Probably the best seedling trays I've ever used. Really good quality, excellent drainage and air flow. It's build quality and size are perfect. We'll see what my seeds say in a few weeks. Good quality, thick and built to last

Why go through the hassle of cold-stratifying seeds, then germinating them, if you're going to transplant them into a pot where they're likely to become root-bound (this is when the roots reach the end of the soil, and hit the inner wall of the pot, so the roots start to branch out within the pot, going around in a circle, and eventually choking out the seedling, with its own roots).With air pruning cell trays, each cell tray has a slit that runs from the the top to the bottom. Once the seedlings roots branch out and approach the inner wall of the cell tray, because there's a slit in each tray, the roots are exposed to oxygen. The seedling will then stop putting energy into that particular roots' development, and create NEW roots in other areas.The end result? A seedling with much more EVENLY DISTRIBUTED roots, which equal a greater chance of survival. A total game changer.It's very sturdy & well cconstructed. This will be the last cell tray you ever buy.

These were a costly investment but such a high quality, I am sure they will be in use for years.Very happy with the full set-up of bottom tray, seed trays, and humidity domes.I’m also happy with how they stack, and I’ve tray can be used to tamp down the seed starter mix in another.

The tray is super sturdy and the side slits keep the roots growing evenly and eliminate water saturation. The bottom holes are a little too big, but I use a 2x2 inch paper towel at the bottom to keep soil in.

After years of ruining lettuce flats trying to get the plant plugs out, then ruining lettuce plugs trying to reuse the damaged flats, I needed a more durable solution. We start indoors in 20x10 flat trays, so I wanted something that would nest in these efficiently.These "72 Cell Air Prune Trays" are perfect! They're thick, so as long as they're not brittle they should hold up with years of use. They have large holes at the bottom to make transplanting easier. And maybe the air pruning slits will be helpful, but honestly I would have bought them even if they weren't air pruning.The trick with these looks to be filling them. The large holes at the bottom and the gaps between cells promise to dump a lot of potting soil without some sort of a plan to fill them. My current idea is to place one tray on a flat surface to cover the bottom holes, then pour soil over the surface (some spilling between the cells), and use a second tray to press gently and compact the soil. Then transfer the soil-filled tray to a 20x10. We'll see if this works next spring!
