I have worked on a few experiments; one with growing hydroponics, one with permaculture and one with oil algae.
At the moment they all look as if they have worked and will continue to work well. I've managed to grow some lettuce in the hydroponics and plant the pernamculture plants and I have some algae growing in my photo bio-reactors.
For the hydroponics, next year I want to start looking at producing my own nutrients. For the permaculture I need to see if the plants last the winter. I don't know of anyone who has tried permaculture this far north (63 deg). For the algae I now need to see if I can harvest them and produce some oil.
