. It’s all the same stuff. Plants can only take up nutrients in specific forms.
Oooooooooo... you are soooooooo wrong my dearest redheaded angel... I trust your advice very much ~ in the garden.. & I'm sure I am not the only one who appreciates your honesty about life recently... Ya is Definitely an angel in my books.. 🤗🤗 Or a wonderful garden fairy godmother .. 🧚♀️ ❤
Ashley, The link for the Promix Fertilizer was not the Root Booster 5-15-5 you showed that you use. Would you send the link to the Promix Root Booster version that you use?
But energy consumption is the problem. Because when I pay for heating I could as well pay for vegetables being transportet to me from a warmer part of the globe...
Well they are actually from local produce greenhouses that very likely are heated, lit, have co2 pumps etc. but something this small could easily go on solar power
In Ontario Canada, we have a choice of a hydro tiered system where Hydro rates are lower at night. So heating a greenhouse or grow room at night is optimal with heat from sun during the day.
Not sure if it was this video that you mentioned using ProMix 5-15-5 for your seedlings every time you water, but I was wondering if you use it full or 1/2 strength on your seedlings?
The early spring light in my in-ground garden turned out to be so bad I was seriously considering rigging mirrors around. A starting area and lights is probably a better idea xD There was a lot of really actionable info in this one. I'm going to have to watch a few more times. But I got a spark with the daylight tracking bit.
@@GardeningInCanada Yeah, I have a N-S garden with a cherry tree on the SE half and a garage on the NW half of my row. So in the start of spring it wasn't even getting direct light until 1ish and was still getting dark by like 5. It'll be good at least until fall now. I just need to check how that light falls too and then plan for trays. Planted 3rd week of march and most things didn't germinate, and then what did didn't move past 1in until may xD. It was also just a very cold and mucky spring with night temps nearing freezing. I started tomatoes in the windows and porch on the other side of the house and those did pretty well. So I'll just need to expand on that in following cycles. I went from a 3x3 last year to a 2.5x18 one this year and was looking at late summer light patterns when I planned that. I underestimated haha.
She might be able to get away with it since the limit is the heat dissipation from the wire gauge inside the controller.. which will be cold when running at 1500W. But insurance probably wouldn't pay if they find that anywhere near a fire.
@@GardeningInCanada no product in mind at this time, but I am trying to go all organic with mostly Tropicals in the desert of AZ. I am just curious about those because I was going down the rabbit hole one day.
So with temp, let's say I'm starting some tomatoes and I have a heat pad for germination. The info I've had is that I should turn off the pad after sprouting. I don't have a thermometer or anything, just stable inside temp of around 21, would you suggest just keeping the heat pad on all the way until planting out? If so what temp would you set it to? Love your vids.
A little confused... Thank you for this fantastic info. I am behind on my starts this year, seems like there still could be hope. I am in NY, USDA zone 5B. I do my starts indoors on heating mats and would love for the community to help me check my understanding. Is it 30 degrees C during the day and 20 degrees C at night? Should I follow the same 12 hour and 12 hour approach for heat? How long do I keep the heat up for? Days? Weeks? If I elevate the plants above the heating mats once they germinate will that work for heating or should I switch to a heater? Thanks
Given the grow lights produce heat, you didn’t explain how you get higher temperatures at night. Are you using two different heaters on timers with different set points?
Great stuff thanks. I’m in Australia growing native plants a lot. They are adapted to low phosphorus soils. Apparently. Do you have fertiliser suggestions or comments?

@@GardeningInCanada Mine would be too, I drag garbage cans full of this crap down into the basement, kinda getting to old for that, lol.
For sure not everyone can go the all natural route.
Question! What to start a bokashi bin. I make batches of LAB, is that enough, or do I need to add yeast? I will look to see if you have a bokashi video.
You certainly grow some outstanding seedlings. Have a good weekend!!!!
2:33 “Ginger with a halo 😇 that’s not real” 😂😂😂😂😂😂😂😂
You are so awesome! I enjoy your presentation style so much, and tons of awesome of info
I ❤ your mind. Doesn't think I'd be into the research behind plant growth but I keep reviewing this video to figure out what I may be doing wrong with seedlings. My green thumbs only seem to work when I buy plants but i really want to grow my own. thank you for great info.
Whats your take on sunrise sunset cycle lighting vs timed on/off lighting? Do plants grow better under simulated dawn to dusk?
My best growth was when I placed my seedlings on top of electric blanket, hung lights over them, and added some wind by recycling an old computer fan. I had an old DC power plug so I connected those wires to computer fan wires and added a plug from some toy. This provided a very gentle wind when seedlings started to have their 2nd leaves. This improved air circulation and strengthened the stems. You could barely see them move, but it did make a difference. The heat blanket made my tomatoes sprout in 3 days! My tomatoes were 16 inches tall in 1 month! They were too big when I did it the first time and I didn't expect such growth, but the weather outside was just not ready for them.
Thanks for explaining the temperature differential. Not sure how I got that so complicated for myself. 😂
Thank you for sharing your wisdom so fully, what an amazing channel ❤ I'm Gardening in South Africa🇿🇦 so we heading into Spring so right now I am particularly enjoying your earlier videos and videos on mulching and seedlings, I'm a big fan of your Gardening in Canada 🇨🇦 channel keep up the great work⭐⭐⭐
Have fun!
I used that fertilizer for the first time this year and it has made a huge difference. I don't know if it is species specific, but I was fertilizing everything in the greenhouse and absent-mindedly did my honey locust trees. I had not intended to, since finding info for locust tree seedings has been a challenge. They were started from seed mid March and were doing well in a potting soil, but after the promix root fertilizer, they need the big pots so they don't girdle themselves and they are a foot tall. They are part of the legume family but are not nitrogen fixing, so maybe that had something to do with it? I am so pleased with them and it's so cute how they fold their little leaves up at night. Thanks to your videos, I have had the most successful year yet with my plants!
This is next level info! As I prepare to get started on this season’s seed-starting, I am so happy to find your channel.
This is the single best gardening video ever!
Jeeze thank you 🙏 that’s big praise
What's your thoughts on 14-16 hrs light on seedlings when germinating and early growth.
There is lots who do that! And to be honest now the days are longer I’m most definitely over 12 the big thing is dark is dark.
@@GardeningInCanada Thanx, channel's great. Like I'm back in Bio lab, well supposed to be.
I’m going to try the warmer temps at night for my tomatoes….it totally makes sense because as soon as the outdoor nighttime temps increase my tomatoes always take off and grow like crazy. I’m in MB; nothing is in the garden yet. Thanks for this! 😊❤
Perfect! I’m waiting till June
Going to look into that probe... I like tech but more importantly I like when things can communicate. My houseplants get droopy, my kids yell, even the cat has learned to get underfoot when she needs something. My seedlings don't talk. They got left outside about a month ago and cucumbers didn't survive. Would have been nice to get that alert when temps were dropping "hey we're freezing out here"
Ahahaha how true is that 😂
I am confused. Was the seedling that didn't do as well started in a different location? If so where and under what conditions? You might have explained it in your video but I couldn't find it. BTW, I love your videos especially that you explain the science behind what you are saying. The nerdy videos might not get as many clicks but I think they are the reason for your diehard followers. (Plus the fact that you are a real person living in the real world which makes it easy to relate to you.) Thank you for being you!
i love the research backed conclusions! more of this please!
You have answered the questions that I was JUST thinking about a couple of hours ago. HOW!?? THANK YOU AGAIN 🎉❤
Hahah awe. Are your plants behind ?
@@GardeningInCanada yeah I usually in third in line in terms of receiving people's seedling leftovers but it's a fairly good arrangement (ended up with 80 pepper and 15 tomato seedlings last year and only lost one pepper!) so I don't have anything really yet except for what grew in my indoor worm isopod springtail moss compost tank thing in my house. I tossed in some seeds I'd saved from what I grew last year and random things grow occasionally so I just took them out but they're small since I forgot 😆
You've become my favorite gardening channel.
Wow, thank you! 🙏
Dang! Great info... drinking from a fire hose but that is awesome. I wish I saw this a month ago. Here in Southern New Hampshire I still have time to put some of this great info to work!
The beauty of gardens it’s an endless cycle 😆
The Pro Mix 5-15-5 isn't available here in the US. So, I've done the math for the proportions of combining the Miracle-Gro General Purpose, Tomato, and Bloom fertilizers to get that 5-15-5 ratio. Should that also work for seedlings or are there other things in the Pro Mix that would not be in the Miracle-Gro? Thanks.
Love your videos. Love the sciencey-wiencey/wienciness of your videos. (Sorry... Dr. Who reference). You and another UA-camr are the only ones, for gardening, I'm subscribed to. Found you a year ago when I started growing from seed. I am also in Canada (Toronto) and find your information invaluable. Would like some advice... Been having trouble with my tomato seedlings. They are now 3 feet tall and the stems are very thin. They are definitely leggy and seen to have been from the start. They are trellised up in my kitchen at this moment. Nights are, I believe, still to cool to transplant out
Is it harder to acclimate the seedlings for outside conditions after they are controlled so much in the beginning?
Great video BTW 😄 I always appreciate the knowledge you share.
I don’t have issues but I harden my plants off in the most bizarre way 😅
@@GardeningInCanadatell us what is that bizarre way!?
Great information; thanks for sharing! Have a great growing season all 🤗🇨🇦
YOU TO!
My wavelink on gardening. I’m staying tuned. Thanks for sharing
Oh, those 16 to 18 hour days in the field... I certainly don't miss that from my Land Rec days!
As always, thanks for the advice! I'm stupid late starting my plants this year, so these tips should help me out a lot!
I stick my lights on TPLink KASA. They have a sunrise/sunset option for their automation based on your location. You would need wifi extending to your GH though, which I assume you have with the earthone.
😲😲😲 that is so cool!!!!!!
I literally no idea that that was a thing
That sounds cool
Really enjoyed this one. Puget Sound here in the cloudy wet PNW. I’ve only had my greenhouse up and running a couple years and the light and temperature has always been a mystery to me. So many different opinions online. I’d rather go with science. The first few flats I started grew tremendously. Vigorous tomatoes with strong ‘bones’. but the second ones I planted two weeks later did not. I’ll have a whole year to research the day/ night temps and light. Thank you for giving me a good direction to go.
During the winter in my indoor grow room with the vent closed and all my grow lights on, everything grew super fast. VPD was on the daily. Now that I’ve started some late peppers, some pumpkins and zinnias, with no unnecessary lights on, it’s much slower growing. Probably only 73° F the whole time. I agree on the phosphorus for seedlings…because, I’ve seen it work 😊
But, 😅 I was thinking maybe longer hours of light might help. Thanks for the info on that!
Hi Ashley! Love all your videos! When you got to talking about fertilizers and brought out the Pro Mix root booster, I was so happy because that's all I use! That stuff is amazing and I always recommend it! Thank you for sharing your knowledge! Much appreciated!
I use peat+composted manure+perlite. Should I also fertilize every time i water? Should I use a low ec and water until runoff?
I just planted my seedlings in the garden today and they are a sorry looking bunch. Obviously my fault and this video will help me do better next year. Thanks!
I read a research paper from the University of Georgia in the US. For tomatoes, he recommended using Miracle Gro for tomatoes until they begin flowering. He then recommended changing to Miracle Gro bloom booster which is higher in phosphorus.
Completely agree that the environmental variables are by far the most important for the best results. I use a IR temperature gun to check leaf temperatures for VPD, the lower leaf temperature tells you there is active transpiration. The phos study sounds interesting, i`ll have to do some side by side testing.
id have to agree with your fertalizer choice, i use 3/6/12 and my seeds blow up quickly, lots of root quick.
It’s amazing right!
i think positive differential is lower temps during night, and higher temps during the day. better to not allow more than 10 degrees difference, if 6 being optimal in some cases. double check and let me know (when it comes to the definition for positive differential).
Trying to make sure I understand. Is the temperature differential to be concerned about the ambient (air) temp or soil temp? For example, If I recreate in my house, should I be upping the thermostat at night or growing my seedlings off of the heat mat during the day and on the heat mat overnight? Apologies if I missed the distinction in the vid. I've watched twice so far to check my understanding.
Thank you for this video, and your past feedback.
Thank you for sharing your knowledge.
I'm using Organican, it's 2-5-2. I have a little greenhouse, and I use a heater and a large fan.
I run the fan day and night at different feeds. I have nice thick stems, and always thought it was due to the fan (I also turn and move plants almost daily).
I start my seedlings in the in a grown box/tent zippered frame with a grow light that I turn off at night.
I started putting out seedling during the day (tomatoes) to start hardening them off, but is it too soon here in Manitoba? Should I still keep the greenhouse temps up during the day?
Also, I had a terrible time with peppers not germinating this year, can I let those now coming up still try and keep them in the greenhouse all summer, or can they still be planted outside in June?
Take care and thank you and all the commenters.
Hi, from the Manitoba Interlake (I'm south of Gimli)
Hello GardeningInCanada! Idk if you’re still answering questions on this video, but I had one about the day/night cycle. I like to run my grow lights overnight since electricity is a little cheaper then. So when it’s time to harden off and move them outside… could they get “jet lagged”? 😅
Great science based video. Higher temps at night! What a game changer. I've long thought that longer stems, stretching, was undesirable. You want stocky strong plants, not tall spindly ones. I assume that I am misunderstanding the study. I assume that the taller plants also had more biomass, leaves, nodes, etc. up the longer stem.
Tall doesn’t always translate to spindly or weak. Tall in the world of tomatoes can mean proper airflow, good light capture, etc.
I accidentally did the positive heat thing with some seeds. I started all the seed packs I had (except the biennials) and the second flat had basil, dahlias, and other tender things. I put them out for the 12 degree days and brought them in for the night in the warm house. I was nervous that that change was harming them but I could not leave them outside for the overnight lows. I was surprised what grew. I have a dahlia from some pretty old seed. It is nice to know it is a Good Thing! 😉
That’s awesome! Good job
@@GardeningInCanada Thank you. I am learning! ☺️
Well educated, love all your informative videos everything gardening! Thank you for sharing. I use pro mix fertilizer with my seedlings once a month feed as i used pro mix soil with mycroniza and other nutrients this past winter season now everything all outside. Can you use pro mix fertilizer outside once a month as well on all tomoatoes, veg flowers too? I know you mentioned inside seedlings but what about a boost once outside the season so short. Thank you.
Congratulations again ! ❤ love seeing u do what u love ! Thank u for the video ❤
Thank you so much!!
So how do you rescue those little plants?
My plants are always tiny and I could really use a simple solution to help the ones I have grow bigger.
Do cooler days and warmer nights
Temeprature, light and water regiment were key for me to reduce waiting time to get true leaves on cotyledon plants that produce true leaves after another season. I have been experimenting for years until I figured out the ultimate settings.
Now I'm experimenting with hormones. But that's a whole other story...
Thank you so much for this information!!! Definitely helped me see where I can improve with my seedling.
Great to hear!
What do you all have planted this year?
VPD question (apologies if it's already been answered). All the charts/studies I can find are for marijuana plants. I know you said just look at the "vegetative" numbers... Would this also apply to the indoor aroid world?
110% it would. Just use the cannabis one they are pretty well all close to eachother. VPD is all plants
I have three tomato plants I planted from seed outside and they’re 3 different sizes. One is huge and the smallest one is tiny like the one you showed. Crazy
Do you water the whole tray from the bottom or just the plants that need it from the top
Just top watering once they are at this stage
Good video 😊key is harding off as good as you care for seedlings
Thanks so much for the info. I am a 🇨🇦 gardener too. There is much difference in your plants 😀
You are so welcome!
Link for soil for hanging baskets?
Mondays video!
76 to 79f and 60 humidity is the best from my testing. My ladies love it😊
Better light is my guess, yep temps too especially for germination. Cold temps slow them down a ton. I like to read plants not use devices
What is reading plants?
@@psynurse over time you read the leaves and the plant itself to see what it needs. For instance there is a slight wilt when some if them need water, if the leaves droopy it's too much light or too much water typically. All plants are different it's basically just experience
That’s fair
What is the best way to grow poppies?
Ashley, I just up-potted my tomatoes with a generous helping of granular miracle-gro 10-5-15. Do you think I should add extra phosphorus to them? How would I add it?
Just leave them it will be fine. You could (if you wanted to) just give them an extra bump when you plant them outside. But you likely won’t notice a massive difference
My seedlings burnt in the sun :C
The greenhouse I used was in a south-facing direction and I was hardening them off, but I had a particularly hot morning that totally scorched all the seedlings in it. :'c
Peppers are okay, I wound up just buying some from a local garden market, potted them up & now I'm harvesting some fresh radishes!
Omph yes! That can happen
I wish i had an alert for my phone. Some of the colds nights i went out to check a few times. I had to rig up tarps and make the area smaller to heat. I like to start things like panseys and snap dragons early.
Oh yes. Sometime I have to do wild stuff as well. Dang cold nights
Ashley, if you use it every time you water, how much of that root booster do you add per gallon/L?
I go to the number one on the cap. And yea everytime
@@GardeningInCanada is it per gallon or litre?
Question: How, if at all, would any of this be different for rooting cuttings? I am often rooting cuttings of things like figs, mulberries, pomegranates and olives after winter pruning. (Yeah, I live in SoCal, not anywhere in Canada!)
If a person lived in the high desert in the SW United States, would window light likely be sufficient, as long as the soil is warm? Or do you recommend lights even there?
QUESTION: Is there any significance to Temp Diff when you're looking at trays of seeds, not yet seedlings?
Right now I'm just running a 20W pad under a tray 24×7 in ambient indoors.
Zero, constant temp is accurate what is important for seeds.
You're channel is very informative! Thank you for sharing all your knowledge 😊 I am new to gardening and totally confused with fertilizers, some of them say organic and some don't. I have little children and I am always worried about using the non-organic fertilizers. Would you know if the Promix Root Booster is organic? You're assistance would be greatly appreciated 😊
Not organic. But don’t stress about the organic vs. Non-organic it’s safe. It’s all the same stuff. Plants can only take up nutrients in specific forms.
Oooooooooo... you are soooooooo wrong my dearest redheaded angel...
I trust your advice very much ~ in the garden.. & I'm sure I am not the only one who appreciates your honesty about life recently...
Ya is Definitely an angel in my books.. 🤗🤗
Or a wonderful garden fairy godmother .. 🧚♀️ ❤
Thank you so much for your response, that is reassuring 😊
You are so welcome!
OK! So if you are seeking a long thick stem then you need to bring on the night heat!
Yuppers!!!
Ashley, The link for the Promix Fertilizer was not the Root Booster 5-15-5 you showed that you use. Would you send the link to the Promix Root Booster version that you use?
Oh what the heck. Are you in the US?
Yes, I’m in the US
But energy consumption is the problem. Because when I pay for heating I could as well pay for vegetables being transportet to me from a warmer part of the globe...
Well they are actually from local produce greenhouses that very likely are heated, lit, have co2 pumps etc. but something this small could easily go on solar power
In Ontario Canada, we have a choice of a hydro tiered system where Hydro rates are lower at night. So heating a greenhouse or grow room at night is optimal with heat from sun during the day.
Would a heat mat under the plants work?
Not sure if it was this video that you mentioned using ProMix 5-15-5 for your seedlings every time you water, but I was wondering if you use it full or 1/2 strength on your seedlings?
Thanks for he ferilizer tip.
Any time!
The early spring light in my in-ground garden turned out to be so bad I was seriously considering rigging mirrors around. A starting area and lights is probably a better idea xD
There was a lot of really actionable info in this one. I'm going to have to watch a few more times. But I got a spark with the daylight tracking bit.
Are you pretty shaded?
@@GardeningInCanada Yeah, I have a N-S garden with a cherry tree on the SE half and a garage on the NW half of my row. So in the start of spring it wasn't even getting direct light until 1ish and was still getting dark by like 5. It'll be good at least until fall now. I just need to check how that light falls too and then plan for trays. Planted 3rd week of march and most things didn't germinate, and then what did didn't move past 1in until may xD. It was also just a very cold and mucky spring with night temps nearing freezing.
I started tomatoes in the windows and porch on the other side of the house and those did pretty well. So I'll just need to expand on that in following cycles. I went from a 3x3 last year to a 2.5x18 one this year and was looking at late summer light patterns when I planned that. I underestimated haha.
Ok, I will follow your ways next year. This year is lost for my seedlings... Greetings from nortthern Poland! Last frost wss yesterday 😉
Thanks
Is the story similar for cuttings? Been looking pretty longingly at these pencil-like fruit and berry cuttings for a while now.
Thank you for this! 😊
You're so welcome!
I may have missed in a previous video but what kind of greenhouse do you have?
I have it linked in this video ua-cam.com/video/SFm_rz-Ge8c/v-deo.htmlsi=mTs4JB24vZ8iUV4n
Hi, won't you short circuit your Inkbird Temperature Controller since it is only 1100W and your Utilitech heater is 1500-Watt?
She might be able to get away with it since the limit is the heat dissipation from the wire gauge inside the controller.. which will be cold when running at 1500W. But insurance probably wouldn't pay if they find that anywhere near a fire.
Pffft ummm 🤔 this is good to know 😅
The heater method is really interesting, sadly energy prices are 4x higher here than in canada
Do you have any recommendations or insights on inoculation of plants or soil with pseudomonas or Bacillus?
Are you using a product or a DIY?
@@GardeningInCanada no product in mind at this time, but I am trying to go all organic with mostly Tropicals in the desert of AZ. I am just curious about those because I was going down the rabbit hole one day.
I have a very hard time to get that to work. I gave up on the earth one sensor. Can you do a video?
So with temp, let's say I'm starting some tomatoes and I have a heat pad for germination. The info I've had is that I should turn off the pad after sprouting. I don't have a thermometer or anything, just stable inside temp of around 21, would you suggest just keeping the heat pad on all the way until planting out? If so what temp would you set it to? Love your vids.
My favourite video.
A little confused...
Thank you for this fantastic info. I am behind on my starts this year, seems like there still could be hope. I am in NY, USDA zone 5B. I do my starts indoors on heating mats and would love for the community to help me check my understanding.
Is it 30 degrees C during the day and 20 degrees C at night? Should I follow the same 12 hour and 12 hour approach for heat? How long do I keep the heat up for? Days? Weeks? If I elevate the plants above the heating mats once they germinate will that work for heating or should I switch to a heater?
Thanks
read some more comments, so the hotter temp is at night?
Quick question about light. Then why does Alaska have some of the biggest produce with their 24 hours flight in the summer?
Given the grow lights produce heat, you didn’t explain how you get higher temperatures at night. Are you using two different heaters on timers with different set points?
Sorry it’s the part where I show the ink biird. It’s a temp probe that controls the cool and the hot and turns on stuff accordingly
Great stuff thanks. I’m in Australia growing native plants a lot. They are adapted to low phosphorus soils. Apparently. Do you have fertiliser suggestions or comments?
Wow! I have really been winging it
Honestly the info here is just food for thought. Don’t get too hung up on anything in here. It all turns out the same.
Thanks! I have winging it results tho so this will help. 😂
