Jump Start AccelaROOT 50-Cell Insert, 10x20 Tray & 50 Starter Plugs

AccelaROOT 50-Cell Tray: Tray, Insert and Plugs in One Kit

This is a complete propagation starter from Jump Start, the seed-starting line from Hydrofarm. It pairs a standard 10x20 tray, a 50-cell insert, and 50 AccelaROOT plugs already seated in the cells. Hydrofarm describes the plugs as a coir-based blend held together with a binding agent, pre-moistened and pH-balanced out of the package. That binding agent is what keeps each plug in one piece when you pull it for transplant. The plug texture carries small air pockets that encourage dense feeder roots, and the drainage keeps the stem base from sitting wet. That matters because damping off starts where water sits against the stem. Hydrofarm says no rooting hormone is needed, though cuttings can still take a gel dip if that is your routine. Assembled, the kit measures about 21 by 11 by 2 inches and weighs roughly 2.65 lbs. It fits standard 10x20 humidity domes and heat mats.

Keeping Starter Plugs Moist Without Drowning Them

Starter plugs like these do their best work when they stay evenly moist, never soaked. Because they arrive pre-moistened, most seeds and cuttings can go straight in without a pre-soak. Water from below by adding a shallow layer to the tray, let the plugs wick what they need, then pour off the excess. Cover the tray with a humidity dome for cuttings, since the kit does not include one. A heat mat under the tray speeds germination for most seeds. Once roots push out the bottom and sides, the plug moves as a unit. It drops into soil, coco or a hydro net pot without disturbing the root ball. That clean transfer is the real advantage over loose media. The insert and tray can be cleaned and reused, although the plugs themselves are single-use. Growers who already own trays can pick up the insert-and-plugs version without a tray instead.
