So the fan is placed above the lighting fixture, facing upwards? Is that right?

Does any1 know if there is any point in giving seedlings (1 week old) 24 hours of light with a 125w enviro? I think I've heard some where they don't even use this much at this stage. The lights are kept 2 inches away and they are growing nicely.

HI Gam,

A fan is most effective when it is pointed up toward the light from below. thus blowing the warm air up and away fro the canopy of the plants.

I'm using a 125w cfl 1 inch over tops with fan blowing in-between the gap. Temp about 25c. They grow quick and compact and look very healthy. Closer is better so long as the temps dont get to high, with blue cfl's you can get em 1 inch away, and the more lumens...well, yes. But lumens aint everything!

Thanks buddy! iloveyou!

Another Q for everybody, since we're getting into "bigger, badder" CFL's: Where can I get them? LOL I've tried homedepot.ca and shit and they only mostly support home lighting. If these big bad CFL's are actually cost-effective... well, Knowm, what's your standing on em?

Most places only sell 26W around here, max. Some, only 13. I'll have to hit up the professional supply in Kingston -_- All these fucking roadtrips....
