Are my growing containers food safe? -https://youtu.be/kU891LPvEzc
The white LED brand is Roleadro. It is 115 watts at the wall. The Blurple light is 130 watts at the wall and is generic brand. Info for these lights can be found in the links below.
I used the nutrient trio from General Hydroponics. I started off with a seedling dose and then jumped to the aggressive vegetative dose after the plants had their first few sets of true leaves. I started the test off with 6 gallons of water in the container and ended with a little over 3 gallons. The entire grow was over a period of almost exactly 1 month in a consistent ambient temperature of 68F.
The PAR output was kept under 300um of light at the plant canopy with a short period of slightly over 400um in the highest spots, but was adjusted quickly. This is when the minor tip burn occurred. The PAR output on the lights was almost identical and the center PAR measurements are 1000um/6″ – 400um/12″ – 200um/18″ on both lights. The type of lettuce was “Black Seeded Simpson” from Burpee.
The time lapse camera used was a Brinno TLC 200 Pro with the kit lens. 1 photo every ten minutes. The night cycle was removed in post and the remaining clips were sped up in post by roughly 200%. If you look closely you can see most of the growth actually happens at night. The lighting hours were 17 on.

I give plants both lights and don’t have any problems
So simple white LED Is enough?
The only thing this video left me slightly curious about was the nutrition content of the lettuce. I’m wondering, with the different coloration between the two groups, if the red/blue light lettuce was more nutritionally dense than the white light lettuce.
Considering you grew lettuce which does NOT flower or produce fruit… its perfectly logical that it DOESNT need red light which is important for flowering and "fruiting"and not vegetation and most full spectrum leds have 60-70% of red led diodes… Just saying.. You should do some fruit grow actually … If you did send a link
I would expect more vegetative growth under the predominantly white light. The red spectrum is for flowering or fruit production.
WITH SOIL AND SUNSHINE IT IS STILL THE BEST SOLUTION…
GO BACK TO THE BASICS
Thanks for really shining a light on this topic.
super helpful sir!
There are photosensitive proteins in plants – each sensitive to different wave-lengths. Daylight is a bit "colder" (has more blue) than dusk, for example (which has more red). Red-sensitive proteins (phytochromes) are at work (they carry signals that make metabolic changes in plants) mostly when red light is in excess. Blue-sensitive proteins (cryptochromes) are at work when blue light is in excess. So, you see, it’s not that the process of flowering or fruiting its self "needs" a certain type of light. It’s just that certain types of light are dominating at different times of day, thus creating a rhythm for the plant. Shorter days mean less time exposed to blue light, which means there’s less time for cryptochromes to affect plant metabolism. That in turn signals to the plant that it’s time to procreate because shorter days mean an end to summer which in turn means winter is coming. So, you see, plants use blue/red light to sense time and adjust their own metabolism or focus of life force. This is such a meaningless test – you need different time schedules if you’re using different wavelengths. Not to mention that using the same container, and the same nutrition is also a red flag for this "experiment". All this experiment shows is that the conditions set by its parameters is more favourable for growing lettuce using "white" LED light sources (wtf is WHITE – 6000K? 6500K?). Totally meaningless. Any grower would see this as laughable clickbait.
So all those expensive grow Lights are just bullshit
Very informative 👍
what do you feed for plant growth
What is the height in between level sir?
Fun fact. The sun gives the most energy in green color, that’s why plants are green, the second in quantity is yellow, that’s why We are a bit yellow.
Great Video! Any advice on planting cherries, Mango, and peaches ?
Nice. I would be interested to see what the ‘dry mass’ was of both types also. I was thinking that the white light plants may have more water content – perhaps larger or less compact cells and the bitter taste of the RGB plants may be as a result of this. Liked the experiment – well done.
30%blue 30% red 40% phosphors coated blue LED’s have had pretty good results for me with tight node’s and 4-6 hours of supplemented UVA goes a long way
thanks for the video, I will use red light
The higher percentage of blue light in your RB led is the reason of higher chlorophyll compared to the RGB led 😉 and blue surpresses leave extension so the leaves were less elongated than RGB because of that, despite the same amount of red.
"I didn’t grow plants…I grew answers."….instant sub.
So those red blue light led are just gimmicks
how far are the growlights to you growbox?
Hai, I just wondering if use for flower plant which one is better, White led or red blue LED?
Sub freakin scribed!!!!!!
I’ve never seen
grams measured with lettuce 🥬 the world is changing 🤔
1:44 I have the exact same place mat as you, how odd.
I am so glad I saw this before unpacking my new red & blue lights!
Thank you for the scientific analogy
Did he said red-blue light tasted better or bitter?
🥰😍 I Love you😍🥰
i have both lamp types. The one with red, blue lights seem to grow smaller size, but the leafes look amazing and the plant in general looks healthy. The leafes look much darker and healther, there is stronger smell and taste to plants from under red blue light. I dont knwo what light produce more yeild. My red blue light is only 70 watt, while the white light is 300 watts, so this is hard for me to compare, but when it comes to smell, taste and healthiness of the plant, red, blue lights win.
People going really in depth with comments about white vs red blue ect, fun fact white lights produce all spectrums of colour just because you don’t see them dose not mean they are not there, hence our own sun produces gama rays UV rays UR and vitimans so please be aware what ever you know, you may just be reading what you leartlnt not what the facts are, I will even say that someone will comment bellow me stating I’m wrong but to the best of my knowledge I have informed here is fact and study worthy, on that note I don’t know much about these HD lights but still white lights produce many spectrums so please read manufacturing labels and not the retail details
Thank you for sharing your results.😊
I always wondered if there was a difference between the two.
Even on Facebook forums they couldn’t give me a answer.
But now a question.. is there a difference in a full spectrum light, red-bleu light, or the white light?
Hi, that lD for sharing your experiment. I would like to know what is the best choice of LED color temperature for vertical gardens?!!
mate you’re getting a sub
Thank you for posting this effective comparison video. There’s a lot of not-helpful ones out there.
Nice timelaps test even though it’s well known by now that plants perform better with a full spectrum white like the sun (kind of a no-brainer).Blurpals should only be used for disco party’s Imo?
Thank you for taking the time to do this cool video.
you saved me from making an unnecessary expense
But your honour i thought it was lettuce
open 24 hours?…???
Best spectrum for grow leaf with Blue Led..
Great video! Now I can make a better choice to grow my…uh…lettuce…yes, just lettuce
Wow great video thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I just germinated seeds in hours, put some pepper, tomato and broccoli seeds in a brown napkin yesterday. I’ve got them in soil two weeks and nothing yet but I’m ready. I put in paper towel to make sure viable and broccoli and peppers already popping tails…yay!!!
This video gave me ideas.. Thanks sir 👍
What iş the temperuture of colour
Ah, but, which has the highest nutrient value?
RED & BLUE LIGHTS ARE FOR FLOWERING PURPOSES… LETTUCE IS THE WRONG VEGETABLE FOR THIS EXPERIMENT🤥
