Some great pics there Rolo. They look nice and healthy. I'd say you'll get a nice yeild out of that. Might be a bit tough getting 700 grams out of a 600 watt bulb though. From what I read, it seems alot of the more experienced growers on here get close to a gram per watt when using LST or a scrog system. If you can top that without using a scrog or LST, then dude, you are the man! Either way, I can't wait to see how these turn out. Keep it up! Keep posting those pics man.
