I know it should be 2 just so the roots don't get tangled but I wanna do 3 just so theres a bigger chance one of them is female. I have limited growing space so yeah.The planter is 2 x .5 x .5 ft large.
I would put at max 2,maybe 3,bearing in mind over all yield will be the same 1 plant would get larger, but yield less than 2 though, though see what other people say too
