I'd separate the two in one pot ASAP, in a week you may not be able to. The way I do it: first get another pot ready(fill at least halfway with new mixed soil whatever you use), take the existing pot, roll your hands on the sides slowly (makes it easier/looser to get the dirt/roots out of pot) flip over holding the stem and dirt; the whole dirt/root mass should slide out of the pot, carefully separate the two into halves (you're gonna break roots, just be careful)then repot them, give a little water with no ferts and watch em' droop for a few days, if you wait the roots are gonna be bigger and the plant is too, so now is the best time.

transplanting is *always* scary unless you've done it a 1000 times(I'm not to that point yet myself), again be careful!
4x5 Reviewed by 4x5 on . Growcab update... Thought I'd get a little input from you expertz. I just added a 1 gallon jug of the yeast, sugar, water CO2 dillywhoo into my cabinet last night, the plants are looking better already. My question is 1 gallon C02 enough for those baby plants,..pictures below. Should I also seperate those two plants that are in the same pot now? or leave them be, I'm afraid of shocking them. They are at their 5th/6th node, should I wait about another week and start 12/12, whats your suggestions. The picture with Rating: 5
