Okay, I’m using Fox Farms Ocean Forest soil exclusively for my grows. Can someone tell me how often to they use their potting soil for before trashing it out and buying a new batch? I’m trying to plan ahead for a fall and winter grow and right now, it looks like I’m going to be using 2 bags per two plants per grow. But if I can replant new seedlings in existing soil from my first grow at least once, it will cut down on expenses and having to store away bags of soil. And I’m sure there’s a shelf life on soil. I know that eventually plants will consume the nutrients in the soil unless I somehow replenish. Can anyone give me an idea on how to maximize my soil to it’s full potential before totally replacing the soil with a fresh batch?
