Flexi Tanks and Reservoirs

Tanks are essential in all hydroponic systems as hydroponic techniques require constant nutrient solution passing over the roots - even automatic irrigation systems for soil or coco require reservoirs for daily feedings. Recirculating systems can operate with a smaller reservoir for a longer period of time than run to waste systems since recirculating systems continuously run the same water around the system while run to waste nutrient solution only passes through the system once.

Tanks and reservoirs are often overlooked by newcomers who tend to purchase setups that require hand watering or have an inbuilt tank. It will make your gardening experience much easier to purchase a tank since you’ll be able to leave your system unattended for much longer periods of time, safe in the knowledge your plants will remain hydrated.

We stock a range of different types and sizes of tank so whatever available space you have there will be the perfect tank and reservoir for plants requirements and systems size.

Hard Solid Tanks

Solid tanks or water butts come in a range of sizes but are only available in store due to their bulky nature. Solid tanks are extremely puncture resistant. Solid tanks can be upright so they save you space or they can be low-lying, so when full the weight they carry will be spread out over a larger area.

Soft Flexible Tanks

Our Flexi-Tanks are available in a range of sizes and are shipped flat-packed so are easily collapsible for easier delivery, transport and storage when not in use. Flexi-tanks have capacity markings so you won't have to mix a whole tank of nutrients if only a fraction of a tank is required - you’ll also be able to get an idea of how much nutrient solution you’re using.

We recommend using an air stone in your reservoirs and tanks to keep air bubbling through your nutrient solution while it’s sitting - this will keep it oxygenated so the nutrients will remain in their most available form for perfect plant performance. The dissolved oxygen will facilitate the plants uptake at the root so keeping your solution oxygenated will allow the plant to process more water and nutrients.

All of our tanks, reservoirs and water butts are strong and robust so can survive the most clumsy garden environment.

Top tip:If you mount your humidifier high up in the room and run the output to your tank, the moisture removed from the air will top-up your tank and allow you to leave your plants for even longer before manually changing the tank. Be careful that the dehumidifier doesn’t overflow your reservoir by never filling it to the brim.
