and that is not based in fact so if you have ever put that kinda of light density to the gurls with cfl's tell we what is true..

and HID does rock.. even a n00b can get results under a HPS..

MG, don't worry about the watts so much. watts are merely the consumption of power. 400W of HPS compared to 400W of CFL is not the same. true it's both 400W of power being consumed, but the difference is that one is more efficient than the other. the CFL produces 46-72 lm/W (or is 8-11% efficient). a HPS is in the 85-100 lm/W range (or is 12-22% efficient). granted lumens are a measurement used for the human eye.

not to mention, the lumens, ~1600 for a 23-26W CFL are not added together. they do increase in areas where the light overlaps, but it's not like you (and most others) are thinking.

lets say you had 50 CFL bulbs (all 1600 lumens).

1600*50= 80,000 lumens (IF they added up, which they don't).

now a 400W HPS ranges from 50,000-80,000 lumens....all from a single light source. therefore you know that you are in fact getting said lumens.

did that make any sense?

not to mention, that's ONE plant. under how many CFLs? that one plant's meds aren't gonna last you very long (although this is relative) as a tent full of bigger, more dense buds that more than likely have better trich production. not to mention you will spend less on a HPS setup in the log run as opposed to adding more and more CFLs. trust me, not getting an HID off the bad is the single biggest mistake most people (including me!) make.



MB, i was in no way knocking your plant or anything. she is a real beaut! i've worked under CFLs for several grows and just outputting my opinion from my knowledge gained.

keep up the amazing work!
