I think 3 oz per plant is definitely attainable depending on the light, grow area, and veg time. I actually saw a video that showed a single plant, ebb and flow system, in a 5 gallon bucket, with a Scrog screen above it, and there must have been 50-75 HUGE flowers, amazing. So depending on how much work you want to put in, 3 oz is simple,,, for a smaller, personal grow, check out www.thescrogbox.com :thumbsup:
