GT 901 WHITE TOP PLATE

Description

GT 901 WHITE TOP PLATE is the replacement and spare lid component for the Nutriculture GT 901 propagation and growing system, one of the most widely used NFT-style propagation units in UK hydroponics. We have been supplying Nutriculture system spares and accessories to UK growers since 2017 because keeping a healthy stock of key components means a failed or cracked part never has to stop a grow mid-cycle.

The Role of the Top Plate in the GT 901 System

The GT 901 top plate serves as both the growing surface and the light barrier for the reservoir below. Its white upper surface reflects light away from the nutrient solution, preventing algae growth that would otherwise colonise a warm, nutrient-rich reservoir exposed to grow room lighting. The plate’s pre-cut holes are precisely sized for standard propagation cubes, net pots, or rockwool blocks, holding them securely in position over the flowing or static nutrient film below. A cracked, discoloured, or missing top plate compromises both light exclusion and plant support — replacing it promptly maintains system hygiene and plant stability through the full growing cycle.

Fitting and Maintaining Your GT 901 Top Plate

The white top plate seats directly onto the GT 901 reservoir body with a friction fit — no tools or fixings required. Ensure the plate is fully seated around the perimeter so no gaps allow light into the reservoir. Clean the plate between cycles with a mild bleach solution or Oxy-Plus dilution to remove algae, mineral deposits, and organic residue that accumulate around the net pot holes. Inspect for cracks or warping at each clean — UV exposure from grow room lighting degrades white plastic over time, and a warped plate creates gaps that allow light penetration. Replacement is simple and inexpensive; keeping a spare plate means a damaged one causes no downtime.

Keep GT 901 White Top Plate alongside GT 901 Black Top Plate, replacement net pots, and Nutriculture system cleaning solution for a fully stocked spares kit that keeps your propagation system running without interruption.
