ok looked at your pics....no sunlight. i would suggest 2-1000 watt HPS if your going to grow trees.
seventhchild Reviewed by seventhchild on . Question about light set up / lumens / how many lights / Coverage?.... My green house pics are in my gallery. It's 9' long x 6' wide by 6' tall. I plan on redoing the roof to make it V in the center which is where the carbon filter and cooling hoses will go. Probably 8' tall in the center when finished. After researching it looks like I need to have around 150,000 lumens for optimal growth. (please verify) I was thinking of 3, 400 watt hps placed directly down the center of the roof width wise. One light per two plants and wrigging up some kind of pulley Rating: 5
