I bought a 13.5 kg bag of grow wool. I purchased a 40 l plastic laundry tub. I then fill it with water and PH it down to 5.5. Then to leave the grow wool to soak and drain over 24 hours. I've repeated this roughly four or five times in that 24 hours hoping to flush the lime. Still hasn't stabilised. I now have it sitting in the bucket without water drying. I will then repeat process again. Any tips from experienced growers please.
