Grow1 Round Grow Lids - 6.5-in - 40 Count

Dual-Sided Light Control for Containers - 40 Lids

Open growing surfaces let light reach places it should not, and that invites algae and mildew. These round lids give you two faces: black to block light and white to reflect it, so you pick the side that fits your setup. The black face blocks light, and the material is a 5.5 mil film.

This unit holds 40 round lids at 6.5 in, so it fits growers covering many small containers or sites, from a regular indoor grower to a small commercial room. A single unit is enough to cover a full tray of small sites without reordering.
