600w hood users

you all get plenty of bud density at 18 inches? enough light to see good results with co2 @ 18 inches?

after reading the OLH is 18 it just seems so far away =P

mine is not aircooled but with fans and glass in the hood, i can keep it around 10-12 inches from tops without any issues

I keep my cooltube about 8 inches away with no problems at all.

I have a couple of 600 watt bulbs in cooled hoods and I can get about 4" away. I have a 400+ fan pulling the heat out through 6" ducting and a few fans to prevent burning.
