I ran some air through it today, and the bubbles are still pretty big, so i might seal up those holes and drill a hole for a 2" air stone underneath each pot. I bought 6 air stones today so I will probably do that, and ill leave the holes in the very middle that won't directly hit the roots.

.....I went a little overboard on the air pump and got this 1,000 GPH pump...
