Single Header Tank - Auto Top up system

Highly recommended!

Uses a header tank and float valve to automatically maintain the nutrient solution level in NFT systems. Allows you to leave your hydro systems for longer periods of time and provides an emergency water supply.

These are fantastic. They automatically top-up reservoirs on NFT systems from a 'header tank'. They work under gravity so no pumps or power required. These are great for weekends away, holiday time and unattended grow rooms and greenhouses as you can go away safe in the knowledge that your plants won't be going thirsty

Comes with 8 gallon tank, lid, float valve and all required fittings.
