Hi everyone,
I'm considering building a walipini, but the small width of the land I can use raises some concerns.
Is a 4x3 m (13x10 feet) pit big enough to benefit from the warmth of the earth? I take the 2m (~6 feet) depth as some kind of standard.
The two main uses of the walipini would be:
1) the northern wall or the northern side (sunlit area) would serve as seedling growing area,
2) the southern side with a lower ground (darker area) would serve as a rain water reservoir.
Inviting your opinions here: would this be something reasonable or simply too small to work?
