Ok, so I only pulled downed about nine zips from my outdoor grow! Know I want to go indoors. I have four 400w HPS. I only want to use two of them. I'm worried about having high utility bills. I've got the strains I want to grow down. Barneys Farm RED DIESEL, Greenhouse SUPER LEMON HAZE. And believe me when I say Red Diesel is the BOMB!! It's a heavy producer and super potent. Pulled downed 7 zips outdoors in a 5 gallon pot! My question is: How many TOTAL plants can I grow with two 400w HPS?? I plan on using a 400w mh conversion bulb during veg. How much do you think I can yeild? Whatt style of growing should I employ? (SOG, etc..) I'm growing organic in soil. Scared of hydro for now but plan on going deep water culture when I'm more comfortable and pockets are deeper. Thanx for your help GC. I'm living my dream.
