I have a friend who teaches science to junior high students in Hawaii. Years ago he won a grant for a hydroponics and aquaponics garden, on which he has spent many weekends and afternoons.
If you don’t know, hydroponics is the art of growing plants without conventional soil. Instead they take root in an inert medium that you feed with all the nutrients they need. Aquaponics goes more wild still, with the nutrients coming from a colony of fish that the gardener feeds. And they’re after him to try aeroponics (growing in just mist) too. They kids blog about it and he asked me to share. I can’t say no to that.
I plan to run my own hydroponic bucket (Tomatoes for my mother, Gentle Reader.) when we have a but more sunlight in the frozen north.
