Item Number: GP330
17" Square Seed Flat
Durable and Versatile Flat
Please note: These flats may have smaller holes in the middle section, but the flat still drains water.
Very popular for its versatility and durability, this seed flat holds the 6-pack sheets and can be used for almost any small containers or for soil blocks. The 1/4" mesh provides better drainage than perforated, solid-bottomed trays, but is tight enough to hold soil, if desired, for starting seedlings or root cuttings.

I love these trays and use them constantly! They are super sturdy and will definitely last a long time.
I am using these for growing microgreens and so far no complaints! I line the bottom with recycled brown bags and fill with compost. They're a great size and feel pretty sturdy.
Love these trays, especially for the price!
Now the trays organize my potatoes while they chit. Later they will support and arrange my soil block seed starts. And they also help organize small pots, garden supplies and utensils -- all the things that tend to "walk off somewhere" when you're not looking! Not too big and not too heavy. Just right.
My three inch pots fit in quite nicely and the perforations in the bottom keep the peet from getting soggy. Just what I needed.
