So everywhere i go on any forum i read about never putting more then one plant in the same pot. I haven't been able to find why its so bad. any links on info about this?
They compete for nutes and dont do as well. They will probably be ok together. A big problem could be if one is male and other is femaler. Then you risk ruining the female trying to cut the male away.
I'd also like to add that plant size is pretty much directly related to the size of the roots--so more space for roots to grow = bigger and most likely a more healthy plant. From the good ol' Grower's Bible. =)
