HDI Root Riot Tray | 50 Peat Starter Cubes with 50-Cell Insert and Tray

HDI Root Riot Tray, Ready for Cuttings Out of the Box

The kit pairs 50 Root Riot cubes with a 50-cell insert and a solid black propagation tray. The outer tray has no drainage holes, so it catches runoff on a shelf or bench. Printed instructions come in the box, and the assembled kit measures about 21.0 x 10.7 x 2.6 in. Each cube is a 36 mm block of naturally composted, fine-milled sphagnum peat with a planting hole formed in the top. That spongy peat holds water and air together, which is what a stem needs while it calluses and pushes roots. The cubes arrive pre-moistened and pH balanced at 6.0, so the tray is ready the day it is opened. Take softwood tips, cut diagonally below a node and strip each one to a couple of leaves. Dip the cut end in a rooting gel, then set it into the hole just far enough to stand. Forcing it deeper crushes the sponge that holds the air. Mist, cover with a clear dome and mist again every other day to hold humidity.

A Complete Propagation Kit for Seeds and Cuttings

Seeds use the same hole, then the tray goes somewhere warm until they sprout. Check moisture by squeezing a cube, and water should just reach the surface. Because the outer tray holds water, pour off anything standing after each watering. Cubes sitting in a puddle lose the air that makes them work. Warm rooms and heat mats dry the tray faster, so look more often when the bench runs warm. Once roots show through the sides, each cube lifts out of its cell and transplants whole into soil, coco or a hydroponic system. Root Riot stays stable in recirculating setups and will not clog filters. The insert and tray carry on after the first run, and Root Riot refill cubes slot back into the same cells. The cubes are safe for use in food production environments, so vegetable and herb starts work in the same tray. The kit also carries Kosher certification.
