Hydroponics

Chris Wimmer of Captain Hydroponics recently dropped me an email to say hi. Having recently visited the Biospheric Foundation in Salford and seen their experimental urban aquaponics setup, I was interested and asked him a little more about hydroponics.

Chris says:
“Hydroponics is the practice of gardening without soil. This method allows you to grow your plants with less water and fertilizer than traditional gardening. You can even get creative by reusing existing household items in your hydroponic systems.”

His site explains it all in more detail. I quite like the look of this simple DIY system. I already have an airstone (bought for making compost tea) and I’m sure we have a plastic box kicking around somewhere. The 2-litre plastic bottle idea doesn’t even need an airstone, and this hydroponic microgreens setup is even easier. (Chris tells me that you can use non-peat alternatives to peat moss.) I shall see if I can give one of them a go this season — or if anyone reading does, please report back.

In case you’re wondering: the difference between aquaponics and hydroponics is that aquaponics also involve fish, with the idea being that the fish waste products act as fertiliser for the plants, with the plants therefore keeping the water clean. The Biospheric Foundation setup also involves compost, which in its turn produces worms to feed the fish. Graham Burnett at Spiralseed wrote up the LAND trip to Manchester that I was on which included that visit.
