New Grower Please help me choose an Airpot

[teaparty]

Rather a microgrower, I'd like to try an Airpot grow since I've heard so many good things.

I don't know what size to get, and if the "gallon / foot of growth" rule of thumb still applies for Airpots.

I use a 2.3 ft high mini tent, available space from bottom to bulb (CFL of course) being around 2ft. I LST every grow.
Would a 3 gal Airpot grow a too tall plant for my space? I've seen monsters grown in 2 liter airpots ,so there certainly is a difference.

I have found this link with all Airpots specs, not sure which size to choose.

I'd say go with the 2 gallon, same height as the 1 gallon. Every inch will count!

Get the 2 gal. equiv and put the bottom disc on the last available row as opposed
to two rows up as directed.
