Ph for pro mix

Discussion in 'Growing Marijuana Indoors' started by JoshuaE, Aug 21, 2019.

  1. Pro mix guys what do you ph to?
    Do we still use the hydro scale since it is soiless ?
  2. LOL what difference does it make on what grow medium your using ????????

    PH 5.5 is the same regardless of grow medium its 5.5 …………………………….
    Everyone that checks and adjusts they're PH for growing MJ is still adjusting the PH exactly the same way .
    Some may use different products to do that but your still adjusting the PH ……………...

  5. Soil and hydro use two different scales . Its definitely not 5.5 as a universal number for all grow medium

  6. Whats different about adjusting the ph just because you are using pro mix ?
    There is no difference ….……………...5.5 ph in pro mix is the same as 5.5 ph in clay balls ….
    Just because the person is using pro mix there is no difference from adjusting the PH on anything else ..

  9. I didn't say 5.5 is the universal number for growing weed .
    I said 5.5 PH on a Pro mix medium is the same as a 5.5 ph in all grow mediums everywhere in the world .

  11. Ok nice point, I'm not sure how that applies to my question but I agree 5.5 is 5.5

  12. So what makes PH ing pro mix different from any other ph .
    IT Doesn't . ph on pro mix is the same as the ph in everything you check the PH levels on

    5.5 ph in cali using Pro mix is the same 5.5 PH in a soil grow in Japan. there is zero difference

  13. Everyone using pro mix needs to buy a special Pro mix PH meter ??
    I don't think so …………..……….

  15. I'm not talking about the meter or the method I'm asking the range I think the problem is you believe that there is only one ph scale for all medium I disagree.
    I'm happy to leave it at that. Screenshot_20190821-103816_Chrome.jpg
