Aussie growers help

Hey all I’m looking at doing a outdoor grow later on this year and wanted to know if anyone could recommend a soil I could buy from maybe Bunnings I’m in WA and that’s pre much the only place in town I can think of to get soil potting mix I do know that a lot of it is crap tho so any recommendations??

Hey there I’ve been doing the same thing here in wa As for soil i started with pretty much sand first I went and got 70 kg bags of manure in wangarra the area is about 30 square mtrs I started with 5 bags sheep 5 cow 5 horse (unlined) and 2 chickeni mix Ed that in with a trailer load of soil improver I got from Malaga soil ant soils (it’s like a black mulch (with no sand added) mix in garden well and do it now and by sep you will be in with a chance. My first post. Sory if a bit long cheers
