I am about to start growing in a 6ft. by 5ft. shed using a 4 by 4 tray and using a drip irrigation system. The tallest part of the shed is 5 feet. I was just wondering if a 1000 watt light would do good. If not what should i go with. It would be an aircooled hood. Also with only 5 feet inside what size plants would i be looking at. looking at putting in maybe 10-12 plants? Thanks.
