Who This Is For
- You are switching to a framed tank because your soft-sided reservoirs bulge and leak when filled to capacity.
- You are moving your reservoir outdoors because you need a UV-resistant body that won't degrade in direct sunlight.
- You are adding a heat-reflective lid because high nutrient temperatures are causing root issues in your grow space.
What We Found
- The aluminum frame stays rigid even when full, so you avoid that common bowing at the corners of the tank.
- The heavy-duty velcro on the Mylar lid is strong and keeps light out better than most loose-fitting covers.
- The 16mm barbed tap is low enough that you get a full drain without needing to tilt the entire tank.
What Users Say
- Growers who switched from plastic tubs say they stopped worrying about leaks after seeing the reinforced membrane.
- Users running large-scale setups say the Mylar lid helped them keep water temps stable without adding a chiller.
