The actual space for the plants themselves was 1x2 meters on the floor by 1 meter high- and it was too small. They grew right up into the lights and fried. I had to swap out the HIDs for tube flouros and limp them to a pathetic harvest. You're gonna spend more than the equivalent of 500 USD just to make the place useable, and it's not worth it.
Why can't you grow in your house? That's the logical solution....
Balls! it doesnt look good then!...I would ideally grow in the house but my wife is keen to keep it external. will work on that one.

Thanks stinkyattic
