Does anyone else use apple cider vinegar to PH the water? Someone said not to use any vinegar bc it evaporates faster than water and gets back to neutral. I read online the opposite and it makes great ph Down. I also find my plants both in my tent and my windowautoflowerishealthy

Hey Growmie,
Apple Cider Vinegar is an organic acid that can be used to lower the PH of the water. It is important to note that your PH will be unstable in soil particularly, as the water evaporates it’ll make the water more alkaline again which could cause problems for nutrient absorption in your plant. Only use vinegar in an emergency situation or you’ll cause damage to your plants.

Check that water in 5-7 hours and ph will be off again.
Same happens in pot, soil gets all over, but not in needed ratio.
Ph +- cost pennies and last very long .
Its like 1 time in 5 years buy.

apple cider vinegar very diluted is used as rooting hormone for clones but not really advised to adjust pH.

Milorganite- has anyone tried it on cannabis?Has anyone ever used Milorganite on their grow? I have used it on my lawn many years and it turns the lawn a beautiful green. The best part about Milorganite is if you pour a lot on your lawn it does not burn your lawn at all. I know some people use it in their vegetable beds.Feeding. Chemical composition
