Ive been spending around $5k on fox farm soil every summer and just leave the soil in the pots until next summer when i dump it out. I'm thinking about reusing the fully flushed soil and supplementing the lack of nutrients in the soil with chemical fertilizers and micro nutrients during watering. If hydroponics requires only a nutrient water mix, i dont see why using chemical nutes wouldnt work for soil that isnt fully charged. Seems like a lot of people are going fully organic but the soil recipes would cost me easily $10k. What are your thoughts on this?
