Im planning on 3 plants and I have limited grow space. What the smallest tent size I should buy. 2x2, 3x3? Also whats the smallest height should I buy? The smaller the better. Its going in a closet.
3 plants? Depends on many things, but I have 4 plants in a 2x2, but it would be better with 3 plants. So I would say a 2x2 tent would be fine for most situations if you are only doing 3 plants.
