Just an Idea .....

Well imagine this . As I'm contemplating ideas on how I will upgrade my garden I was thinking on the thought of a circular led light . One that is 3-6 inches wide in the shape of a circle for the bottom of pots . The goal would to be 50w or less ( plugged in ) and light the growth underneath . I know I know . Popcorn bud usually turns out bad/small/trim bag stuff . What if someone used such a small device to lay down basically in 3-5 gallon pots and illuminate the entire bottom canopy with very little draw and making your bottom buds actually worthy of not being trim bag special . Again a thought . Any reasonable comments welcomed . I'm just curious if it would work . I'd be willing to give it a try on some clones .

I don't know if plants absorb light the same way as they do from above as for below the leaves. If it's not effective (having light under the leaves), side lighting may be a more suitable approach to your creativity. It works very well.

Agreed . I'd just think it'd be cool

they use to sell moving lights that would move from one side of your grow room to the other trying to hit all parts of the plant

popcorn gets a bad rap. Maybe for a large grower who has to pay workers to trim, but for the small grower, some studies show they can have increased thc. But you are correct, you need to get them light. There are just better ways to do it rather than adding a bunch of light bulbs.

Agreed . I'm just thinking a full very dense canopy situation maybe a lot of growers pack their tents with . I think it could be useful penetrating the bottom and top. Only speculation of course . Side lighting I agree is the way to go. Just thinking of possible ideas to maybe help out beyond the normal and good practices we all strive to do

well damn everyone like increased thc . I'm just thinking of eliminating popcorn through a small device and up the yield for everybody . May even stop low-light hermies from forming ,???

easier to make the plant adapt to the light, than inventing new lights to adapt to new plants.

Thanks. The directional light of led makes them exceptional for getting light right on target. The light chamber idea isn't a new one but until recently it had to be done with omnidirectional light sources which needed reflectors and made too much heat. With led the dream is achievable. I won't get specific but the yields have been amazing for 6 square feet or maybe I should call it 12-18 cubic feet.

Hello,

I'm persuaded that the side led lighting is the way to go, the light repartition might be ideal that way ...
and your setup show that it works great

but there's still something I'm wondering about, I was always told that leaves drive better photosynthesis with perpendicular incident light
my question is: is there a point to provide light to bud ? seems like a very silly question :eyesmoke:
mean to light buds instead of leaves

any thoughts about this ?

I haven't read that about the perpendicular angle but it makes sense. I do know that lighting the bottom of the leaves isn't productive though. My sidelighting is all at a ~45 degree angle to the plants. With that light totally surrounding the crop everything gets light mostly to the top surfaces of the leaves. The bottom of the plant will produce similar to the top as long as it get a similar quantity of light.

That's awesome! I did this once with 8' fluoro shop lights and was surprised at how effective that style of lighting is, even with the low power and intensity.

I've seen a 50% increase in yields over when I used top lighting only. For every gram I got with top lighting alone, with side lighting I get 1.5 grams. This is in the same size space and using and the same amount of power.

well then, it's really a new topic isn't it?

Side Lighting

what was that box they use to advertise in High Times that had the fluorescent lights all up the side?

cree and led make side lighting more accessible

to a previous poster with a question, Yes, they have done experiments shining light on buds that were previously shaded and noticed an increase in the size of the bud, rather dramatically, rather quickly.

If you didn't care how long it takes and were willing to wait forever, there are growing techniques that will put each bud in direct light using just one overhead light. But nowadays you can just about put an led on every bud.
