4 cell plug tray inserts
Excellent product, my fave so far. The air pruning feature is the best, seedlings are very healthy. The inserts are nice and strong and have come through very well after a few years of use.

Great design
These work great with those plants that have large deep roots. I started some asparagus in these and a different style, shorter cell tray. The roots and overall plant condition was way better coming from these trays than the other ones.
