✅ In today’s video we put three different types of lights to the test, T5 HO Fluorescent's - vs - 18watt LED's - vs - 300watt LED's to see which one comes out on top for growing Microgreens. All the details about the lights are in the video - such as LUX, light distance, cost to run the lights and so much more…. The results are worth the watch! 🤯
This video is one of many of our experiments Microgreen lighting experiments and if you would like to see more on what the effects lights have on Microgreens --- be sure to check out our KZfaq Playlist on lighting, and if you would like to see the complied data from all our lighting tests leading up to 2021 it's available in the "lighting" section of our book "Becoming a Microgreen Master".

Interesting that 4.13 times more light ONLY produced about 16% more end product.. reasonable to speculate the limitation is the surface area of the leaves to absorb the light. Theoretically, a 28 watt LED of equal lumen output could yield the same as the other harvests at half the T5's power consumption. Realistically, I don't think it would as it would most likely use less bulbs decreasing the uniformity of light distribution.

Amazing experiment, thank you. I am as a city farmer (indoor) for more than 10years made my personal conclusions from this video: 1. Total Wattage does make difference 2. Shelf 2 and Shelf 3 - how to get near similar produce & product top look from cheap shelf 2 same as shelf 3 -> place 4 LED lights 30W-35W each on shelf 2 -> you should get these extra 60-70grams. Also if 2 lights will be 6500К and 2 lights will be 6500К+2700К you will get that vibrant look of mg's. And all that will be for the 1/3 cost of Shelf 3 😁😂Did you get to that and experiments in these 3 years ? Interesting to know what you finally came to in years. Healthy harvests)

Just wanted to point out that because the top 2 were sitting on top of warm lamps; this may be the reason that they dry out more. This might also account for the lower harvest weight.

@OnTheGrow 4 жыл бұрын

Great observation! Yes, they both had the heat rising from the lights below, but we actually found that a little heat helps with the growth... It could potentially dry it out more though, so you are correct. We will find a way to experiment better with it!

@hammerfallen12345 8 ай бұрын

Or maybe shadows in dense vegetation made those variations. Better to make a growth with not that dense vegetation... That would be a better comparison with those different lux. What I have read about lettuce for example it's better to have more space between plants... It will get bigger yield.

@lecutter9382 2 жыл бұрын

Another cost issue that needs to be addressed is the longevity of those different lighting systems - the lights AND the ballasts. I think in most people's experience the old adage about 'you get what you pay for' is generally true. What are the manufacturer claims for the life of those lights? I'd love to see you update this - now 2 years on since you first posted this - on how they're all still doing. And don't forget that increase in product from the bottom light is cumulative over it's lifetime, which is a further cost reduction overall. Beyond that, most people also don't have dedicated growing sheds and have to grow them in their homes. Cold light isn't only irritating but the blue spectrum is bad for eyes - pets and people. The warm light of that third rack is much more beneficial and easier on the eyes for everyone who has to see it. So, yeah, I'd say it's worth the extra dosh.

Great content! So - and correct me if I’m missing something - on a 48” long shelf, using the 42 watt LED grow-cycle cost of $0.55 - the energy cost/tray would average just under $0.14 per 358 g of greens... Not bad, bud! Even using the expensive lighting, split between 4 trays you’d be at $0.3125 per tray per grow. Sweet!

Thanks for a great, informative video! A key advantage of higher light output is the ability to support thick canopies. That manifested as greater yield in your bottom sprouts. High light output becomes especially important for grow tents with mature plants such as tomatoes, whose leaf canopies are at least a foot thick or more. However, for microgreens, super thick canopies may be less important given that growth time is so short. In particular, the intensity of COB lights would require greater shelf heights to avoid burning the sprouts and would thetefore actually decrease yield per square foot. Your video has inspired me to retire my blurple sprouting leds and I will now invest in the full spectrum panels that you used for your bottom shelf. Thank you!

Huge fan of your guy's work and rigor in collecting the data for these different variables! It's been very fun and helpful watching you guys grow (both channel and product). I was wondering if you guys tried playing around with different wavelength lights for your grows? Have you tried using "grow spectrum" lights that blast the blue-red spectrum? Haven't seen any of these lights in your videos, so is there a specific reason you guys decided against them? Thanks for the content, keep up the great work!! By far favorite microgreens channel on YT.

Thank you so much for the support Timothy! It means a lot to us! We are about to begin playing with more spectrums like what you are discussing. We have some blurple lights we are going to test first with some more powerful daylight LED's. We don't love looking at the multi-spectrum lights because they are so hard on the eyes... We have used them in the past, but you have to wear glasses to observe the crops. We did love our blue spectrum lights, they gave us amazing results... but for some reason the vendor stopped selling them :( Stay tuned for some more lights tests soon! Thank you so much for the kind words, we really do appreciate your support.

Really good to see! I'm surprised by the results, I thought the 18w LEDs would be less productive than the others, but only just. It would be good to see how the distance from the light to the crop would affect yield, also reflectors and side covers to minimize light spill. Top job, subbed!

Excellent test, thank you. I have the 18 watt lights in white and pink. I'm going to try 2 white and a pink pet shelf to see what happens. Keep it up man, I'm over in Azle north of Fort Worth and have 2 racks to try this out. First for the family to see how we like them, and then maybe hit a few farmers markets for fun on the weekends. I'm an aircraft engineer full time, so can't make a run at it like you guys, but I think it would be fun for the whole family to give it a go. If it works out, I have a 1200 sq foot insulated shop that I could convert if I wanted to. Solar panels coming, along with lithium ion batteries, so Browning this stuff of grid would be awesome, and doablea long as I stick with these leds. Use to grow corals when I was your age with 1200 watts of metal halide , and 440 watts of VHOs...... Want to talk about an electric bill!!!!!! Keep doing what your doing with the testing, I love it. I am also interested in doing mushrooms, if you ever decide to get into that.

Thank you so much for the support!! I can't even imagine that electricity bill! Microgreens are so dang tasty and really addictive once you start growing them...

We are also interested in mushrooms and we should be attempting some in a few months. I hope they are easy enough to work with and we would love to make videos on it too! Thank you again for your support, it really does mean a lot to us.

so wait - how much is radish per gram? -- you had a higher yield from the more expensive and brighter lights - how long would it take to recoup the higher expense? even if it took 6 months you would have years of higher crop yields --- you would make more money and have a better looking product. makes no sense not to use the more expensive lights. so - how long would it take if you always get better yields to pay off the added expense? it's all money in the bank after that (unless the lights wear out too soon). also, the middle tray was probably drying out faster because of the hotter, higher wattage light being beneath it. next time put the high powered lights on the top shelf.

Great research! Have you ever reviewed the extensive research done by Dr. John Ott, during the 1980's? One of the many things he learned was that the color of the light affected the growth of plants (and animals) AS WELL AS the electro magnetic field produced by the cathode and anode ends of his lights. His work was mostly before the l.e.d. era. He created a research foundation to promote and collate his discoveries.

If you took the extra 2 ounces from the sprouts on the bottom shelf, and sold it for six dollars a container at the farmers market, that would be an extra $120 for 20 racks, providing that you got the same extra yield every time. That would pay you back for the more expensive lights in seven weeks, then after that you would have an additional $120 in profit per rack, or approx $12k per year for the two racks I can visible see on screen.

Hello,nice work and keep going,on growing lights you need to look after PPFD(avg at certain heights) for plants and efficacy for your wallet( PPE as μmol/J);also between the three of your testing lights only the bottom one is a real growing one,but imo is overkill for microgreens - you can grow plants into flowering stage successfully with that,tho it has a nice feature being the lenses wich improve the light coverage (and maybe the PPFD);sadly a good spectrophotometter is starting at 2000$;P.S. radish is not a demanding crop,you could try a slow/hard growing crop to test for a more acurate result.Cya!

Excellent. Thank you for this. I've just found you but I'm quickly going through your library of videos, can't get enough. Would be interesting to see this compared to summer and winter daylight (location and weather is of course a factor in that too). Not practical inside of your trailer perhaps, but just as a comparison. I'm in the process of building a year-round greenhouse on wheels. Plan is to grow with daylight, still very interested in this though, for the science of it. One might theorise that lighting could affect nutritional content of the veggies too. All the best from Sweden.

Had first back surgery 15 years ago and out of boredom grew weed with fluorescents t12 bulbs. Don't even really smoke weed but learned cloning, seeding, moisture, and many other things effect grow rate. Even the height from bottom shelve to top will effect by temp. My lights I always tried to keep as close as possible without burning leaves. Be really careful on mediums , dirt tracked in, or visitors bringing any unwanted aphids, mold, or other contaminants. Could cost you big. An oscillating fan always helped to make plant stems stronger. And I the light spectrum that has huge effect. Plants and plant ages loved different hues from red to blue spectrum. My plants were in attic and loved 100 plus summer heat.

quick question. Is it one harvest per tray? Or do the plants come back and you can get another harvest before composting the grow medium?

@OnTheGrow 4 жыл бұрын

Great question! Most varieties will not grow back again, but some will like Pea microgreens. I'm actually working on a video for this right now...but it will still be a bit till its out on KZfaq. But what I can tell you is it's really not worth it. I noticed that on the first harvest I got an amazing harvest, then on the 2nd harvest it was more than half the weight of the first harvest I got haha. Really disappointing. So I found that it's more worth it to just replant.

I recently discovered you guys and the content is awesome. I've got a small indoor nft lettuce system going and starting wheatgrass/microgreens now. My question is I believe the test may be more fair to the led tubes if you use 6 per rack to get the power draw per shelf even between types. There only $5ea in the 10pack which would be $30 per shelf for lighting with yield closer to the best one. This could be very cost effective and profitable if it makes gains over only running 3 per shelf.

Your welcome, it’s nice how much faster we can learn and improve through shared experiments. After watching your videos I’m running a test on those same lights on leafy greens grown to adult size in nft. NOTE I suggest using foil or something reflective on the shelf directly above these lights. In my initial check with a cheap light meter I got 3x more output with a reflecting top. The lights have a wasteful reflector for plant use

Nicely done. You mentioned that the bottom led is full spectrum, however it looks heavily in the 2700k-3000k range much like a high pressure sodium (HPS) bulb. When I think of full spectrum I think of a Quantum board with a mix of 3000k-5000k diodes with infrared and far-red in the mix (which almost produces a normal day light looking light) with little to no yellowish tones. Either way brother nicely done. If I wasn't so poor I would send you a real QB with a real full spectrum!

@OnTheGrow 4 жыл бұрын

Agreed on the temperature being around the 2700-3000k. I just took what was stated in the description on the LED and used that to describe it. My other full spectrum lights are like you describe with little to no yellow. We will be playing with a lot more lights soon!

You guys always produce great content. Have you compared these rigs taking the longevity in consideration? How long will the T5's, the LED tubes and the high tier LED panels last and how much will they cost, say over the span of a year?

@OnTheGrow 4 жыл бұрын

Great question and thank you for the support! The LED's are supposed to last over 50,000 hours... We have used ours now for about half a year at a rate of 17 hours a day. So far we've used 3,102 hours of their life (supposedly). To get it to a year, we would be at the 6,204 hour mark. At that rate, the cheap LED's should last about 8 years. The T5 HO Fluorescents are rated for only 10,000 hours total... We've used ours for a year at the same frequency as the LED's which means we have less than a year left on the Fluorescents before they go bad. So we would have to replace all of our Fluorescents next year at their premium price if we wanted to keep using them. Glad you asked, this would've been a great point to talk about in the video. Thank you for the continued support!

Thanks so much for the video!

@fordrac1ng81 4 жыл бұрын

Cooler temps and more red spectrum light will give them more purple color. Being on the bottom and not having lights under it to heat the tray as well as including more red spectrum, it's easy to see why the LEDs on the bottom gave different results.

We will have to switch up the lighting order to see! We're also about to start some experiments using different levels of yellow/red light to see what the impact is.

Lol, okay expert. The fans cost like 2 cents a day to run or something like that. They work great for preventing microclimates above the canopy of the crop. Get a big fan to move most of your air, then the small ones to prevent microclimates on each shelf.

@GrowingAnswers 4 жыл бұрын

Although in your case its not really a big deal, but you can't use a lux meter to compare lights that have different color temperatures. Lux meters measure mainly in the green part of the spectrum. There is actually a green gel over the sensor within the housing. So its very likely that your yellow looking LED's are actually putting out more umol than that what the lux meter can tell you. Essentially the lux meter is just measuring the intensity of the portion of the spectrum that the human eye is most sensitive to. Ex- If you measure a blurple led (pink, red/blue) with the lux meter it will give you a lower number while the actual intensity (umol) could potentially burn the plants with intense red light that the lux meter hardly measures. You really need a par meter to be fair when plants are involved.

@OnTheGrow 4 жыл бұрын

Totally agreed! This was just a slap together test to see what three very different lights could do to the growth of the same crop. We will eventually dig deeper into PAR and PPFD, but for now, we're just having fun.

@mackquack2929 2 жыл бұрын

LUX per watt is 269.6 for lower shelf, 129.6 for middle shelf. Grams per watt was 3.69 for lower shelf, 6.65 middle shelf. Considering the quality difference, I would probably go with the lower shelf lighting, especially for taller, longer growing plants. This would probably show a better weight to cost ratio.

@tim_koch14 Жыл бұрын

The strongest light could probably light twice the area it was used for in this experiment, so with a bit more distance to the plants, it could be the most cost-efficient.

I believe results for lowest most tray are skewed as all other trays have bottom heat from light below that seems to make quite a difference. Also high par also requires higher environmental temps to be most productive 83 to 85 for high par and below 80 for t5’s and middle rack leds

It was 15k for the decked out trailer, then about 5k in racks, lights, fans, dehumidifier, washer for spin dry and a lot of the supplies needed. All in about 20k. It could be done for much, much cheaper though. Buying a used trailer and converting it myself would’ve saved 5-10k at least. With microgreens, you could make that back in 3-4months with the growspace. Check out our website for more information about the space!

Florescent generates more heat than the LEDs. I personally use that heat. I use 4 tube grid lights recycled from a school relighting program. I drilled 1/4" holes every 4 inches in the diffuser. Then I mounted a computer fan in the light housing over a 4" hole I cut in the upper housing. The result is a diffuse gentle drying/heating breeze that keeps all mold issues gone! I only bottom water. Perfect combination of cheap, effective and easy. I recently started using 20watt led tube lights 3 to a shelf. They seem to produce slightly more light and far less heat. I grow in my basement year around. I think I will need the heat this winter. LEDs will not supply that. I have seen no difference in growth rates in my particular application. I also grow full size cherry tomatoes all winter. I use 2@ 4 tube florescent fixtures and 6 20 watt led tube lights, plus a led 40 watt dope light. In harvest tomatoes literally every day. New flowers, growth and have to bonzi cut every week. Tomatoes are very tasty. Nice video, thanks for sharing!
