  1. Hey guys, I'm thinking of growing this spring and I have no money to buy soil, but i have a TON of well composted horse shit and I was wondering if a mix of about 75% worm castings and 25% horse compost would be good soil? I'm growing Northern Lights if it makes and difference. Thanks:smoke:
  2. horse = N mainly
    castings = N mainly

    you need
    P: bat guano, bird guano, bone meal ...
    K:kelp, ashes, green ferts ...

    OR chicken shit complete in NPK

    Also slow release organic ferts are good imo (cheap and complete)
  3. Corto you like slow release? I always thought they were kinda risky...
