Gro Pro Bucket Lid - Flat for 3.5 & 5 Gallon Buckets

The Gro Pro Bucket Lid - Flat is a flat, food-grade plastic lid designed for standard 3.5 and 5-gallon buckets, including Gro Pro black buckets. It is the piece that turns a common bucket into a hydroponic or aeroponic growing module: it supports the plant above and seals the reservoir below.

Benefits

• Compatible with standard 3.5 and 5 gal buckets, and with Gro Pro buckets.
• Food-grade plastic, suitable for contact with nutrient solution.
• Flat, stable surface for net pots, drip stakes, or cuttings.
• Blocks light over the reservoir and helps slow down algae formation.
• Can be custom-drilled to build DWC, RDWC, or drip systems to your liking.

How to use

Mark and drill holes for net pots or connections before placing plants, to avoid damaging roots later. Press the lid over the edge of the bucket until it fits firmly all around and check for any light-admitting openings. Between cycles, rinse and disinfect the lid, and replace it if it cracks or loses its seal.

Available at Pachamama Indoor Farming Culture, with shipping throughout Costa Rica.
