What Kind of Water to Use for Marijuana Growing
Watering marijuana or any other plant is important. It keeps plants hydrated and provided with the necessary nutrients. Watering marijuana requires a specific type of water to provide it with the nutrients it needs for it to thrive and produce great yields.

Knowing What Water Contains
For starters, the use of tap water may not be a problem for most indoor marijuana growers. But water, as in H2O is just 2 parts hydrogen and 1 part oxygen which marijuana plants would need but it is unusual to find water this pure nowadays. City water has already impurities dissolved and suspended all over which can be a problem to the growth of your marijuana plant. Knowing the component of your water can help best in resolving your marijuana water issue starting with the basics, what is in your water?
Minerals on Water
TDS or Total Dissolved Solids is the number of solids, probably minerals, dissolved in the water or any other solution that can’t be taken by an ordinary filter. You can measure the TDS of your water by using a TDS/EC meter by having two electrodes placed in the water then passes AC voltage between. The meter will read the amount of current that passes through the solution which indicates the conductivity of the solution and converts that will display as parts per million, most commonly known as ppm. If you could determine the baseline TDS, you can later decide which amount of nutrient solution you need to mix depending on the dosage strength your fertilizer suggests.
Acidity and Alkalinity
Another thing to consider is the pH level of your water for this makes a huge difference in the success of the growth of your weed. PH or potential of hydrogen levels is the measure of acidity or alkalinity of a substance. Technically, this indicates the concentration of hydrogen ions in the solution. A PH of 1.0-6.9 is acidic, 7.0 is totally neutral while 7.1-14.0 is basic. You may use litmus test strips in measuring the pH through reading the corresponding colors but you can use pH meter to be more accurate. Most plants prefer a slightly acidic pH, as for marijuana plant, the safe zone pH is between 5.5 and 6.5. Weeds might not be able to absorb all of the necessary nutrients if your pH doesn’t stay in the safe zone.
Some would prefer to use distilled water but the cost may be heavy. One way of resolving issues with tap water is by using water filters. The best filter tested by many pot growers is called Reverse-Osmosis. Models have been usually designed under-the-sink that can easily be purchased for around $200. This may require cleaning and filter replacement at least once a year.
However, the downside with Reverse-Osmosis is the quantity of wastewater emitted during the process. This can be reduced for up to 85% with the help of a permeate pump which can be installed in your Reverse-Osmosis system. This device can operate as a non-electrical energy recovery device that uses the available energy from the brine water after the flow restrictor which then forces the purified water into the storage tank. Nevertheless, it is not recommended to use plain Reverse-Osmosis water in a hydroponic medium for flushing. The hydroponic growing system of marijuana is the art of growing marijuana in either a bath or a flow of highly oxygenated and nutrient-enriched water.
