hey tm, now that i look at my post it sounded kinda dick lol. (i question a bit much when im stoned.)

it sounds like u had some work cut out for you guys. it came out awesome if i could compare it to the vid and u guys built from scratch(no starting room)! no wonder it took 9 months

on the whole idea of potting.
1. smaller pots will be easier to maintain in a smaller area. (+saving on lights is a big plus for me whenever i can)
2. a oversized pot (in your case) with a small plant in it usually causes one to overwater. (water sits in most cases top gets dry u water but plant is actually Wicking water from the bottom) what happens... classic wilt. progressing to lean, or damping off/root rot.
3. smaller pots will help u learn weight technique. i use one hand to move pots around after a while u can tell when the water weights gone. with ten gallon pots u will be able to see a much bigger difference as well once u got it down.
4. all in all its saves money, teaches you about good technique to watering and event repotting skills. good basic gardening.

hope the rooms treating the clones well!
