I used water bottles nutrients until I started wanting to know what I was putting in my plants. Boy, do they not want to tell you what’s in those water bottles…
Because other than PGRs you DON’T want, it’s the same damn 26 nutrients!
So why pay so much more for them?!
Dry nutrient salts from companies like www.hydro-gardens.com or Jacks are great for growing because now you can be sure about what’s in your nutrient solution AND what isn’t.
For example, I run hydro gardens’ 5-11-26 mix for hydroponics. Think of that as part A. I also add calcium nitrate. Think of that as part B of a standard two bottle nutrient line. Finally, I add epsom salt to boost magnesium and sulphur because it makes a big difference in the quality of the final product.
These dry nutrients are CHEAP and easy to use.
