Rapid Rooter Tray with 50 Plugs | General Hydroponics, 1.5 in

What Comes in the Rapid Rooter Tray Fifty plugs, in the tray. Part HGC714140 is the 50 cell insert supplied with the plugs seated in the cells, not a bare tray and not a bag of refills. Each plug is 1.5 in round, with a hole formed in the top. The material is sphagnum peat and composted tree bark, held together by a plant based foam binder. There is no soil in it. Working a 50 Cell Plug Tray From Soak to Transplant Soak first. Put the plugs in pH balanced water near pH 6.0 for about two hours. Squeeze them gently four or five times to push the air out. They are chemically neutral, so unlike rockwool there is no buffering step to plan around. Set a seed or a cutting into the hole and then leave them be; more seedlings die here from watering than from drought. Roots usually show in one to three weeks, about a week after the first true leaves open. A cutting is ready once roots come through the sides. The whole plug then goes into whatever is next, be it a larger pot, coco, soil or a hydroponic system.
