The mushrooms are grown from waste coffee grounds - they have no smell or taste of coffee, its just an excellent use of an otherwise waste material to grow mushrooms with. I got this mushroom growing kit from a community interest company called "Fungi Futures" - their kits seem to work an absolutely treat, check them out here: www.fungi-futures.co.uk/
This is what I filmed it with: tinyurl.com/WingscapesTimeLaps...
Unfortunately I had to go on holidays for 4 days (had to go on holidays, lol) and missed the perfect harvest time. So instead I decided to experiement with watering, and letting them dry out, for almost a lifecycle style time lapse movie of mushrooms growing, and withering.
I have another fungi futures growing kit, so I will try this again shortly. I will also show you how/what I did in "The Loft Garden" series
