Water Quality
We all get our H2O from somewhere and for those growers using municipal taps or bleak groundwater, testing and correcting water issues is the first step in addressing issues in your garden. Water quality is important to your plants and knowing the pH and TDS of your source water is a great step towards mastering your indoor gardening skill. Whether you need a meter to measure, an RO system to clean and purify, a chiller to keep those temperatures down, or just some pH Up and Down, HTG Supply has you what your water needs to succeed.
