Magnifying Lenses To increase yeild

i agree with carcass91....have you ever burned an ant with a magnifying glass and the sun?..it would be the same concept...i've seen a bead of water act as a magnifying glass on a leaf of a plant with low wattage cfls and it left a burn

That is a perfect point, and the reason you shouldn't spray during light time..

the trichomes act as little magnifying glases for the plant. Thats why they are shaped like they are. Nature beat you to it.

we don't KNOW why they are there, it's all thoery

dude, U CANNOT CREATE ENERGY!

Law of conservation of energy states that " Energy can neither be created nor destroyed"

you said it yourself, he's trying to focus not creation

Archemedes focused light to burn enemy ships (maybe) and Natives in the americas used concave mirrors to start fires. In theory it would be possible to focus the light at the right intensity for growth.... The problems I see is little to no control of intensity, and the amount of distance you would need from the light to the lens to the plant works against the law of lumens....twice the distance equals half the lumens. you would probably have to do some major calculations to make sure you had it just right...like computer type calcs....you would also have to have this thing set up so that it could not move AT ALL (think on a track) or you would run the risk of A: loosing all the benefits you've worked and spent for or worse B: fry the plant, maybe literally BURN it.

All in all I can't see an upside to the work, risk, money, effort, time...but if you want to try I'd love to see the results

Trichromes will absorb damaging shorter energy photons while passing longer ones, and fluorescing some lower energy photons at the plant in the process.. Pretty similar to how glass blocks far more UVC than it does visible light etc..
Given response to more intense UV, and the obvious theoretical bonus I think its safe to say they are there for that purpose..
Again though, they aren't lenses, more like filters.. Similar to cheapo 3D glasses in principle (passing primarily red/blue light), but occurring outside the visible spectrum..

Hi m8,have u ever tried using a magnifying glass outside and concentrate it on the top of ur hand????? OUCH !!!
just imagine a 600w a coupkle feet away,there will b fires lol
thats wot i recon.im using mirrors in my room angling them slightly so the light reflects up from the bottom of the plant and is working gr8

Just so you know mirrors absorb as much light as they reflect, you might as well put a white piece of paper under your plants because it will be WAY WAY more effective than a mirror.

Why do you think no one lines their growroom walls with mirrors, its hella easy to clean mirrors. no so much for the mylar

well I did suggest the use of a projection lens i have. I have a HD lens and a floppy sort of over head lens.
