Garden soil and nutrient testing will be your biggest responsibility on a day-to-day basis while growing. Plants are generally pretty resilient, but they can develop some pretty nasty issues if certain aspects of their nutrition are out of whack.
Some of the most common things you’ll need to test include pH, PPM, TDS, EC, Temperature, and moisture. You won’t need to test all of these, but there are a few that are definitely important to measure regularly.
We’ll break this post into two sections - testing your garden soil and testing your nutrient solution. If you’re growing hydroponically, you’ll just need to worry about testing your hydroponic reservoir.
But if you grow in soil, you may need to test not just your nutrients, but your soil, and sometimes even your runoff.
