Hey yall, starting my first grow really soon and my partner is saying that after the seedling sprouts and its time to put in soil, to put directly in our 5 gallon pot. Is this the correct way to do it or should we start in a smaller pot and transplant later?
I would just start in the 5 gallon pot. Transplanting is not really needed. If your soil is good and properly watered your root zone will be healthy and strong regardless of how you start the plants.
I start in red dixie cups, leave them in there for about a week then transplant into their final pot. You can start in the 5gal pot though, it's really just personal preference.
I never bother with transplanting. I used to but really dont notice the difference. I germinate and straight to whatever size Airpot I use. I have yet to have a plant with a poor root system or anything.
