Erde des letzten Anbaus wiederverwenden?

Anything is possible my friend remember there are people out there growing weed plants in rockwool so I’m sure any type of compost soil you have will work Now you need to keep in mind you don’t know how strong the compost is so maybe mix like 50% fresh compost and 50% soil from a store Personally thou I know soil is an important thing when growing weed and having a stable soil that starts at a nutraul ph helps growing a ton I would suggest just going and getting some cheep soil and mixing in some amendments Keep in mind we are different people and I want you todo you. If you have that compost and wanna save some money I totally get it I would say to test the ph of each pot of soil you make up and try and buff the substrate so it’s closer to 6.4 or so I can only imagine the oh is not near that at all
