Its already driving me nuts it so dark and cloudy!!!
What would you do?
I have 2 -Worms Way 400 watt metal halide light fixtures im not using and want to know if i should hang them in the GH?
What distance from the lights is safe for multi paphs? I have and do grown many other plants under HPS/MH but not paphs.(basement) How long do i run them in a GH with a lot of Catts? Any other ideas tips? How close to the roof is safe?
Thanks for the help!

I don't have a greenhouse, I grow indoors under HPS lights but if I did have a greenhouse, I would probably put it on a timer and set it to run at least 4 hours from 2pm - 6pm daily. But what about cloudy days? :confused: I have no greenhouse experience, so hopefully one of our members with greenhouses can weigh in!
