Plastic Seedling Trays Product Parameters

✅ Thickness: The standard thickness is 1.0 mm, about 155 grams. More thicker or heavier means the trays will be stronger to increase their life span. Our nursery trays thickness range is 0.8 mm-1.5 mm thickness.

✅ Depth: Our plastic seed trays standard cell depth is 3.7cm - 6cm. We also have deep root seed starting trays for fruit trees and young plants which need deep depth. The height of these trays is 6.5cm to 13cm.

In an appropriate range, the deeper the seed starter trays is, the greater the amount of oxygen it enters. This is more conducive to the extension of plant roots and the absorption of water. So the root growth is better.

✅ Hole Shape: The holes are mainly divided into square holes and circular holes. For the same specification of the plastic seed trays, square holes generally contain about 30% more growing medium than round holes. The water distribution is more uniform. The root system of the seedlings is more sufficient.
