Thanks for the reply but I'm currently just limited to that space. I've got the walls and back of the door lined with Reflect-a-gro and I have a pulley system suspended from the top of the cupboard for the light fitting. Like I said, I don't really want to go overkill and want to keep the heat and running costs down to a reasonable level. I was thinking about rigging up 2 x 125w blue CFL bulbs side by side in the existing 2'x2' reflector I've got and then going to 2 x 125w Reds for flowering. Does that sound ok for the space? I was just going to go with one 125W but the lumens per sq ft is very minimal. I'd like to look at other set ups people have in the kind of space I've got if anybody can point me in the right direction?
