The individual cells measure 1.625" wide x 1.75" long x 2.75" deep—providing ample room for young root systems while maintaining compact growing dimensions for high-efficiency setups.

I use these every year to start my garden, can't beat the price.
I like these. They're deeper than the average 6-packs. I always have problems with the roots circling around the bottom of the shorter ones before it's safe to put them into the garden. These give some room to grow without having to do an intermediate transplant.
I'm growing my spring veggies, like cabbage, broccoli, lettuce etc to transplant with these containers, and so far really like them! Really good price too.
These trays are awesome. Great price and great product
Good amount and quality.
