This coco coir fiber grow mat outperformed the hemp TerraFibre grow mat and bamboo grow mats in our tests. The thickness and airy structure allowed for excellent root development.
We recommend soaking coco coir grow mats for a few hours before planting. Although we didn’t in our testing, we feel that having the coir soak up more water will give seeds a better chance of growing. Especially around the edges of the grow mat.
The mats are 9-1/2 by 11-1/2 inches and 1/2-inch thick.
The coco coir fiber grow mats will fit inside a 1020 tray (see images) but not the entire length. Use a pair of scissors to cut the mat to size. The fibers are tough but manageable with scissors.
