I originally was going to use 18oz solo cups. Then I wondered if the seedlings might put out too many roots after 10 weeks for that cup to hold. Now that I'm thinking the seedlings will stay in these pots for 12+ weeks I'm really concerned that they'll need the leg room.
Just checked and I can fit 48 1-gal pots in my racks-- perfect for my situation.
Plan on bottom-watering which may help with the gnats, and I see various Gnatrol products on amazon that I'll consider too...
