I'm no expert but I usually keep mine in a solo cup under my small lights for at least 2 to 3 weeks and then transfer to 3 gall pots under the big lights for at least 5 weeks and then flower for 9, 10, 11 weeks or whatever you feel. Anyway you can get a ton of different advice on here, some being right some being wrong but it is strictly opinion only, but like I said this is just my way that doesn't make it right or wrong.
