Using a reflector, your not gaining lumens... I dont think you have a clue what your talking about. All your doing is reflecting them back, so instead of wasting 90% of the light, thats not initially directly hitting the plant, that has to wait for something else to reflect it back, so you get worthless light from that pretty much, the farther light travels, its intensity just falls like a brick.
Using a reflector gives you about 8x more light hitting the plant [instead of wasted], and all about equally intense to what the bulb originally put out.
Lets say you measured light, just one example, put a 1200 lumen cfl above a light meter, hypothetically you get about 200 lumens. You add a reflector, and you will get upwards of 1000 - 1100 lumens, including light loss over the distance.
As for electical fires and anything... a bulb has no wires sticking out, I dont see a problem... it doesnt get too hot either, and I have the reflector touching the cfls. The only semi problem ive had, is one bulb started moistining up the adhesive on the duct tape, that attached the reflector to the can...
So anyways, with my 8 light strip cost me about $85, and I have 8 26watt cfls, I think they are 1700 lumens each, I give each one a reflector to save the light, that means I am getting about 13600 lumens, [my 1700 figure might be a bit off], and its takes 208watts. If I didnt use reflectors I wouldnt even be getting 1/5th of what I could potentially be getting.
Oh yeah, one more fun fact, the plants get most of its light from whats reflected, not from whats given out directly from the bulb... ask anyone.
but anyways
Day 56, Day 33 Flowering
[No Picture]
the plants are starting to look better, still no signs of sex, flowering could have been messed up sooo many times, but I took down the veg room it leaked too much light and all the sprouts died anyways. So finally the flowering plants get complete darkness for 12hrs. I think they were severly underwatered, after a heavy water they stopped drooping and perked right up.
