Sub nutrient solution

Hi Ron,

Does the nutrient solution have a limited life time?

Is it possible to recycle the water (economically)?

Tks for your answer. Mike from Botswana

What happens over time is even though you get a correct PPM reading the N P K can get out of whack over time and the only thing to do is change your solution. Use it to water your dirt plants because they can handle it.
