The 7" Dome Lid fits the 1020 Tray, and extends 7" above the top of the tray. This dome lid features a one top and two side vents which can be opened and closed.
The latest in seed starting! Styrofoam Floating Trays constantly wick via capillary action to keep seedlings perfectly hydrated. Fill Floating Trays with Gro-Plugs which are pre-shaped spongy plugs of stabilized rooting media that, made of coco fiber and small amount of a synthetic polymer, provide the optimum growing environment (note: Gro-Plugs may not be acceptable to all organic certifiers). Floating Trays can work with other potting mixes, but this requires experimentation to find a blend that will work. To put together your Standard Floating System, order a 1020 Tray, Floating 55-Cell Tray, Gro-Plugs, and either the 2" Lid or 7" Lid. Order all components separately.
