Apologies if a similar question has been answered already. Just looking for a few recommendations on pot size for an indoor AI (nirvana) grow. This will be my first non bag-seed grow and I'd like to give the roots plenty of room in case my thumb turns super green. The strain... if you're not familiar: Nirvana Aurora Indica feminized (5 seeds) What I have already: Shop 14"H x 18"W x 18"D Resin Pot at Lowes.com Edit: Just realized I have the smaller size: http://www.lowes.com/pd_126826-77374-57914.0_0__?storeId=10151&Ntt=57914&UserSearch=57914&productId=3079605&N=0&catalogId=10051&langId=-1 Hoping these pots are plenty but I really don't want to run out of room. Should I spring for the bigger size? I really appreciate any help. Gracias.
