Water Tanks
A greenhouse water tank keeps irrigation and nutrient water ready in bulk, so you mix less often and pumps never run dry. Pick a Grow1 collapsible tank for flexible or seasonal storage, a Botanicare reservoir for plumbed nutrient mixing, and the Peabody cone tank for full drainage.

Water Tanks
Greenhouse Water Tanks: Collapsible, Rigid and Cone Bottom
A greenhouse water tank holds irrigation or nutrient water close to where you grow, so you can mix in bulk and feed pumps on demand. The range covers 13 to 265 gallon Grow1 collapsible tanks and Botanicare 40, 70 and 115 gallon reservoirs. It also includes a 55 gallon drum and a Peabody 300 gallon cone tank....
Low-profile nutrient tubs for a single room live in our hydroponic reservoirs. Clean the source water first with our water filters and RO systems, part of the wider Air + Water + CO2 range.
Types of Water Tanks
Collapsible Tanks
Grow1 tanks are heavy-duty PVC that folds flat for cleaning and moving. Each has a removable straining screen, a 3/4 inch tap and valve, and a 3/4 inch fill fitting. Seven sizes run from 13 to 265 gallons. The 105 gallon tank stands 44 inches tall on a 29 inch base.
Rigid Reservoirs and Drums
Botanicare reservoirs are white ABS with front and side bulkhead ports for an external pump. The 115 gallon model measures 83 x 35 inches, and lids sell separately. The black HDPE 55 gallon drum holds 57 gallons actual and fits standard drum pumps and heaters.
Cone Bottom Tanks
The Peabody ProChem 300 gallon tank has a 22.5° cone that drains completely and helps mixing. It is NSF/ANSI/CAN 61 certified and sits on a metal stand sold separately.
How Growers Use Water Tanks
Store source water in one tank and mix nutrients in another, so clean water is always on hand. A Botanicare 115 holds enough that most rooms mix once a week instead of twice. Keep every tank covered, and close lid openings with a porthole cover.
Frequently Asked Questions
What color water tank is best?
Black or opaque tanks block light, which keeps algae from growing in the water. White tanks reflect heat, so they run cooler in a warm greenhouse, but they let some light through. A tight lid fixes that. The black 55 gallon drum and white Botanicare reservoirs cover both choices.
How do you keep algae out of a water tank?
Shut out light. Algae needs light to grow, so use an opaque tank or a white one with a fitted lid. Close the access hole with a porthole cover like the Active Aqua, which sits inside the lid. Covering the tank also slows evaporation.
What are portable water tanks used for?
Growers use them to store water where no fixed tank fits, or to move water between rooms and greenhouses. Grow1 collapsible tanks fold flat when empty and drain through a 3/4 inch tap. That makes them a good fit for seasonal setups.
