Root Riot Cubes, Bag of 100 | Peat Starter Plugs for Cuttings and Seeds

Root Riot Cubes by the Hundred for Bigger Clone Sessions

A bag of 100 cubes covers two full 50-cell inserts, which suits a grower taking cuttings from several mothers in one session. Every cube is a 36 mm block of naturally composted, fine-milled sphagnum peat with a planting hole formed in the top. The peat is worked into a spongy structure that holds air and water together around a fresh stem. Cubes ship already moist and pH balanced at 6.0, so a full batch can go in the day the bag is opened. Prep every cutting before the first one goes in. Cut each softwood tip diagonally below a node and trim it back to a couple of leaves. Dip the end in rooting gel and slide it into the hole only far enough to stand upright. Label each row by variety as you go, since young cuttings look alike for the first week. Mist, cover with a clear dome, and mist again every other day to hold humidity. For seed, set one in each hole and keep the tray warm until germination.

Root Riot Plugs That Keep a Large Batch Even

With a bag this size, consistency across the tray matters more than any single cube. The peat dries back evenly, so cubes at the edge of a tray stay close to the ones in the middle. Check by squeezing a cube from each corner, and moisture should just reach the surface. Water and drain well when it does not, and check more often in a warm room or on a heat mat. Reseal the bag after every session and store it somewhere cool and dark. Cubes left open will dry out, and a dried cube needs a lukewarm soak before it turns spongy again. Each cube holds its shape through rooting, so a full tray of young plants handles and transplants without crumbling. Once roots break through the sides, move the cube whole into soil, coco or a hydroponic system. It stays stable in recirculating setups and will not clog filters. They are also safe for use in food production environments, so vegetable and herb starts can share the same bench.
