  1. i was wondering because i am having great success with growing my plants outsde in pots and i wanted to know if i could just keep the potting soil all winter and just recycle and use it for another grow next season
  2. Using old soil can lead to more trouble than it's worth. The fertilizers add salt to the soil even with costant leaching the soil will eventually become toxic to the plants. Just buy the same soil mix again(use new soil). To reuse soil it involves washing and steaming or cooking it to kill and bacteria, I thought about the reuse factor and I don't think it's worth the hassles. Reusing soil is usually done in massive greenhouse operations (cannabis or legal plants) it's the cheap way out and cutting corners doesn't always lead to the best results.
