I agree with the beginning off this thread where everyone said to seperate them. it seems like as i read down the opinions to swith them out or leave them began to lean more towards "leave them theyll be fine together" ...well consider this.
-How would you transplant if theyre roots are entangled.
-If you have a female and male nest to each other I would think thats a good chance of pollination... which isnt good unless your goin for a seed bank
-Same case scenario: Male and Female in the same pot with theyre roots together, if you choose too. how do you remove the male roots and not the females?
-What if one grows tall while the other is short, that might cause problems as far as the light distance
I could probably go on... But at the same time, feminized seeds would cut the risk in half at least.. and if they are feminized and auto flower (which i doubt?) i would then say go for it... But if not those are my opinions.
