im going to buy a base soil instead of using the crappy soil at my house. There some that i can buy that has 60% compost, 30% top soil, and 10% sand, and theres another where im guessing its just 100% top soild. im mixing in perlite/peat moss/bone and blood meal/ and i think a few others, so itl be 50% soil and 50% all that other shit. should i get the 60% compost soil or the regular soil?
