== pH ==
The ideal pH of the water applied should be between 6.2 and 6.7. Note to also measure pH after adding [[nutrients]] to the water. If it's too high for too low, the nutrient intake will be blocked. This is an especially important rule to observe when using nutrient formulas as to not waste them! It's important to note that pH is a logarithmic scale, meaning that 6 pH is 10 times more acidic than 7 pH.
It's a good idea to check your tap water with a digital pH meter as it will vary depending on your geographical location. If water is too alkaline (pH too high) a few drops of lemon juice or vinegar can be added. To increase pH you can add dolomite lime.
=== Reverse Osmosis water ===
Some growers don't have access to pure water and use water filtered by reverse osmosis (RO).
ISBN 13: 9781937866358</ref>. This technique of filtering removes almost all contaminants and other particles larger than 0.001 microns. In other words, this removes almost all nutrients from the water. RO water can be purchased or created using specialist hardware.
==Wet-Dry Cycle ==
[[File:WaterStake.jpg|thumb|282x282px]]
A form of automatic watering that allows the plant to “drink” water through a straw. Ideal if you need to leave a plant unattended for a few days.
