Comment: It's not, at the moment...

We are building a new dome for our final, permanent system and renting a tiny trailer in the meantime. The dome is done, now we are working on a rocket mass heater. Then we will set the system back up.
The last time I checked, there was still celery growing in a pot that I just tossed into a shed last fall when I broke the system down, so I guess it might still be growing celery... lol!
