Great Moisture Control for seedlings with Q-Plugs. Includes (1)- 55 cell foam insert (20 in. x 9 1/2 in. x 2 in.) loaded with Q-Plugs (each 1 3/8 in. across x 1 3/4 in. deep), (1)- 22 in. x 11 in. x 2 1/2 in. tan Perma-Nest tray and a clear plastic dome. This unique sponge-like growing media drains, yet retains moisture for complete control. Composed of organic materials held together in a pliable preformed plug, they’re great for seed starting and rooting cuttings, and the plugs will not fall apart upon removal from the trays. In fact, they’re so easy to handle, that we also offer bags of refills for easy insertion into the foam trays sold here. Q-Plugs may be either transplanted into pots for further plant growth, or placed directly into the outdoor soil.
