pot size

so I have a question, what size should my pots be for indoor growin. I am thinking 3 to five gallons my dad got me some pots from a nursery and their like three gallons I think. like 12 in tall by 10 inch around at the top going down to maybe 8 around at the bottom

Determining your final pot size depends on how big you want each plant. For indoor plants I like to transplant as much as possible. If you start out with too big of a pot, the plants small root system can't get to the corners, and as a result, moisture may sit and stagnate, causing root rot. The unused soil spots will also become depleted of nutrition.
The best way to avoid this is to let the plant become root bound and constantly increase pot size little by little. Refreshing the soil AROUND the root ball, so that fresh roots can access fresh soil.
I find it best to start a seedling in a red solo cup. It will become root bound in a few weeks. Move up to a 1-3 gallon pot. Then I like to finish(flower) in a 5 gallon. Ive never used bigger than that for indoor grows. If I did, the plants would be extremely difficult to contain.

Hope this helps, best of luck to you.

It does help. Thanks buddy

Like Mr Big sez, small plant in a big pot chances over watering/slow absorption. I go from solo cup to 3 gallon bag or 5 gallon bag/pot. But I have to water carefully in the beginning.
