Ok so i have a few plants in those red plastic party cups. my plants are about 2 inches tall. how tall should i let them get before i should transplant? and im currently using MG soil they look to be doing a lot better so i stuck with it. but when i do the transplant should i still use the MG soil or should i switch to fox farm?
I'd let them grow til they are about 5-6" and then transplant them into the fox farm.. I like to let their roots get just a tad bit bound so the root ball doesn't fall apart when you transplant, and do it when the soil is dry, it holds together much better.
