Awesome Cells
I've been living off of recycled pots for years. These are just what I've been looking for. Decent size. Deep and I think I'll get several years out of these. I'll probably be buying more.

Good and solid
These should last years

Great Quality!
I love these inserts, very good quality and I know I'll have them for many seasons. Highly recommend.

4 cell plug trays
Love the larger, deeper size and how easy it is to pop out seedlings when ready.

Amazing!
Love these tray inserts. Very sturdy and easy to clean. The different colours help keep varieties of vegetables organized without the need for individual markers. Have them in all colours!

Love them!
Sooo nice to use! They don’t bend or twist when filling with soil. All the bottoms sit level on tray so all cells wick up water the same! Would highly recommend!
