Hi, so I have exactly the same tent from Spider Farmer. I either have 6 autos in 15-20 liters or 3 photos in 50 liters, but currently, I have 4 photos, 2 in 50 and 2 in the 20-liter pots. I wouldn't do more than 4 to make sure there's still enough space. If you want, you can check out week 16 of my eleven Roses clones; there's a picture of the whole tent there.
