The 220µ canvas and waterproof backing seal ventilation ducts and cable holes hermetically. No more odour leaks or pressure loss inside your grow room.
With 28 N/25mm on steel and 105 N/25mm in tension, this tape holds firm under stress. Ideal to lock down flexible ducting, seal grow tent corners or fix exhaust outlets.
Engineered for the heat near your horticultural lamp. It keeps its grip close to hot extractor fans or in unheated rooms during winter cycles.
Yes — the opaque black colour and 220-micron thickness make it ideal to block light leaks (door joints, tent corners). Combine it with a flexible duct sleeve for optimal insulation around ventilation outlets.
Is one 5-metre roll enough for a full grow tent?For a standard 80×80 or 100×100 tent, a single 5m roll covers main seams and duct fixings. For larger grow rooms (≥120×120) or complex setups with multiple air outlets, plan on 2 rolls to be safe.
The essential accessory experienced growers always keep in their toolkit: discreet, ultra-resistant, built for the specific demands of indoor cultivation.
