im sorry if i post a lot in maybe not the best places, im am still getting to know the forum.
we are using stone/rock a lot as season extender here. it isnt a greenhouse like structure, so maybe the wrong thread...
We ar in amsterdam, which is a temperate climate due to a mild sea breeze all year. so mild winters mild summers. but it can still freeze about -15 degrees Celcius, with snow and ice and stuff. the growing season is quite ok, but young sprouts sometimes die cos of late frost.
also we are in a city, and into urban PC. so we work with rock and discarded bricks buried in the soil. We have build a straw-berrie tower, i dont know why its called like that because all the ones ive seen got vegg and herbs in them but anyway.
it works a little bit like a herb spiral, but since its mostly stone surface it warms up early in the year, and we can keep harvesting from it a good 1,5 month longer than in our raised beds. almost everything gets bigger if it grows in the vegg. tower. tomatoes, kale, herb.
according to our pdc teachers the advantages are:
more soil volume than a raised bed that takes the same ground surface.
more growing surface than a raised bed on the same ground surface.
more different microclimates, sun, shade, half-half.
warms up due to the bricks.
at our website you can find some more about it, like fotos of building it:
