These are the seedling trays I’m using this year.
1. I plant most of my seeds in 2″ x 3″ thin plastic pots, 24 per tray:
I’ve planted in plastic 6-packs for many years. I’ve made 100s of paper pots and I’ve used peat pots. But these are what I’ve come to like. I like them better than plastic 6-packs because I can plant fewer seeds of more varieties. Also it’s easier to give away one or two pots than to cut apart a 6-pack. They are thin plastic, but I can usually use them about 3 years before they rip apart. My only complaint: too bad they’re not compostable.
2. I’m trying plug cells this year for peppers, tomatoes, and eggplants. I’m using trays with square cells, 128 cells per tray. I’ll transplant the plants to deep single pots later, probably mid-April. I like to use 3.5″ square, 5″ deep pots for transplants:
