For what it’s worth, between 1985 and 1990, using NFT (nutrient film technology) testing cultivars of Cos lettuce, Bib lettuce and spinach, I found the optimum vegetative root temperature to be 84°F.
Cultivars were germinated on Rockwall blankets using tap water with high calcium content , pH around 6 ( from memory) and zero chlorine, then transferred to individual growth stations in an NFT system. Once individual plants were transferred into the growing system, the nutrient solution was held at an EC of 1.2.
The objective of the experiment was to determine which, if any, root temperature gave the most vegetative growth. I don’t remember doing any taste testing. I merely measured the height and robustness of the plants. It was not a double blind study, I only tested for the purpose of determining optimum root temperature.
I can't wait to chat with you soon! You seem to have a wealth of knowledge! We are about to move and then I'm hoping to find some time to drop by if that's good with you.
Thank you so much for sharing, we will give that temperature a try and see how it goes!
And another GREAT video! Thanks for running all of these helpful tests and recording them for the masses. Yall are the best!
🥳 Thank you for your amazing feedback, made us both smile.
Thank you for another great video. I just ordered items from your amazon store to start my first microgreen grow!
Thank you Daniel for supporting us through our Amazon Store!! That will help us do more experiments!! Your awesome and hope your first grow goes amazingly!
Interesting. I look forward to the experiment with the stacked trays. Thank you.
Thank you for watching!
FANTASTIC VIDEO
😊Dan McCollister Have you signed up for our Master Class yet? Please get ready to take advantage of all the information we've assembled for you!!!
Great video.🎉
GREAT VIDEO!! Man what a difference between with/ without heat mat. Just bought it myself using your guys link along with the temp control. Thanks!! Grow on!
Thank you so much for the support Dennis!! We are so excited to hear how it works for you! I'm looking forward to seeing how it does this summer as the temperature rises... Wondering if I can use it even on hot days to further help germination. We shall see! Thank you again for your continued support!
Great video, interesting comparison indeed. Thank you for the info!
The Farm Dream ?
@@amandaslamm5703 Sorry I see that I misunderstood the ending! *edited*
Thank you so much for your support and feedback! 🥳
Thanks guys, it’s because of you I decided to go with the same brand and I set up a number of rack systems. So far I have notice a number of benefits, germination is quicker and more even and I seem to be getting healthier crops. Thanks
🥳 That's so awesome to hear Jason!! Congrats on your new setup, glad its working out so well. Thank you for watching and supporting us.
Another great experiment! Will be interested to see the stacked trays.
Thank you so much for the continue support Ben! We are starting that trial tomorrow, so we should find out in 7 days!
Great video 👍👍
Thank you! 🥳
Being able to turn a shelf around in 7 days is a big advantage if you sell at a weekly market
Very true! 🥳
That was very interesting!
Keep me posted please😊
Thank you for watching! 🥳
Very good comparison. So, a slight edge for the heated trays, maybe gain a day. Only a small advantage if heated.
Thanks for sharing you knowledge. Very well done videos.
Thank you for your feedback 🥳🥳 Glad you enjoyed this video.
Really enjoyed the video very informative! Noticed some new lights on the right hand side are y'all gonna review those as well?
Yay thank you! Yes, we just started filming the experiments we're doing with them today!
Bring on the heat....YAY
🥳🥳🥳
Awesome experiment. Good stuff. 1 day gained. Heavier yield. I'm buying a bunch of heat mats
Thank you for the support! I'm excited to see how it performs with stacked trays!
Thank you liked + subbed
In a commercial grow an extra day advantage would be financially better with a full rack of sunflower over a whole year. One interesting experiment would to use the heat mat just for germination only then end it on shelf without heat to see if you would get a higher yield or not. Also it would be interesting to see if germination percent is better with heat mat or not. Great video that raises even more fun experiements.
Exactly! It really does raise more questions, especially because I've only experimented with 78F... I can set it up to 108F, so I kind of want to play in 5-10F incremental increases to see when it doesn't help anymore. I will start an experiment and try your suggestion! Thanks for sharing and your support!
Great video!! When are y’all going to do a live AMA session??
Thank you! Great question, we've discussed doing a AMA session. Currently we have a lot on our plate since will be moving very soon, but once we get everything re-settled I'm sure we will start to plan out a good time!
Cold frame experiments would be fun for you. Your experiment is same theory as raised beds or planting next to cement as it turns into a heat sink.
We will be doing some outdoor experiments soon! We just secured our next house so we are really excited to get some raised beds and have a combo of indoor/outdoor experiments!
How about doing a trial with four trays, one with heat through the entire growth, one with heat germination only, one with no heat but same amount of time, and one no heat that gets and extra day to see if it catches up?
Great suggestion Patrick! Will write this one down on our to-do list 🥳 Thank you
I agree. Would like to minimize the time the heat mat is plugged in if it is only useful for germination.
@@OnTheGrow id love to see this too.
Thank you for the experiment. Where did you guys purchase those red led lights?
Thank you for watching!

На самом деле, интересное видео. Спасибо.
Развитие Микрогринов в России набирает обороты, и тем интереснее наблюдать, как вы это делаете.
Чтобы в дальнейшем перенимать свой опыт, применяйте его.
Большое спасибо за поддержку! Мы рады слышать, что они набирают популярность! Они такие удивительные культуры для выращивания, и я вижу, что их популярность будет расти в течение следующих нескольких лет. Еще раз спасибо за поддержку!
Great vid thanks again. I wonder how much weight the non-heatmat trays would have put on if they were left for a day longer than the heatmat trays. In any event it seems worth it to use a heatmat considering the day saved on shelf space which is important for turning product around quickly plus a day saved on lighting.
Thank you for the support! I really think that the tray without heat could've gained the 150g difference with another 24 hours. A day quicker turnaround, over the course of a season is a pretty massive gain.
Nice experiment you two! For consideration, what may happen if a no direct heat tray is put on a bottom rack, a no direct heat tray is set on the rack above to receive the passive light heat from the no heat unit below, and a direct heat applied under a tray on top shelf. 3 shelves, 3 variations, is the middle shelve the cost effective beneficiary of the passive heat? -Bob...
I like this Bob... I think I may start a test for this tomorrow... Thank you for the suggestion and the continued support!
Hey, I have been watching through your videos making sure this experiment has not been used already. This will be a light experiment, could you do a test on white, yellow, and red and blue light for plants? Thank You
We have not yet done that test. I will get that put onto our list of videos to make! Thank you for the suggestion, I think that will make a great test!
Can’t wait! Your Welcome.
I assume you are still rinsing the seeds - just to clean them before starting the germination process - like you recommend doing in your earlier growing guide?
If you had two seperate rooms for germinating and growing, I think you could even lower the ambient temperature for germinating like 1-5C°(?), have the same grow results and save on electricity (I would say, the heat mat doesn't use as much electricity to heat than to heat the air ... )
Great video overall, thank you :) maybe you could "cut" some corners in the video and save like 3-4 minutes :)
I think that could be possible! It would be interesting to see what the difference in cost would be... Absolutely! We are trying to find the right balance between sharing test information and time... Thank you for your support!
Environment temperature would be interesting.
Hello CeleCraft ! Our space stays between 75-80F degrees in the Summer (Best Germination Temps) and between 67-73F in Winter and our humidity around 50% or under. We also have one large fan that circulates the majority of the air and small computer fans on each shelf of each rack. All fans are running for 24 hours of the day. We do not pump carbon-dioxide in the space and the space only exchanges air when we open the door a few times throughout the day. 😊 Because we grow in a trailer, we already know that all environmental factors are huge..temperature swings and humidity are a few!
I would guess that the heat mat would be even more beneficial to those of us who grow in cooler ambient temperatures
😀You are so correct to get the temps up during the colder months...the mats help!!! 💚Thank you so much for the feedback j majick! We appreciate your support!
What if you use a slate tray instead of a heat-mat? Slate should hold and retain the heat from the lights and you don't have to put any extra energy (electricity cost) in there.
so the question then arises: may it be better to heat up the whole room by a bit - money efficiency-wise - if it takes down the "time to harvest" by 15% (possibly for other greens too)
Great question! Will have to dive more into that one day, but the main problem we see is potentially humidity. But if you have a dehumidifier it should work.
700 grams damn! What kind of nutrients did you guys used? Also would be nice if you share the temperature and humidity for each day. Keep up the good work 🙏🏽
I'll link it to you haha That's a great suggestion! 🥳 Thank you for watching.

Hello all does anyone know of an alternative to the ocean solution feed? I'm in the uk and the don't deliver here or there is none in stock? Alfalfa seems to be the closest but cant find it in liquid form. thanks for any guidance .x
Does suggest to keep costs down while still getting the germination improvement that one might use heat-pad for only first 2-3 days and then treat them the same.
This would cut heat cost in half while seemingly not making growth suffer.
I would say yes to this! I think the main benefit happened in its first few days of germination and we didn't see any other crazy growth after that point.
Hi CJ, can you confirm if you have used H2O2 during the initial germination phase. Cheers.
We only use it if we have to spot treat for mold, or on sunflower husks because they breakdown and start molding.
How much does it cost to run a heat mat I wonder?
So perfect.. so perfect..How?? Its 30° C normal here... 😅 I am facing mold issues lot. I m unable to figure it out.
That's how it is here in Texas in the summer. We average about that 30-32C range. Have you tried adding airflow? Also drop your humidity if you can... stay below 50% if possible. We keep our humidity around 35-50%. You can also send us Instagram messages with pictures of your setup and we can help you troubleshoot it!
@@OnTheGrow actually right now I can't afford indoor set up... So I have outdoor setup in shade house. I am impatient with growing so usually in excitement I wet too much and than because of heat nd high temp... My media (coco coir) get a mould issues. So my friend suggested me to add some construction sand in my media. Would u suggest me to do that?
THE D sand is a great option! Anything you can do to get some aeration/drainage in the soil. Perlite would be great or anything you can get your hands on that farmers use to get better aeration and drainage into the soil.
I'm about to purchase these mats. Do you know if they daisy-chain with each other and does each one need a controller individually? I can't seem to find this information anywhere.
Hello peter, I'm sorry but we can't find that information either :/
So - newb here. We have a cool basement (61-62 degrees, on average), could you use these heat mats full time to create a warmer microclimate for the entire germination and growth process?
I believe that you could! I would make sure that you use a thermostat for the heat mat though.... otherwise you’ll be cranking out 110F heat the entire time and they will grow worse with heat over 90F
How much water solution did apply in bottom watering?
When we mix in the nutrient OceanSolution, we use it at the ratio of 1/2oz per gallon. We've had pretty solid results that way... When we bottom water the crops, we generally start with 3/4cup of water twice a day in early growth and 2 cups, twice a day for late growth.
Do you think taking them off the heating pad after the 2nd or 3rd day would hinder the growth or keep them a day ahead still🤔
From our tests, they stay at 1 day ahead and it hasn’t hindered the growth. It just gives them a head start out of the seed shells and then they grow normally
Were you ever worried about the extra moisture causing problems from the heat?
Thank you for watching terry lassiter!!! 😄 Glad you enjoyed it! No...everything tested out fine...hope it helped you!!!
is all microgreen need weight?or only sunflower?
Not all Microgreens need weight but a lot of them benefit from it. We have a bunch of How To Grow videos that can show you which ones do and don't need weight.
What is the pH of your water?
Unbalanced we sit at about 8.0 and we PH Balance to the 5.5 - 6.0 range.
Hello.Tell me,please, how to fight mold?
h2o2
Thank you 👍
Exactly! Some Hydrogen-Peroxide will usually do the trick. Airflow is really important also, so make sure you are moving the air around if possible. Even small fans make a big difference. Make sure you aren't adding too much water also...
I only know that because of these guys :)
Why do you use purple lights
We use them for experiments. But different light spectrum's (colors) have various effects on plants. There's ton of research on this subject via Google! 🥳 We're testing it out on Microgreens to see if it changes anything in the overall growth, appearance or flavor.
Good afternoon, if you can, please include the translation of English info Russian or Armenian, please
Hello! We've been discussing how to do this recently :) Hopefully soon will have some our videos with this option.
Thank you very much for your response 🍀🍀👍👌
Maybe stagger the start times by 1 day so you can harvest at the same time with similar growth and then compare taste and weight?
that just makes the same test harder to administer.
We could give that a try! We've postponed the heatmat trials because it is getting too hot in our growspace, so we don't have the cold temperatures like we did a few weeks ago to test.
