This means you can concentrate light directly on your plant. It would recieve almost all the lumens that the light emits. Basically light isnt lost; the plant receives all of it. No reflectors would be needed. Of course, there is a lot of adjustment and percision involved in setup, but it would be worth while. I'm not positive if this would work. Any ideas on this theory???
I don'tknow how to grow weed but I do know the physics.

You can't get any more energy out of the light bulb then what it what it already produces. If you want to conserve energy or increase intensity:
a. get a bulb with a higher :stoned: wattage
b. place plant and bulb in a box lined with tin foil.

if you used a magnifying glass your plant would end up like the stuff in your bowl, ash. That is unless you have it so the focal point of the glass is below the plant so that it dosen't scorch it. So one with a slight curve might work. Also glass will block all UV light.

Keep in mind that your plant is already limited to a certain efficency level so there is a point where increasing the intensity of the light will not make your plant grow any faster.
