When can I move light closer?

I made a new thread, because I don't know when it will be read...when can I move my light closer...I've been flowering for 7wks under CFLS' (approx. 19000lu) and just moved them to a HPS (approx 50000lu). I started them with the tops 2ft away, today...temp there is 78F...there were in higher heat before I moved the room and lights. They look good and all, just want to know if that was the proper height to start with...to me, it seems I can put my hand much closer to the light. (about 12 inches from hood it is about 88 with door closed, open it would be a little better)...

Well sorry for more q's....don't have much better than stress about them with this snow...lol...Thanks! :jointsmile: Bree

LoL, its horrible to be stuck in a room with a bunch or plants.

My plants range from 18-14 inches(1KHPS). The closer the better., put your thermo at canopy height so you can gauge the temps at the canopy level.

78F is canopy height right now, 2ft away from hood...sorry if I did not put that clearly...But from what you are saying, go ahead and move it a little closer, say 6 inches? I only have 4 hours til' nite nite, so I could probably catch it quick. B

woah, 4" is close. I hear 73-78 is optimum, but if you can keep it cool, 6" would be great..

mine have gotten in the 90's too(summer), but i'm sure it hurts the yield.

? I'm 24 inches from top right now.....? I wasn't going to go to 4inchs from top...lol. where did you get that? I'm 24 inches now, go ahead and try 18? still, laughing, although I might have read it wrong, i've had a few....lol

four hours was what time the lights go out......lol

LoL, now im laughing..yeah try 16-20 inches, maybe even 18...

Just check the temp after you move it after about 30 mins, to let the temp even out, a good scientest would wait about an hour.

Done, noted, and thank you, :jointsmile: Bree
