Net Pots....Does Size Matter?

New guy here with Hydroponic's. I've been researching if there is a reason for the diffent size net pots, or why would I use one over the other with no real answers.
Right now I have some seedlings growing in an Aerogardern system that I'd like to move to some sort of larger hydro system. Will I have an issue using the small 1.5" pot of the Aerogarden system for any reason?
Thanks, Dan

Hi Dan, welcome to the Forum!

I have limited hydroponic experience but I do believe size matters. Those 1.5" Aerogarden pots could never put out roots like a full size basket, IMO....

I have grown 4 foot + plants that I started in 1.5" net pots, and then transferred those plants (still in the 1.5" pots) to a larger DWC system (6 or 8" net pot lids on 5 gallon buckets).  They grew great, no problems.  As long as the trunk diameter remains smaller than the top diameter of the smaller cup (all mine did), there should be no problem.  The roots filled my DWC buckets nicely, and the plants produced very well, despite going through the two net pots.
 
My only concern is if I were to overwinter a plant (I do outdoor hydro), the truck might eventually get too large for the smaller pot.  In that case, I'd just cut through the top ring of the smaller net pot.  Not sure if the main roots coming out of the small pot would eventually get strangled, though.
 
If in doubt, you can always move the seedling to a larger net pot before the roots grow too far out of the smaller pot.  I would imagine it would be difficult to remove a plant from a net pot once significant root growth has occurred.

Oops, just checked an mine are 2 inch.  And they have fairly large openings.  They are not Aerogarden pots.  I had hydroton balls in mine and removed them as the trunk grew larger.  Here's a pic:
