I'd like to add here that container size depends on veg and flowering times also... whether they are indica, sativa, or hybrid. Of course, we don't know that since it's bagseed, so I would be prepared for the 5gal's space wise. Also being from seed, they will need a little more root space than with clones.

Still go ahead and buy the quart and 3gal... maybe even one in between... then get the 5 gal's if you need them.

Personally, I start seeds in yogurt cups, then to a quart pot, then 10 liter, then 15 liter. 4-5 weeks of veg and 9 weeks of flowering. 3.5 square ft. scrog with 400w hps produced about a QP dry from 2 plants. :stoned:

Good luck:jointsmile:
