looking to buy a water fitration system for my grow. I am not sure what type of filtration is best for my plants. I was looking at a few different ones that are inexpensive.
My water PPM unfiltered is 300 pm.
I have heard you want the ppm of the water to stay around 150 ppm, but if I get the 5 stage reverse osmosis it will bring the ppm to about a 008. Would Cal_Mag make up for the minerals lost? or should I gow ith a system that doesnt filter out as much ppm? EExamples of some I am looking at
