i got a hood with my light & ballast that was an 'ablite' like an adjustable 'batwing' one but was rigid & one piece( picture here ) . My grow room wasn't cool enough in the first run, it wasn't critical, but i wanted to lower the temps. So i made this air cooled hood and am changing my idea from an active exaust system to a passive intake arrangement. pic .......

Hey guys Even though I’ve seen different seeds grow and smoked them from sensi seeds to xxx serise seeds and whatever. I’ve never attempted my own grow before. now that I am moving out into my own place with a room mate, I only have a 8 by 10 room to grow possibly a bit bigger then that so I don’t have allot of room and I am going to need to grow inside a closet space as the room will be my bedroom so heat is going to be a problem what can I do to reduce the heat off Sodium bulb’s in my closet space . Also is it true what they say about color fluro's flights in growing or is it just a myth? cheers Cronic

My cupboard measures 1200 wide an 600 deep it has a light rail of about 700 an an air cooled hood, I run an air-con for most (not all) of the time as I live in Darwin woohoo Mozz

There seems to be some debate about when the exact time to change the globes used in the growroom. I am not too sure about this, I have heard change it every 3 months, change it every 6 months, and some that say dont bother changing it for a couple of years as the loss in lumens isnt really going to affect the plant....provided u start with a decent globe such as the phillips in the first place..... BY this I mean 3 months worth of usage etc.... Anyone got any ideas?
