Good luck to ya on your harvest, I can't wait to see how you do.

I read about a guy who's using some of the really big CFLs - have you thought of that for your grow?

i'm using smaller CFL's (mostly 40 watters) partly because they're so much easier to find, they're way cheaper than the big ones and, maybe more importantly, the smaller bulbs allow much more flexibility when it comes to tweaking your light spectrums.
for example, a 200 watt, 6500Kelvin bulb will never be anything but 200 watts of 6500K light. on the other hand, 5 x 40 watt bulbs can be split between spectrums so you can add some reds as well.
anyway, that's my reasoning, whether it makes an appreciable difference in yield remains to be seen. lol

so, toke amongst your selves
