Thank you for the reply.

I have been thinking of mixing my own soil, but would rather buy a pre-mixed bag and add perlite if it doesn't have it in there already. I Have a new bag of "Supergro soil" in my shed and says its 6.5-7ph in the soil with gurantees that there is no weed seeds or pests, will this be okay to use? More suggestions would be great. Thanks again Natural.
