These powder-coated steel slats are cleverly designed for making either humidity trays or bench tops for potting and staging benches. With large perforations (5mm), they provide excellent aeration and drainage. To make humidity trays, simply drop the slats into any water-retaining tray so that plants can sit above a layer of water to increase surrounding humidity without drowning the roots.
Available separately, our giant plant tray accommodates four slats; it is made of heavy UV-stable plastic and measures 25-1/2" × 17-1/2" × 3" deep.
Alternatively, preformed end holes allow you to quickly attach a series of slats to a wooden frame, making it easy to build a bench to your size and design preferences. As a substitute for wood slats, the steel slats provide a solid work surface that ensures good air circulation around plants and seedlings, and won't rot or mildew in damp conditions.
Sold in pairs; each slat is 22-1/2" × 3-1/2" × 3/4" high.
The Ventilating Slats are no longer available.
