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

Each plant is growing our of its own aperture in an enclosed plastic tunnel supported on a wooden frame, and twining up strings to the glass roof

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.

Plastic tubes stacked like shelves on racks in the greenhouse, with an individual herb plant growing in evenly spaced cutouts in each. Curved pipes connect the tubes, clearly handmade because they're wrapped in Duck tape to maintain the shape. Behind the racks of shelving, not particularly clearly visible, is the reservoir tank and the pump that pumps nutrient-enriched water to the top tube from which it cascades down

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.

#Permaculture
A dry, dense fibrous root mat which you can see is the same width as the pipes, with a circular depression where the plant was removed.
