You can always grow in fox farms. I like coast of Maine Stonington blend tho. In the beginning it doesn't matter you can start in a solo cup etc add different soil in transplant. You can charge up soils with dry fertilizer. Buy yourself some Stonington blend fertilizer thru the mail if you got to and just top dress it will get in there. Some dry amendments break down faster that product does compared to say kelp. Look into knf. @Fermented_Fruitz ferments his leaves you can recycle all your stuff back in. Like sifted trim etc
