Air Prune Propagation Tray - 72 Cell

What are the cell dimensions?

The cell dimensions are 1.37" square, are 2.29" tall, and taper to 1" square at the bottom. The drainage hole in the cell is .87".

Are these compatible with humidity domes?

Yes the dome will fit over the air prune inside a deep 1020 tray. The dome will not rest on the edge of the air prune tray.

These trays are very robust & providing good results. Filling them with seed starting mix is a bit messy though, because of the spaces in between the planting cells. Is there any simple way to block off those unused spaces during filling, to make the process more straightforward and less messy?

Will these fit into the extra strength 1020 tray? I prefer not to use the shallow trays if possible.

Yes they will! They will fit but just be aware that since they are the same depth as the tray they're nestling into, that removing them will be a bit more difficult. Placing a finger into the air holes at the top should make lifting them. out fairly easy.

I have a standard 1020 (72) cell vacuum seeder and automated dibbler setup . Could these existing tools be used with the air prune trays?

We recommend you measure the dimensions of our 72 air prune tray, including the cell size against your vacuum seeder. Because these trays are specifically designed to fit the dimension of our trays, it is difficult to say if they will fit another brand of trays or seeding equipment.

Will the air pruning tray fit into the s 1020 shallow microgreen trays?

Yes!

I have 2 questions: 1. Are these trays made from recycled plastic? 2. It seems that the hole at the bottom of each cell is rather large. How do you prevent the potting mix from just falling through and out the bottom?

Both the black and colored air prune trays are virgin plastic. A pre-moistened mix will help reduce the amount of matter that falls through the drainage hole.
