Collection: Nutrient Tanks

Nutrient tanks

Nutrient tanks store and mix hydroponic nutrient solution for larger grow rooms and irrigation systems, and double as rainwater collection tanks. This range covers the AQUA-TANK foldable series — 50L, 100L, 225L and 400L — made from UV-resistant, BPA-free PVC and built for Australian conditions, with a tap, overflow valve and feed chart pocket on every size.

Why tank quality matters

Larger grow rooms and irrigation systems need somewhere to mix and store nutrient solution before it's pumped out to the plants, and a tank built for the job matters more than an improvised bucket or drum. AQUA-TANKs use heavy-duty 500D PVC that holds up to daily contact with nutrients, additives and Australian UV exposure, while their foldable design lets them fit into grow rooms and tight spaces that rigid tanks simply can't.

How to choose

Match tank size to your system's daily nutrient demand and available floor space. The 50L and 100L sizes suit smaller reservoirs, single grow tents or supplementing an existing system, while the 225L and 400L sizes are built for larger grow rooms or multi-plant setups where mixing and storing bigger volumes saves repeat trips.

If you're setting up your first hydroponic reservoir, the 50L or 100L AQUA-TANK is easy to fill, empty and store away between grows. Growers running a full room can step up to the 225L or 400L for less frequent top-ups, and every size folds down flat for compact storage when not in use.

All AQUA-TANKs are 100% Australian owned and designed for local conditions, held in stock at A-Grade Hydroponics. Not sure which size suits your system? Call or live chat with our Melbourne-based team, then browse the range below.
