Flexi Tank Pro

How the FlexiTank Pro Works

FlexiTanks have been around for years now, and have earned the trust of an army of growers. It took a while to get people to ditch their solid tanks, but once you try a FlexiTank, there’s no going back. They get the job done exactly as they’re supposed to, but they’re much more convenient to move around than regular tanks. The Pro version has been designed after factoring in years of customer feedback and is easily the best quality collapsible tank on the market – nothing else comes close.

The white reflective skin on the FlexiTank Pro helps to prevent nutrient temperatures from increasing, which is a particular issue in the summer months. When temps creep above 21 degrees celcius, nutrient solution loses its ability to hold on to dissolved oxygen. With reduced oxygen levels, plants are particularly vulnerable to root diseases, like pythium. Switching to a FlexiTank Pro is one of the things that you can do to help avoid the problem in the first place.

It comes with a tap on the front and three inlet / outlet points with grommets for your pipework, making it incredibly versatile. You can fit standard 13mm (internal diameter) IWS pipework straight through, making this tank compatible with pretty much any type of grow system, whether it’s an Autopot, a Flood & Drain or an R-DWC. If you want to use larger pipework, you can do this by screwing on an adapter. If you don’t need these grommets at all, just use the supplied blanking caps to seal them off instead.

Inside the lining are fill-lines marked in 10 gallon and 25 litre increments. Use these fill-lines to establish the volume of nutrient solution in your tank. This will, in turn, allow you to administer nutrients at the correct concentrations.
