I also thought this was a very cool bit of circular repurposing - the herb roots grow in a mat within the #hydroponic tube, which they peel out to clean the tubes when the crops have finished. They dry them off and then use them to grow #microgreens on, then eventually the whole thing gets composted.

I got to have another look around the #UniversityofExeter's #hydroponic greenhouse today - these are the herb plants (basil, coriander and parsley mostly). They focus on high value crops for fancy graduation dinners and the like, like herbs, edible flowers, salads and heritage tomatoes because it wouldn't be cost efficient (in terms of staff time rather than materials) to do bulk crops like potatoes.

I got a chance to have a nosy round the #UniversityofExeter's #hydroponic greenhouse yesterday, that grows some food served on campus. Very cool!
