I am looking for someone that works or knows someone that works at a hydroponic store located in or around the Denver, Colorado area.
I am a soil grower and I am just getting into hydro, I want to learn more about it, but I want someone that knows how to grow hydro cannabis.
I went to...
Go to your local pool store and buy some cheap pH tester strips. It's only like 3 bucks
I use tap water, after 24 hours of evaporating and then I set the pH.
Have fun
