Food growing and there is some compost at the Abbey Road Hive (84 nabbey rd nw8, next to rowley way / ainsworth estate) which I think we can get some of.
they also have some top soil i think and are growing lots of veg there.
the gates seem to be open all the time (to get compost) but i think someone is there tuesdays 2-5. not sure if this is for residents of the estate or camden or just anyone.
