Sorry, I forgot to answer the OPs question
Look up Air Pots. They work great , and will last for many grows (sorry no picks in action). I stuffed mine with lots of polished rock/stones and used a Hydro Halo drip rings over a one gallon pot
Here's the stones in a F & D tote, but the principal and technique are the same in Air Pots
I start in 3" net pots (see pic). When ready I transfer them into a one gallon net pot lid which fits perfectly. I then side fill with more stones and lower onto the one gallon AP. add the Hydro Halo drip ring and let er rip
Im going to go back to it next grow at least in one tent
