Oh sure, you can do 10gal. Only thing is less nutrient solution to work with, but 10gal is still perfectly fine :aok:
If you are in a 2 x 4 tent like you mentioned, even 10 gal totes are quite large...how big are they that you can get 4 in your space? Mine are 21 x 16 and I would only get 3 in my 2 x 4 space. Squeezing one more plant into a smaller space does not usually give you more bud. Overcrowded plants do produce less than spaces where the plants are not 'squeezed" in. I am thinking that 4 plants in that space start to finish are going to be overcrowded unless you are growing a smaller indica strain.
if you are starting from seeds and will flower them in there, then 4 plants would be overcrowded imo. i am able to do 6-7 small clones in that space but as THG mentioned, this doesn't give more bud, i just do it occasionally when my timing is off and i have to begin flowering. otherwise, it is better and easier to grow fewer bigger plants.
Or use the 2x4 for drying your bud?
