I've used several different soil mixes but happy frog was my first and favorite, only reason I stopped using it is because of gnat issues with it, but most other soils I've used come with bugs too so I'll get over it. My first complaint other than bugs about this soil is it doesn't seem aerated enough, though I'm no expert I've only done a couple harvests so i wouldn't really know. Aso Ive seen many people make there own fully ammended recipes with this soil using stuff like worm castings, Bone/blood meal, coco etc. I'm not looking to make a fully amended soil but I was wondering what everyone would recommend adding to this soil to make it an all around better soil. I was gonna transplant my clones first into cups with lightly amended soil, then wait until I get some big roots and need to start feeding to transplant in a nicely amended soil probably 3-5 gallons that they will be flowered in, so I was wondering what everyone would recommend adding to either of these mixes.
