Grow Pots

Quick question....if I have my 10 week old GG#4 in 7 gallon fabric pot roots are starting to come up through the soil should I go with 10 gallon or 15 gallon to put in through harvest ?

Indoor? outdoor? Roots on top of soil or out the bottom?

Roots out the top are fine. They'll either grow bark, or they'll air prune.
Both are ok.

My plants always have a ton of roots on the top of the soil; exposed.
Mine are older than yours, and in 2gal fabric pots.
