Thank you, I'll have to do some research for my next tank!Hi all,
I don't know where you live in Sweden, but you may be able to <"pick your own soil"> particularly if you live near any drumlins <"https://faculty.washington.edu/tswanson/302add/ESS Readings/drumlins_sweden.pdf"> or terminal moraine?
I'll add in @Tyko_N, they may have some suggestions?
I know you don't have a lot of soil in many places, due to a combination of some <"very old rocks">, a cold climate and <"glacial scraping">.
cheers Darrel
