Thought I,d through my 2cents in here . ANY hot or organic type soil mix does require a cook time for "optimal results" Google up on organic soil mixes and you'll learn why . Now given that you'll notice I quoted optimal meaning you dont have to but it wont be all it can be . Cooking the soil ,and this doesnt nessesarly mean it has to be in the sun , means that elements in the soil are being broken down by myco and other micro life in the soil this process makes nutrient uptake more readily availible and at a broader ph spectrum . It simply something you have to do , google composting and you will also learn this process and the temps required and the heat it generates . Hint hint . PEace !
