What is the most difficult for you to control? Temperature, Humidity, or Air Flow?
Definitely humidity!
Finding consistent sources for the soil I like 😤
You should be able to find soil in a place like Denver. There are people in third world countries who really struggle to find supplies etc. Have you tried reaching out to a local greenhouse distribution company or nursery? What soil do you prefer?
Humidity.... The place where I stay the humidity is usually more than 60%. I was thinking to put a layer of growing medium over the seeds and check how it works? I have already tried growing seeds densely and sparsely, both cases I got mold. Because I am growing microgreens at home currently I am not planning to buy a dehumidifier. What humidity level do you prefer in germination room?
I prefer my humidity around 50% but lately its been around 70% because of the humid spring season here and less air conditioning vs summer which helps to dry out the air.
Hi Donny,
my name is Jan im 25 y and a study from germany, since c. 19 in germany and the lockdown, i watch all of ur videos and this week my 1020 Trays arrived. my roommate (best friend since childhood ) is ready to start a business here in germany. pls keep going with this content.
Jan, thanks so much for commenting, I'm so excited for you and your best friend!!! I promise to keep making content for you, as long as you keep me posted with your progress 🌱💚💚
Hellow, where did you buy your 1020 Trays? I'm from europe too and I can't find one reliable
thank u
Hey @Jan, wie seid ihr vorangekommen mit eurem Business?
I bought mine from greenhouse international to save some money. They are too deep but I'm going to try them anyway. If it doesn't work out I'll use them for my outside gardens. They are the best made trays I've ever seen. Donny's trays are listed in the description.
Honestly, if my name were Donny Greens, I would've been selling weed.
And if I were selling weed… I certainly wouldn’t tell everyone on the internet about it lol 🤫
Greens isn't his real last name lol
Cool to watch your progress buddy. I have watched your business thrive over the years. 🙌
Much love!!! Thanks so much for following along with me 🙂🌱💚
Thank you, Donny, for sharing your knowledge.
great video Donny thanks as always!
Great video, Donny! Solid tips for the ideal grow space
Thanks so much!! Hope you are well, thanks for commenting 🌱💚💚💚
Great video Donny we like to think of the Airflow / Temperature / Humidity triangle as an equation, as in our experience the appropriate levels of each are directly dependent on one another!
We do however feel that if we had to pick the most important and the one we have struggled with the most over the years it would defiantly be AIRFLOW / Air Exchange!
A tip we think is often missed is that regardless of the amount of Air Flow in your grow, you will need sufficient Air Exchange, or you will just be moving stale air around, witch does very little good!
Speaking from experience :)
Love the triangle equation 💚 And you make a very good point with the air exchange. I see that being a difficult one to solve/implement. Lately i open both doors of my farm and crank the fans to clear out humidity. How have you improved air exchange?
Thank you Donny! Great content!
As for the likes, y’all can’t smash that like button and run up Donny’s videos! Come on y’all! Help the man out!
Hahah yooo my dude!! Thank you for that lmao. Thanks for watching, I hope it helped! Do you grow? 🌱🌱
Thank You Donny
Thanks Donny. This is great information. Temperature is my biggest problem. I've been growing outdoors where temp fluctuate between 40 celsius max and 20 celsius min. This is my biggest problem
Oof yeah thats tricky. I prefer to grow indoors and really control the climate
Thanks Donny!
No problem, my pleasure!!
Outstanding! Thank you
Thanks so much 🌱💚
Thank you for the useful imfo👍🏼
No problem Lisa, I'm glad it helped!
Youre a legend for this info dude. Seriously.
You're a freakin legend! Much love 🌱💚
Keep up the good work! 💪🏼
Thanks, you too!!! 🌱💚
your videos are so informative, thankyou for being you
Thanks so much Dev, I really appreciate this comment 🌱💚
Good content. Well done.
Thanks
How do you keep that temperature in winter where it gets below freezing? Great video.
Having issues with bringing in fresh air from outside where it gets to 0-5 degrees C. And then keeping the room warm. Do I need to bring in fresh air at night during winter?
Video very helpful now I know why my sunníes get mold because room temperature is 78-80 degrees that’s for the video
Boom! There you go Jose, I'm glad I could help you get to the "root" of your problem 🌱💚 Where is your microgreens farm located?
Always exciting to see a Donny Greens Upload! :P Will have to come back later for a full watch!
Yayy!! Haha i'm always excited to see the leprechaun picture posting a comment. Did you know I was born on St/. Patricks Day!? 😆
Great video
Thanks!!
For me. I think temp has been tbe biggest issue for me but as I increase temp and keep it stable I'm sure my next think will be humidity
Haha you will figure it out. Don't get discouraged, this is how you grow your knowledge!
Hey, I have a greenhouse 100'x40' and I bought 2 "quest 506" dehumidifiers to regulate the humidity. What's the best way to optimize the use of the humidifiers?
Am I supposed to close of all the vents when using the humidifiers (just like when you use an AC)? Or Am I supposed to let the vents opened?
Leaving the vents opened brings air from the outside and help with air flow and reduce the temperature. However, if I let the vents opened (at night or when it rains) I feel like there would be more humidity coming inside the greenhouse.
I cannot find any good info on how to maximize the use of a dehumifier in a greenhouse.
What fert do you use on those eyebrows they are cranking :) I enjoy the vids and have learnt a lot from being a complete noob. Thanks dude
Lmaooo thanks a lot, glad my content is useful! No fert for the brows, just some consistent tidying LOL
Is the temperature and humidity ithe same with hydroponic micro greens
hi donny how many hours do you illuminate your lighting system for micro greens
Hi Donny I LOVE your videos, I am a complete novice when it comes to growing microgreens. Here's my situation, I live in Las Vegas, NV this entire week we've had outdoor temps at 117 Degrees daytime and low 100's at night. Regardless of what temp I put the AC on it cannot keep up. I have indoor temp of 80 degrees. I was considering putting insulation on walls and then creating a plastic room inside my grow room. I also need to figure out my humidity since it is extremely dry. I have metal racks, The reccomended trays, Tru Leaf seeds, The ideal soil mixture ( i hope) fans and sunblaster lighting. ANY suggestion you may have to get the room temp correct would be greatly appreciated.
insulation could help for sure. So could a bigger/better AC unit or multiple.... Gotta get that climate dialed in!
What humidity percentage do you keep your germination room at? Thank you
@Donny Greens - Seems like a silly question but ill ask anyway. How do you maintain a temp of 73 degrees .. just with a thermostat? Also, what temperature do you keep your germination room at?
Hi Donny, I grow in the mountains of Costa Rica with high humidity, using a dehumidifier brings up the temperature. I probably have to buy an AC. Is there any way around it?
Thank you for the most useful information .How old are your broccoli microgreens in the background ?. Do you wait for a true leaf to emerge before harvesting?
I don't really wait for a super visible true leaf on the broccoli. I harvest them when they are 10 days old. Thanks for your comment! 🌱💚
Hi Donny! I'm currently growing in my basement and have made back more $ in 2 months than it cost me to set up! A slight problem I'm seeing is that some of my trays seem to sag a little in the middle, due to the raised edges of my shelves around the top. I'm using the wire racks that are similar to yours but in chrome. Do you use some kind of plastic barrier in that space inside the perimeter of each shelf to compensate, or have you not noticed a difference? I'm thinking it's why some of my trays have smaller and weaker plants on the front and back while the rest of the tray flourishes. Thanks for any tips!!
Hey Stephen! I am a traveling private chef, but considering a switch in professions. I love the health benefits of microgreens and know there’s a demand back home, especially for chefs (just for garnishes). I would like the set up a microgreen farm in my basement (like you mentioned in your comment), and I was just wondering what hoops (if any) you had to jump through with authoritative entities like the health department while growing in your own home. Is it one of those situations where “it’s easier to ask for forgiveness thank permission?” This question/concern is probably the only thing holding me back, aside from quitting my job.
Any info or encouragement is appreciated! Thanks!!
Hi Donny,
I have been growing microgreens for a month. I can't figure out if humidity will affect the yield/growth of my plants. My room is very humid (around 70%) but I haven't had any major mold problems. Should I buy a dehumidifyer to have better yields?
Thank you so much for your videos and support group, God bless you!
Much love Miguel 🌱💚 You normally won't rn into problems - it sounds like the other factors in your grow room are good. If something else slips or you overwater a bit, having a dehumidifier will help to keep yor overall grow more resilient.
Hi is there reason you have separate rooms when you germinate now ,to when you first started out? TIA
Thanks for the good advice ! Do you know what cause black spot on leaves right after germination ?
No problem! I often find that happening when there is excess moisture
@@DonnyGreens good to know, thank you !
Thanks nobody talks about this
Temperature. My basement is constant 66 degrees to 68 so my first attempt at germination is seeming to fail. Finally got all set up and bam, not fun. Humidity and air flow is fine.
get a tiny little space heater. you are basically on temp
Great video. We are researching growing microgreens (as a hobby, first) - but my biggest concern at this point is the growing environment. The only space we have available is our basement, which stays consistently at 62 degrees. Are there grow lights that also generate heat, possibly pairing these with a reflective/insulated draped over grow racks, but with ventilation slots for airflow? We want to get something small going, but we have to use what we have available at this time.
Thanks for your comment! I think growing as a hobby first is a good idea because it’ll give some insight as to whether you will like doing it as a business/career. Fluorescent lights like the ones I use will help drive the heat up a bit in your grow room. I wouldn’t drape anything over the racks. How big is the space you're working with?
I’ve been trying to get my micro greens business up and running. My grow room is in my basement as well. I have two dehumidifiers and a large floor fan. The humidity stays right at 50% and the temperature stays around 70. I have to say that I worry that the greens smell musty. I don’t smell a musty basement but I worry that when the customer gets their greens home they may smell musty. I’m really rethinking putting it in another part of the house
Lavendergal - We haven’t had an issue with a musty smelling microgreens so far. Our issue so far is getting even heating. We are using 10x20 heat mats (with thermostatic control and a temp probe inserted into our soil), but the heat mats do not produce even, edge-to-edge heating. The edges of our trays do not grow as evenly as the center 90%. I feel like the only way to achieve this (since our basement is so cool) is by creating a microclimate for our grow racks to create an evenly heated, steady environment. Not sure how to achieve this yet. Once we have a dedicated space in our future home, it won’t be an issue. But for now... thinking about creating a “wrap” to insulate our racks from the rest of the basement, to contain the heat. Since we have small fans on each rack, we’d still have circulating air, but I worry a closed environment would get too humid and too warm, and be difficult to regulate.
Thanks for another informative video Donny! My airflow is a challenge> I have an infinity computer fan on each shelf, I also have three small honeywell fans in the room, one on the top of the rack blowing the warmer air away from the rack and two about 8 feet away one at 30" above the floor and one at 55" pointed half on the rack and half in front of the rack. Im trying to create a circular type of airflow. Should I avoid blowing directly on the rack?
Interesting, that does seem like plenty of airflow. Why do you say it is a challenge? Send some pictures in the facebook group and tag me so I can see your space.
Donny Greens I will do that! I have changed too many things at one time...
@@DonnyGreens you can see my set up here... ua-cam.com/video/uuiTr8u6_yg/v-deo.html
You have a very small space and only one rack. You don't need to go so overboard with the air flow. The fans on the rack are probably fine. You don't want air blowing directly on the racks and drying out your greens. Not sure what you are having a challenge with?
Donny Greens that makes sense, I was dealing with some areas on the rack drying out. Thank for taking the time to help.
Hi Donny thank you for posting your video, where do you buy your dehumidifier? It seems like the room where I grow my greens is always 75% humidity. Is that bad?
It's not necessarily bad if your crops are high quality. I bought my dehumidifier from a local hydroponic store that was able to sell me a Quest Dehumidifier. Does this help?
Donny Greens thanks you’re the best!!!👍
Mould can't form at 70% humidity or lower :)
One more question. I very rarely get mold on a tray but when I do I throw the whole tray out. Do I really need to do that? Or can I salvage some of it.
I answer these questions in my other videos. Have you seen them? I highly recommend subscribing to my channel and watching all my videos. They will help you. ua-cam.com/video/Q0PgsHAYLMQ/v-deo.html
Is that 70° in the winter time? Or all year long. My AC air is on 78° right now and I'm cool. But in winter my heat would be on 70°
Hi! Thanks for videos. I'm starting a microgreens business and have some doubts and questions. So you actually have a separate germination room? Did it ever happen to you that your plants get mold in the germination phase when trays are stocked one on top of another?
Every once in a while ill see mold on maybe some sunflowers but i don't really have mold issues, no. I have a separate germination room in my current farm but the germination was in the same room in my previous farm.
@@DonnyGreens thank you very much ❤️
Do any microgreens need a humidity Lid on top of them?
How would I start this process at home ?
Just seen a video from someone else's channel and finally found this one
glad you found the best microgreens channel ;) welcome
If we start off smal in oit house how are we supposes to germinate and then grow in seperate areas ?? Please help!
You can surely germinate and grow in the same area
These T5 fixtures are somewhat pricey VS like a Barrina LED. Is there any reason you are not using LEDs? If the LED fixtures has similar spectrum, wattage, Putting down same PAR(intensity) and the correct color to match flourescents can you use LED. Maybe you started before the LED craze.
Can you suggest online courses to learn the techniques
There is a course linked in my video descriptions and is the course I started with. It covers the basics. UA-cam is a great free resource. And we also just started an MBA (Microgreens Business Accelerator) program which is more for people with an already-established business. I hope to create my own course in the future but all I have so far are these videos and a small instagram feed haha. I'll keep making more content which will help you
Hi Donny,
I have tried growing peas microgreens but I see the seeds to melt, rot, smell and mold....could you show how do you grow pea microgreens?
Ill have to make a video on that. Are you using seeds that are rated/meant for microgreens ?
Is there are recommendation of how big a dehumidifier is needed for a certain size room? Do you keep a generator?
I don't have a generator but that is a a great idea to improve resilience! Dehumidifiers typically have ratings that will inform you of those types of details. I use a big dehumidifier by Quest that is made for commercial agricultural operations
@@DonnyGreens Thanks the the info!
could you link the fans that you got?
I gottem from home depot
Donny, do u have an "out fan"/vent in your microgreens room? I just moved to a new space and i dont have an opening for an out fan, i do have an ac unit though. Is it enough in your opinion?
Its probably enough. I've never had an exhaust fan/vent in any of my farms
What do you do if the humidity is too low.? The humidity fluctuates from around 25 - 30 percent. Is this okay? Everytime I put my broccoli microgreens in the light after the blackout dome they begin to fall over. I think this is because it is too dry. I initially thought it was because it was too cold. I increased the temperature from 70 degrees to 76 degrees.
Chad i think i answered this in a FB group for you but I would skip the blackout dome. You need to water them right when they go under lights. They're falling over because they are dehydrated. Your temp is fine. Humidity is a little low which is causing them to dry out a little fast. As you add more trays to your grow, it will increase the humidity, or you can use a humidifier in the meantime.
how many hours a day should i keep my microgreens under light
Hey Danny great content. You said you keep your germination room at 70%. Did you mean 70 degrees? Would an screened porch (where nature controls the temperature) be sufficient for germination?
Hey DG new subscriber here. Is outside air important for the C02 consumption of microgreens? Most a/c units are recycling air already in the room/home/building. So I imagine C02 isn't coming inside most people's grow areas unless they open a window or something.
That air exchange typically happens naturally. Its nothing you typically have to worry about with the microgreens
Should they be on a light schedule like 8 hours darkness or something similar?
Yea exactly. I run mine 16 hrs on i believe
Can I ask how you started in parent's basement, re humidity and temp control?
Dehumidifiers get the job done!
I have closed balcony, and it’s cold , I was wondering if I should leave them there , inside my apartment is warm
haha get those things inside!! 70F is the roundabout temp you want them at
If the humidity is 20-30%, should I use humidifier to increase is to 45-50%?
If its drying out your crops too fast, sure. Or you can grow more in your space which will also increase the humidity naturally.
I live in Phx and growing out of my house. If I keep my house at 73 degree it will cost me an arm and leg. I am considering using a swamp cooler in a single room to keep it cooler but still may not be able to get it to 73 degrees. Any tips?
Oof, I feel your pain. That's actually a dope spot to be growing. My sister is moving out there in a month and I have been toying with the idea in my head of making a satellite farm out there. I hear there aren't really basements out there right? I'd think that a basement would be kept cooler because of the natural insulation via the earth. I would keep the small space where you grow air conditioned. It will cost money, yes, but it's worth it. Hopefully the room is well insulated. Use an efficient AC unit. Other than that, climate control is just part of the business and geographical location definitely does effect this, hence 120 degree Arizona days. Lucky for you, Pheonix is in the top 10 healthiest cities in the US so the demand will lead to sales which will allow you to pay your electricity bill! I know this isn't the greatest answer but I hope it helped at least a little bit :)
I live in PHX too and I agree, I added two small humidifiers to reach the 50%. This summer our AC blew out with the months of over 110 F so I bought an AC that is mobile. I bought a new AC unit for the house, but at 73 F as you said I will go broke. Is there any way we can connect for a chat?
Is there any alternate to Air conditioner?
You need to be able to control your climate and temperature is one of them. Air conditioner is what you use if your temp goes too high
Hi Donny, My growing space is 6,500 sq. ft. How big should my germination space be?
Wow! That is a huge space! I think your germination space should be about 1/5 of the grow room, but that’s a rough estimate and everyone’s situation is unique. I still think in general this is a good rule of thumb, does this make sense?
Hi Sir, Can we control the temperature and humidity by installing AC
Please also tell me which one is more convenient for Microgreens AC or Dehumidifier
Do you keep a fan on you germinating plants?
No, do not point wind directly at your plants. Airflow in the room is good. Just keep the air moving
How do you find out how much to sale them for.
Make sure you are making the margins you want to be making. You can also check what they are selling for in your local area to get an idea and also dont be afraid to snoop on other microgreens growers' websites!
Is there a difference in growth with air-conditioned 73° vr a heater 73° in winter months?
Humidity might have to be adjusted differently
Should be pretty similar
My temp is Malaysia is averaging
79°C °F
Precipitation: 31%
Humidity: 90%
Is this gonna cost more for needing AC year long?
Ummm... yes. Your room is way too hot and way too humid
CO2 levels?
Hi. do you do day/night temp cycling, i.e, cooler night temp? or uniform temp all thru the day? thanks.
Uniform, i try to keep it around 72 F
I am in India- I feel like I could not have chosen the worst time to start my business. The storms are increasing the humidity and the Monsoons are around the corner. I am controlling the temperature with an AC - but the Humidity is devastating.
also the racks just arrived and for no apparent reason the growth is very uneven in the trays- any ideas why that might be?
Tricky stuff but this adversity will make you a stronger entrepreneur 🔑 Uneven growth could be due to poor germination or overwatering.
I am suffering poor gemination of sunflower seeds...can the seeds be a reason for slow and uneven germination
This may be a random question but I’m wondering if you have found any recovery remedy I’ll call it- for when the greens lay down. When I got home from the farmers market today my sunflower seeds and another micro green head kind of laid down in the tray . It had been About 16 hours since I watered them last and I’m afraid that’s what happened... maybe they were thirsty.
Yes, im sure they were thirsty. Watch this video: ua-cam.com/video/PtfOnYs0GY4/v-deo.html
Are water important to microgreen growing?
Very dissappoint now
air flow
Thanks for your feedback Steven!
