  1. hey guys

    I am hypatheticaly watering my seedlings with rain water i collect in my yard.

    I dont have a ph metre so i cant check ph. Will my ph be ok from rain water alone or shud i add lime i have here?

    Thanks ppl, Bionic

  2. I probably wouldn't add anything if there doesn't seem to be a problem.

    Then again, I probably wouldn't use rainwater in the first place... so I don't really know. :smoke:
  3. Don´t waste your money on a useless pH meter. Add lime to your compost, about an ounce a gallon.
  4. Cheers for the info man, a gr8 help :)

    Rain water is one of the best things to water your plants with durban, it has a ph of 5.5 to 6.0 so its good for the plants, hence y no1 checks their ph outdoors.

  5. AWWWWW shit i added a bit to much i added half more than i shud have
    so say i added 10 g i only needed 7.5. Wat shud i do guys? will too much calcium carbonate hurt my seedlings?
