So today i went to the local hardware store and picked up some items, i want to mix my soil a few weeks before i plant outdoors because i heard your supposed to let it get weatherd or something. was hoping someone could clear that up with me, do i leave it outside and let rain hit the soil or what. These are the numerous products i purchased for my soil recipe. Organic Choice Blood meal (miracle grow), Organic Choice Bone meal (miracle grow), Vermiculite, Organic choice organic potting soil (miracle grow), Perlite, Lime, and some compost from a plant store. I was wondering how much of each of these i should mix with my pro mix soil. I was wondering if anyone had any soil recipes. I was planning on mixing it on a tarp or something and storing it in a big garbage can or something. Also, i have the advanced nutrients hydroponic organic nutrient lineup if any of that could be added to the soil or if it would be necessary to mix a nute mix to water later in the year. Thanks for anyones input, i just want to clear up these few things before i mix the batch. I was worried about the blood meal / bone meal and other essential nutrients depleating if i do leave it outside to get weatherd. so im commin to the big dogs for a little assistance =P haha.
