Are my expanding containers food secure? -https://youtu.be/kU891LPvEzc.
The white LED brand name is Roleadro. The Blurple light is 130 watts at the wall surface and also is common brand name.
I began the examination off with 6 gallons of water in the container as well as finished with a little over 3 gallons. The whole expand was over a duration of practically precisely 1 month in a constant ambient temperature level of 68F.
The PAR result was maintained under 300um of light at the plant cover with a brief duration of a little over 400um in the greatest areas, yet was changed swiftly. The PAR outcome on the lights was practically similar and also the facility PAR dimensions are 1000um/6″ – 400um/12″ – 200um/18″ on both lights.
The time gap electronic camera made use of was a Brinno TLC 200 Pro with the package lens. The evening cycle was eliminated in message as well as the staying clips were sped up in blog post by about 200%.

The white LED brand name is Roleadro. The Blurple light is 130 watts at the wall surface as well as is common brand name. The whole expand was over a duration of virtually specifically 1 month in a regular ambient temperature level of 68F.
The PAR result was maintained under 300um of light at the plant cover with a brief duration of a little over 400um in the highest possible areas, however was readjusted promptly. The PAR result on the lights was virtually similar as well as the facility PAR dimensions are 1000um/6″ – 400um/12″ – 200um/18″ on both lights.
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
Red also helps the plant development in root growth.
@Growing Answers lettuce tastes bitter when flowering
Why was such a objectively bad comment pinned?
@Tuned Gaming no one? Maybe not most people but I consume the flowers for their bitter effects. It helps my digestion.

White light has the full spectrum. I don’t know what the other lamp was, but red and blue are only specific frequencies. The plant will accept the full spectrum for sustenance except green. (That’s why most foliage is green – the middle frequency isn’t useful to plants.) It stands to reason white light is better.
“Red LEDs are less efficient“ and this dude calls himself growing answers?! Ouch! If the answers don’t need to be correct, this is your man.
I’ll save you time. Buy the white.
I don’t know about non-flowering produce, but I can tell you that flowering exotic herbals rock your cock under the infamous “blurple”.
ah yes for growing “lettuce”
Pseudo scientific approach does you no favours, way too many variables not addressed and ‘conclusions’ reached on very shaky data.
This isn’t a lab or a sales pitch.
to much N
I have used white light for years and mostly to start plants to set out in spring but bought red, blue, white unit two years ago to grow winter lettuce, it has worked well for me but I too believe the white gives a better result. I have one set up with a white 4 ‘, then a red, blue white mix in the middle, and another white and I switch trays around to account for discrepancy in light levels .
Wanna eat a bowl leaves?
This video is an excellent example of not allowing an exception to define the rule. When it comes to leafy greens, consumers usually prefer them to be less bitter and growers usually prefer a larger leafy biomass. However as many commenters have already noted, the denser rosettes and dark green leaves of the lettuce under the red blue light are highly indicative of healthier plants. Plants do not grow to suit humans’ purposes their nature is to grow as healthily as possible and reproduce under the given conditions. In this case under white light elongated leaves formed to absorb more of the usable light. As a result, the leaves contained more water and less nutrients. That being said, in regards to lettuce, this is often more sellable to humans for the purpose of consumption. Likely for the majority of consumable leafy greens with the exception of those grown specifically as bitter greens or to have a specific form like celery or romaine, this might be the best option. That being said, virtually any other form of vegetative growth where nutrient density, fruiting, and the overall plant health required to reach full productivity would more likely benefit from the tuned spectrum. It would be helpful to do a more thorough analysis of the leaves and to try this same experiment with vegetables that fruit or produce edible roots to see if these results hold.
If you didn’t already notice the age of this video and the fact that it’s part one of a series, I would suggest observing the results from the following videos and much of my videos that played into the future after this. Because that’s exactly what I’ve done over the years
Talk about seeing the light…lol! I would think white light does better, because it takes a rainbow of colors to make white light. And you used less energy and got more volume of growth.
same co2 ppm ?
They are in the same container and in the same space. It doesn’t get any more fair than that in that regard
Long time ago I was designing a harvesting robot arm for a bunch of NASA horticulturists growing broccoli and other plants for the first Martians. Only monochromatic light was used in the NASA biomass Chambers also.
So cool! I can’t wait to try this. Thanks for this 😊
