The Proptek 21.1" x 10.6" are designed to produce consistent, exceptional quality plants by developing quality natural root structures. Due to the injection moulded construction, Proptek trays often have more cells and produce more plants in the same amount of space than traditional Styrofoam or thermoformed trays. The trays come in various sizes and cell volumes to fulfill your own individual growing needs.
The injection molded construction also lends itself to other features, such as root training ribs and larger cell drainage hole. This means roots are better quality, circle less and can't embed themselves into the cell wall which all means a much easier plant to pull. So easy in fact, that you can often pull a little earlier and damage the plant less than if it was at the usual time in a thermoformed or Styrofoam tray.
The heavy duty design remains lightweight, but has a long extended working life usually up to 10 years with multiple cycles per year.
Not designed for use with our Heavy Duty, Extra Heavy Duty or Mega Heavy Duty 1020 Trays.

this is a very sturdy planter, 72 holes; heavier duty than typical of yours, far far better than jiffy
Very sturdy, self-supporting trays that drain well. They will last me for years.
Very sturdy, high quality tray
While the construction of these trays is substantial, they are too big to fit in the heavy duty trays. I expected that they would fit and didn’t check, so it’s my fault, but it limits their usefulness in starting seeds. I had to take a saw to them and cut a row off of each side
