I have 4 plants. These ones are vibrant. Day 13

Day 13 also these are Auto's. I tried before in soil and failed with them. You can't miss a beat with Auto's or you get more less nothing from them it seems. Gotta be perfect or close to it. I won't grow Auto's again.

have ceiling fan, oscillating fan, small fan run all time.When plants larger will the size of room be enough without ventilation? 17' x 8'
