whats Strain would be best

Hey guys I have a grow space that is 2ft x 3ft x 5ft I am running two 60w cfl,
And a 400hps. I am about to pick up some seeds, I can put about 6 plants in the space but I
Think I'm just going to do 4 so that way they can spread and get enough light. So my question
Is what's strains are good producers that are good strong stuff I have limited space so I want to
Make the most of it.

It's not the number of plants per se, but how well you utilize the space. You could have one plant or six in there and either way, it could be a success or a failure. I used to have a space just that size. I started trying six plants, went to four then to two. I got better yields with two.

I would recommend that you go for plants which are mainly indicas with shorter flowering periods. Indicas tend to grow wider and rounder than sativas.

Most sativas can be anywhere from tall and round like a massive bush, to lean and spindly with a few large colas.

What strains do you have to choose from ? A smaller indica would be best. You could do 3 and if they get too big cull the least desired 1
