Elixir Gardens ® JIFFY 7 PELLETS - 41MM x 60 IN TRAY

A bit expensive but very good. Wish I could afford lots of them

They take a while to soak up the water and expand. I mean they worked but the amount of times I had to water was insane, it was everyday since it would dry out so quickly. It’s a good idea to save space but you can get smaller pots the same size it will be better. When my seedlings grew I opted to remove the mesh around the discs when I plant them in new pots as I heard it could kill the seedling despite saying roots will grow through it

If they advertise that it comes with a tray - then it should do so.
