CHEAP LEDs vs GROW LEDs - Microgreens - Rambo Radish - On The Grow

[@storytimeforkids8694]

Hey guys! My husband and I are starting an indoor microgreen farm in Sanger, TX, and I just wanted to say that your videos have been an incredible source of information for our start-up. Thank you so much for the wonderful information that you share.

[@OnTheGrow]

Thank you so much for sharing and your support! Excited to hear how your journey goes!

[@OnTheGrow]

**The 42 watt LED's are T8, not T5 like I listed in the video. My Bad! All future videos will be corrected, sorry about any confusion this may have caused!**

[@robertm4050]

Do the T8 and T5 even matter anymore, now that they are LED? It isn't like they run on a ballast like flourescent bulbs and the T--- followed by a number only means the width of the bulb. I don't know why they continue to use that information other than which new bulbs fit in what fixtures, but there are not many fixtures T8 and larger.

[@OnTheGrow]

Agreed! That’s why I assumed they were all T5... the T8’s are slightly thicker, but just barely compared to the T5. Like you said too, they don’t need the ballasts anymore so not sure why it’s broken into those classes still.

[@DM-dq9do]

Probably to give it an equivalent

[@dspiritualone5414]

So the link in the description to the T5 lights are not the ones you are using in the video?

[@OnTheGrow]

@@dspiritualone5414 The link in the description is correct! It is simply the text for the T8's in the video that is incorrect.

[@tmattler4606]

I use all of these same Barrina lights on my grow shelves. In testing these lights I found that the PAR output of the cheapest lights was more than doubled by removing the frosted plastic diffuser. Doing so voids the warranty of course, but I now routinely remove the diffusers from all the lights that have a frosted diffuser. Also, the blurple lights ship with optional reflectors. Using the reflectors significantly increases the PAR output of the blurples.

[@OnTheGrow]

I will try the reflectors on the next set of tests! I have been waiting to pull the diffusers off until I finish the current experiments. I am going to do that and see how the 3 non-diffuser compares to the 6 with diffusers. Should be cool! Thanks for the suggestion!

[@gregfee1120]

trying to chase down these pinkish lights, but having trouble finding, Barrina, 42W, can only find the magenta grow lights, do you have a link or are they no longer supplying? thanks, good tip on removing diffusers... greg . homegrownmicrogreens

Grateful you asked, because then I knew to include it!

@@OnTheGrow Glad you did. I just couldn't see the distance in the video so I thought maybe you didn't know. I am sure you get plenty of comments like that on your videos. But it is good to add it to the videos and if I can make a suggestion.... Maybe add the reason you discuss the distance to the light, so people know for their own purposes. Not everyone knows that the distance to the light can greatly effect the growth. Thanks for the reply.

[@mofomoco]

@@robertm4050 what would you say is the perfect distance for my lights to be from my plants? I have them pretty high (12" or so) above plants right now but they seem to grow fine.

[@robertm4050]

@@mofomoco I would say less than 6 inches, but older bulbs can get really hot so you may want more distance. Higher end bulbs don't need to be as close as the cheaper newer ones. You might want to look at the directions that came with your light.

Though this video may be too years old, this iVERY helpful to smaller (and old enough to be your parents!) food-for-family growers. REALLY appreciate the steps you took to more closely follow a scientific experiment process which brings to much more validity to the content! I did read about some quality issues with the clips and switches in a few of the Amazon reviews. Do you have updates or additional info about these concerns after long-term use of the cheapest (and best for folks like us in particular) Barrina lights used on shelves 1& 2?

[@geriforsythe1165]

This is the first video of yours I have seen. Really appreciated your candor during the entire process. I am looking to grow just for my family and felt I got a good foundation regarding grow lights. Thank you. (look forward to more of your videos)

[@lilikays6528]

This is the most informative video on lights. Thank you

[@stitchergary]

Yours and many other KZbinrs motivated me to try microgreens and DWC... Bought a bunch of supplies, seeds, lights, etc... Just started my first seeds a few days ago.... As I'm setting up my shelf and got thinking that aluminum foil would reflect light more on the plants... I see you don't have anything around your shelves.. Is it better to keep it open for better air movement???? thanks for all the time both of you put into these videos.... Your grow area always looks so clean....

[@8Razer882]

In my opinion preventing mold with better airflow is more desireable than yielding more due to more lightpenetration. But if u still want to test with reflecting light then u should use a white foil or something like that because white light reflects better than the aluminium foil. i hope you´re having a great yield :) happy growing

[@OnTheGrow]

Thank you so much for the support! We do like to keep our shelves opened so that there is no interruption with the airflow. When we first started, we had bad air-flow which caused a lot of issues... There is a little reflection on the top of each shelf... There is a reflective foil layer to help bounce some of the light down. Also, that back wall is great at reflecting some light back. That is really it though. I’d choose good airflow over trying to reflect a bit more light... You could leave just the ends open and cover the front and rear. That sounds like it would help to reflect and keep airflow, but I haven’t tried it yet! Thank you so much for your support!

[@extendedp1]

That was an awesome video, thanks. Subbed.

[@OnTheGrow]

Thanks for the sub! We're glad you enjoyed it!

[@MrWillman49er]

Hi, really enjoying these videos. Are the lights on the top two shelves just normal LED lights, ie not specifically designed for growing. Cheers.

[@MetalDetectingChannel]

Curious if the lights affect the nutrient output?

[@UnlistedYoutubeVideo]

This is like the best video ever. Getting started is expensive and tour videos help people who are less fortunate not waste their little budget. Please buy reputable brand expensive lights and show us if they’re worth it. The yellow and blue strong af high par lights u have r the best and i wouldve boughten either but theyre not available of course. Seeing least expensive vs most expensive is imperative i think. Because Its mind blowing the results you can get by making upgrades.

[@angelasandlin7058]

Thank you for doing this video.☺️ I have just begun to learn about growing micro greens. I’m setting things up in a closet inside my apartment. I have been stuck on which lights to purchase. Your video just removed my guess work, and I am grateful. Again, thank you ! Looking forward to your next video.

[@OnTheGrow]

Thank you so much for your support Angela! Excited tied to hear how your first grows are going!!

[@briankathy2580]

Love the way you share your result with others, please keep the vid’s coming - With reference to a comment made by mnelson 10000 i.e. “half the running cost and not too far behind in yield”: I don’t use lights to grow micro greens but I do use them to produce seedlings. Like many other growers, I have found that being able to adjust the height of the grow lights pays dividends in producing healthy seedlings, especially with a cheaper lighting set up. I appreciate that your setup is fixed and not easy to alter but you could try an experiment, via raising the height of each tray under your cheap LED set up, with wooden supports of various sizes, 2x1, 2x2, 2x3 lengths, etc. to increase the “PAR”. Just a thought that may (or may not?) improve the quality / yield of your product, at “half the running cost”, with the cheap LED’s.

[@mnelson10000]

Very nice! It's interesting that even though the bottom three had the highest yield, the profit margin on the top shelf totally blows away the other three... half the running cost and not too far behind in yield. The equipment cost was much lower, too. As far as appearance difference, another day of growth may have mitigated that.

[@OnTheGrow]

We completely agree! It's pretty amazing what the three 20watt LED's can do in terms of growth for cost. As you upgrade you operation, you can easily add more lights to each shelf if needed.

[@Steve_Van777]

Quality over quantity for me.

[@johnlapp41]

The cost was for electricity only I believe, not the seeds, mat, and time. All of which were the same so really the total cost is only pennies difference.

[@LeslieWorks]

one thing i'm concerned about in this test is the light leakage going downward to the other trays, for example if you put the top trays and lights on the bottom, would the result be the same given that those plants would now be getting light leaked from the above levels. just a thought.

[@goodgoat3096]

The PAR meter only measures visible light and not ultraviolet (UV) and infrared (IR), both of which can be beneficial to plant growth. This shows in the results in that the blurple light had the highest yield but the second lowest PAR measurement. The blurple lights are not really full spectrum but actually multi spectrum and have fallen out of favor, at least with growers of "medicinal" plants, as problems with plants are harder to detect under the pinkish light. An interesting test would be to duplicate this test but with white lamps of equal wattage with color temperatures of 6500K, 5000K, 3500K, and 2700K. The lower the K number, the higher the amount of red in the light spectrum. Great channel and nice comparison tests, keep it up.

[@ashtanga2000]

yeah, quantum boards are current tech. But, may be overkill for microgreens.

[@goodgoat3096]

@@ashtanga2000 - The Quantum boards in this case would be overkill. Digikey sells LED printed circuit board arrays from Samsung, Seoul, and Bridgelux. They are available in lengths if 280 mm, 560 mm, & 1120 mm, or roughly 11", 22", & 44" and in widths of around an inch. The Quantum boards use the Samsung 561 or now 301b LEDs as do these Samsung strips. These arrays are also available in several color temperatures and are extremely efficient providing from 140 to 200+ lumen per watt. The inexpensive LED shop lights that I use for starting vegetables provide only 112 lumen per watt. A diy'er could easily make super efficient LED grow lamps suitable for micro greens using these parts. The expensive parts are the constant curremt power supplies and potentially required aluminum heat sinks The electric bill is a factor to be considered for commercial micro green or other growers.

[@OnTheGrow]

Thanks for the support! We are actually about to start a test where we use a light that can operate in different temperatures and we are going to compare what your suggesting! It will be 6500K, 5000k and 3500K I believe. It only has three modes so we will see how it turns out!

Again, big thanks from us here in Myrtle Beach. Keep rocking on CJ & Mandi 🤙🏼. -Oscar

[@OnTheGrow]

I’d suggest the Barrina T8’s over the T5’s for indoor growth the the flowering stage... we have grown to the full flowering stage in the past with the T5’s and they did a good job, but they will definitely cause a bit more stretching... I’m pretty sure we used 4 of the 20-watt T5’s for our indoor edible garden system. I’d swap that with three of the 40watt T8’s in the 5000k spectrum and that would likely do the trick!

The LUX measurement is down to a few hundred in the afternoon. Should I move it to under a grow light when the window does not have bright indirect light ?

As for reflecting, we turned all the lights on, one-by-one and looked at the light passing to the shelf below and it is very minor. There is opaque layers in between each shelf and the rack is placed so close to the wall that only about an inch of light passes onto the wall to the shelf below it... if that makes sense.

I'm no plant scientist, but it looks like that meter is measuring PPFD. PAR is a range of wavelengths that are photosynthetically active from my understanding--it is specific to the plants chlorophyll systems and would not easily be measured. The units expressed are those of PPFD, micromoles per square meter per second. PPFD is measuring the PAR flux density. Please correct if wrong.

[@joshoooway]

Did you get an answer or confirmation to this realization?

[@seanwelding4183]

I can't seem to find the pink Barrina lights on the bottom. You said they're t5's and all I find that is actually full spectrum are t8's from that brand. You have only the Blurple bulbs listed in your Amazon store and those are also t8's. If you could update your store I'd really appreciate it. Thanks so much for the video!

[@OnTheGrow]

Hey Sean, apologies on this, I made a typo. The two 42watt LED's are T8's not T5's like I list in the video. I will update the coming videos to have the correct class. I'll see if I can add a correction in this video. The two T8's in our storefront are the same used in the video. Sorry about any confusion!

[@seanwelding4183]

@@OnTheGrow No worries. Thanks for clarifying! I'll be sure to pick those pink lights up here soon. I very much appreciate your reply.

[@KonigKriegD]

Did you find a difference in flavor? We were using 4 of the blurple style barrinas and found our greens were way too potent in flavor and everything started showing true leafs really quick. We just dropped down to 2 a shelf to see if we get a slightly softer flavor from our greens. And your costs, is that per day, per tray? Or Per tray total?

[@KonigKriegD]

Sorry, just got to the flavor part! I would recommend cleaning your palet with something designed for it to get a better comparison between trays. Just a suggestion. And good for you eating so much radish first thing in the morning!

I bough a 6500k 2400 lumen light (4 of them) these are tube lights with a milky diffuser in the front. Will diffuser create any problems ?

yes remove it for better performance

Hey Guys, is there any other Brand or LED light setup you can recommend? It needs to be 120 cm wide and accessible in Europ, in best case scenario Germany :-) I was thinking about the MARS HYDRO LED Grow Lampe SP 250, but it might be to mutch for growing microgreens.

[@pold5993]

Hello m8, which sensor is that (it looks like the old one)? Also, it is ppfd not par.This is what you want to study the most as indoor grower - the light.Cheers!

[@OnTheGrow]

The owner of the Apogee company referred to the measured units it as PAR so I followed his lead! Here’s the one we got: www.amazon.com/gp/product/B07Q2C8C1P/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

[@allenriley6886]

Would the 6500k make a difference because I have 4000k

[@OnTheGrow]

🙂We suggest using Three 20watt T5 LED’s per shelf. We look for a minimum of 6,000 lumens per shelf. We have used these for a while with great success www.amazon.com/dp/B07F2WMCP2?tag=onamzonthegro-20&linkCode=ic5&ascsubtag=amzn1.infl.us.product&creativeASIN=B07F2WMCP2&ref=exp_onthegrowfarms_dp_vv_d

[@Mickimoss]

This experiment really makes me want to use sunlight than lamps. Because sun is crazy powerful, I test using doggo lux meter for android and the result is insane, my t5 18watt 120cm light setups only give 1300 lux (1 lamp), 2500 lux ( 2 lamps), 4600 (3 lamps). while outdoor sun can range between 4000-10000 , direct sunlight is insane 120,000-140,000 while being so far away, nothing beats sun. I just need to make a small tabletop greenhouse for it.

Thank you for your support!!

[@RovingPunster]

Comment: you neglected to mention the length of the bulbs (guess: 4ft ?), and you seem to omit the cost of the strips/ballasts from some or all of the lights. Buying grow lights isnt just about the bulbs - they dont work without the correct ballasts. Anyway, It would be helpful if you included all this info in future comparisons, just for completeness. Aside from that, THANK YOU - ive been learning a lot from you guys. Cheers and +1.

[@OnTheGrow]

The ballast are included in these, they are 4ft and we list all items in the description with direct links so you can see all the details. We try to include as many details in the video without it becoming too much. Hope that helps!

[@RovingPunster]

Apologies ... I got confused between different brands on amazon unbundling lights from ballasts. Question ... So, I have a pair of Active Grow T5 23w in my shopping cart, but I was wondering ... In the vid you use 2 per 18d x 48w shelf. Is 2 ideal, or would 3 per shelf be better ? How much lux is optimal vs too much of a good thing ? I'm putting together my 1st grow rack, so this is timely.

[@OnTheGrow]

@@RovingPunster great question! I'd suggest around 60 watts or 1200 lux per shelf as the minimum. We aim to get 60-100 PAR We like to run 3 x 40 watt LEDs like these : a.co/d/c6aNt4A We find the stronger light adds more coloration and you don't need to run the lights as long.

The bottom ones are 42w or 24w? 20 $ is too cheap for that wattage. The Amazon link is says 24w

[@OnTheGrow]

42watt. They pull 41 actual and do a pretty great job!

[@zackmoss369]

So, I think the grow lights are actually the T-8 lights from Barrina - their T-8 grow lights are labelled as 42 watts each, their T-5 grow lights are labelled 20 watt each. Which is confusing, since in flourescent lights, T-5's are brighter than T-8's... I guess with LEDs it's just determined by how many diodes they can stuff in the tube, and the T8 tubes are bigger, so more LED's? Apparently.

[@sharriceowens913]

It would have been nice to see how fluorescent lights compared

[@OnTheGrow]

We have a test coming soon where we put the fluorescent against 3 different LEDs!

[@sarcasmjkeee]

Have you tried 5000K and 4000K temperatures?

[@OnTheGrow]

I have tried 5000K and it worked well! I have not compared them side-by-side with other spectrums yet though. I just got some in so that I can test 3500K vs 5000K vs 6500K

[@weswatkins6363]

awesome. i look forward to the test. peace.

[@bushylingus6272]

Blurple ain't full spectrum or is the sun blurple.

[@OnTheGrow]

...the manufacturer referred to it as full spectrum meaning that it encompasses many different light spectrums that cater towards plant growth.

Loving the content, want to let you know your Amazon On The Grow page the seeds you recommend from Sprout House are all unavailable. Do you have another seed recommendation or location to purchase? TY & Subscribing!

[@kenabisan4731]

The problem with cheap leds are their lumen will decrease drasticly over time, way way faster than the expensive ones. At the end you safe money buying the expensive ones, i guess.

[@OnTheGrow]

We haven’t noticed any substation degradation in the lid output… we’ve used some for over two years, every day, 17 hours a day and they still have similar luck output to day 1… even their PAR has stayed similar.
