just got some wood to make a box. I am going to make it 4 feet tall. 5 feet long 2 feet deep. I plan on putting 10 plants inside 3-5 gallon buckets.... and using a 10o0watt light. I wanted to make it 5 ft tall but there was no 5x5 only 4x5's. Do you think im going to need to worry about it being only 4ft tall. i plan on getting this light system.help me out Tell me if this would be a good deal.
