What Comes in a Root Riot Tray, and What Does Not

The manufacturer lists the contents precisely, and it is worth repeating because the product name has caused confusion for years. In the box: fifty ready-to-plant cubes, a fifty cell plastic insert, a black outer propagation tray with no drainage holes, and printed instructions. That is the whole kit. Rooting gel is not part of it. The product circulates under the name 'with Clonex Gel' at several retailers, but the manufacturer's own contents list includes no gel at all. Two distributors confirm the wording is only a recommendation to use one alongside it. If you want gel, it is a separate line. The kit measures 10.5 by 21 in and stands 2.75 in deep, which is the standard propagation footprint with lid clearance. Shipping weight is published as 2.3 lbs by one distributor and 3 lbs by another. The manufacturer part is RTRTTRY50 and the barcode on file, 659627011038, is confirmed against a distributor listing. One detail nobody else publishes: the product carries Kosher certification under KP.137.

How Plant Starter Cubes Are Made and How to Use Them

The cubes are naturally composted fine milled sphagnum peat moss, which is rather more specific than the phrase that usually circulates. The texture is the point of the product. A sponge holds air and water at the same time, which is what a new root needs and what a saturated medium cannot give it. They arrive pre-moistened and ready to plant. If they have dried out in storage, rewet them in lukewarm water until spongy rather than sodden, and keep unused cubes in their bag. For a cutting, take a softwood tip and cut diagonally below a node, then strip all but a couple of leaves. Dip the cut end in rooting gel and set it into the pre-formed hole. Do not force it into the hole. Push it in only far enough that it stands up on its own. Mist the cuttings, then cover the tray to hold humidity. For seed, drop the seed into the hole and keep the tray somewhere warm. Moisture should just appear at the surface when a cube is squeezed. When roots show through the sides, the cube transplants whole into any system.

Key Features

  • Fifty cubes, insert and tray: A complete kit, including a no-hole outer propagation tray.
  • Rooting gel is not included: The name says otherwise at some retailers, but the box has none.
  • Composted sphagnum peat moss: Fine milled, which is where the spongy texture comes from.
  • Pre-moistened and ready to plant: Rewet in lukewarm water if they have dried out in storage.
  • A pre-formed hole in each cube: Sized for a cutting or a seed, with no tool needed at all.
  • Transplants whole: When roots show at the sides, the cube goes into any system.
