GT901 - Correx Top Plate - Genuine Replacement for Your Gro-Tank
Best for: GT901 Gro-Tank NFT system owners needing a replacement top plate for their larger 80-litre system.
Our thoughts
The GT901 is a big system running six to twelve plants, so its top plate takes a lot more wear than a small tent setup's would. Worth having a spare in mind before the original gives out mid-cycle, especially given colour supply can vary between silver and black.
This is a correx (corrugated plastic) top plate sized for the GT901 Gro-Tank NFT system, an entry-level nutrient film technique kit built to run around six to twelve plants under roughly two 600W lights. The plate covers the growing channel to block light from the nutrient solution and root zone, reducing algae growth and helping keep the system running cleaner for longer between cleans.
It's supplied in silver or black depending on current stock. Colour makes no difference to how the plate performs, it's purely cosmetic.
How it compares
As with the smaller GT205 plate, there's no real cross-brand alternative, just correctly-sized replacement parts.
- Vs a generic correx sheet cut to size: this plate is sized specifically to the GT901's longer tray and channel footprint, rather than needing trimming to fit
- Vs leaving a damaged plate in place: a fresh plate restores proper light-blocking across a system this size, where algae in the channel affects more plants at once
- Vs replacing the whole GT901 tank and tray: a fraction of the cost of a new complete system for what's usually just wear on the plate
It's a straightforward like-for-like spare rather than an upgrade, sized correctly so you're not adapting a generic sheet to fit.
Usage guidance
Fitting
Lay the plate along the full GT901 channel length so it sits flush with the tank at both ends.
Cutting holes
Cut net pot or rockwool cube holes to size before first use if the plate isn't pre-cut to match your existing spacing.
Colour
Silver and black plates function identically, so treat colour as cosmetic only when ordering.
Technical specifications

- Material: correx (corrugated plastic)
- Colour: silver or black, depending on stock
- Function: light-blocking cover for growing channel and nutrient solution

Who this is for
- GT901 owners whose original top plate has cracked or degraded
- Growers running the larger 6-12 plant GT901 system who want a spare on hand
- Anyone not fussed about matching plate colour to the rest of the kit
Our take
On a system running this many plants, a light-tight top plate is doing real work keeping algae out of the nutrient channel, so it's worth replacing promptly rather than running on a damaged one.
Silver or black, it does the same job either way. Does exactly what it should, day in, day out.
