The soil is continuously re-used by mixing with processed kitchen waste, and yields average around 1/2 lb per ft² for leafy greens - much more for things like tomatoes or peppers. Opex is around $600 per year inclusive of the device used to process kitchen waste, all beneficial/preventative microbes, additional soil and propogation supplies - plus the occasional bottle of cal-mag when things get wonky.
Lighting is automated and watering + propogating is 30 minute, twice per-week task. From time to time I employ various passive hydroponic mechanisms for faster growth and/or vacation watering + feeding, with a record of nearly 3 months for larger plants in the tent including carrots, tomatoes, and brussel sprouts.
Below are some photo posts of various configurations, components, and results/plants grown. Please direct any questions or comments here!
