Description

Correx top plates for use in the range of Grotanks.

Correx top sheets are durable, lightweight, and waterproof sheets designed for use in Nutrient Film Technique (NFT) hydroponic systems. These corrugated plastic sheets provide essential coverage for NFT channels, protecting plants’ root zones from excess light exposure, which helps to reduce algae growth and maintain a cleaner system. Pre-cut to size for the Grotank range of NFT trays, Correx top sheets are reusable, resilient to moisture, and offer a simple, effective solution for enhancing hydroponic efficiency and plant health. Perfect for commercial growers and hobbyists alike, they help create a more controlled and productive growing environment.

How to use

The top plate sits over the tray and keeps light off the roots and the nutrient solution. Without it, algae grow in the tray and the system gets dirty.

Choose the size for your tank: GT205i, GT424, GT604 or GT100. Wipe it clean between crops and use it again. More NFT systems and parts.
