• If growing organic is ph up or down good for your plants ? What about using vinegar for getting the ph down ?

      • I think for organic ph isn’t very important. I would hold on for another reply if you want real advice.

        • I grow organic and use extremely hard tap water so it comes out around 8.5 pH. I use PH down (mine is basically just citric acid) to bring it into the 6s and after that I don’t care. The soil will buffer the pH for you so you just want it in that 6ish range. If you’re using RO you shouldn’t need to pH your water.

          pH becomes much more of an important factor when growing in neutral mediums like coco or soilless medias like RDWC.

          • Well I have high ph same as you mines 8.1 with a charcoal filter or not I did a test with just my water diluted some apple cider vinegar and it stright dropped it to around 5.4 I guess I added a bit to much too the fist mix but when I plan on giving them water I’ll drop it slowly to 6.5 or so I think the recharge and few other things are working out but I haven’t tried my run off yet

            • @LysergicFox 6.5 should work perfectly fine. And once you measure out the vinegar once it should be easy to assume the pH each batch you make unless you’re adding other things to the water.

              Also if you’re growing organically and in soil I wouldn’t recommend watering until runoff. You will be washing nutrients out of the soil and you aren’t replenishing them the same way as if you were using coco and watering with actual feed.

              • @LysergicFox do you get a meneral build up in your pots?

              • Recharge can help with pH for most people but I too have tap water coming out at a pH north of 8 and I absolutely have to correct it into the 6 range. I grow organic but am flexible on however the pH is brought down, so I guess technically I’m not fully organic, don’t tell anyone lol. I’ve used General Hydroponics and Fox Farms pH down products.
