....my maths wrong???...how ya figure?...different namebrand cfls vary on actual Watts and equivalent Watts....I can read what my box says....anyway...zero is ur answer...zero grams is what you'll receive from a "foil" lined box of that size with so little lumens....not enoughI gotta tell ya ur math is all wrong and I just wanna know in grams how much I could get. also how much did u get from that?
.....I read somewhere the standard is 30,000 lumens for a box that size to have a successful grow...that's what I tried to shoot for....4 of those 23watters is like 6,000 lumens....they're like 1500 or 1600 a piece....u need at least that per plant........I have a little more than that and am gonna add a few when flowereing...Ive already taken into account the incandescent equivalent, C maybe thats why their was confusion but Im using 23 watt cfls which are equivalent to 100w. Now i did use incandescents before and I got like 12g.... never gonna do that again.
