    Tasting before wasting

    My project for the past 8 weeks has been to look at how we could use waste streams from both the aquaponics greenhouse and the kitchen to feed our catfish to make the system as circular as possible.

    Nitrogen is a key component in chlorophyll, so it plays a crucial role inside the plant: but what happens when it's too much?

    Brand new easy to use PH & Temp meter

    To ensure the right living conditions for our fish we need to measure the PH daily. The liquid tests are quite a hassle and they're not always that accurate. So we bought an electronic one.
