  1. Thanks for reading. I'm only growing 2 small auto flowering plants. Can I mix up say 2 gallons of water and set the oh level and than use this same batch of water all week? Once the ph is set, will it fluctuate over a week? Thanks.
  2. what kinda water are ya using...always ph before feeding plants..if its city tap you may need to use water conditioner like for aquaruims;)
  3. Ph will fluctuate. How much depends on a few factors. Hardness , D.O.(dissolved oxygen ), evaporation rate, dissolved solids ...
    R/O water will not fluctuate near as much as canal water. So to answer your question,you can make a large batch but you still must check your Ph .
