Hey, I'm about to make this happen (credit card in hand), and I need some opinions. I'm going with a Gorilla tent. I don't want to fuck around with quality, so that's that. I only want to grow enough herb for myself. Two plants, MAX. Scrog style. I want a larger tent because I'd like to keep the smell contained while having the elbow room to tend the plant. 2 x 4, 3 x 3, or 4 x 4? The price difference is rather large @ $70+. If it were you, would 8-9 sqft be enough to grow your two plants? 16 too big? What is optimal? Does optimal exist? Thanks.
