A pH of 1 is considered an extremely acidic solution, and a pH of 14 being a highly basic solution. The thicker a line of nutrients is, the better plants are able to take up them. Almost everything can affect your pH level in your system. A paper strip is dipped into the hydroponic solution and it will change color. A pH range between 5.8 and 6.3 is good for most plants. Adding nutrients to the solution will help the PPM to get back to the expected level. The pH level tells you how acid or alkaline the water is. It is perhaps one of the most overlooked aspects of growing, but pH is very important (read: pH acidity: what it does to your plants) in hydroponics and soilless substrate horticulture.Soil has a good capacity for buffering pH. The nutrient solution flows through EC and pH sensors to make sure that the target EC and pH are maintained. In order to keep the pH levels balanced in your hydroponic system, first, you really need to understand the elements that will affect the pH levels. Testing Hydroponic pH Levels with an Electric Meter. 6.4-7.0: Acceptable pH Level. This guide will cover the basics of pH, how to check your pH, and how to adjust the pH in your hydroponic garden. In hydroponic gardening , the pH level of your solution is measured on a scale from 1 to 14.

It is best to maintain the pH between 5.5 and 6.5 for best results. If the reading is not at the proper level you need to adjust it using pH adjusters called "pH up" and "pH down," Depending on weather your reading is to high or to low. A substance that when added to water increases the hydrogen ion concentration will cause the pH level to drop. The optimum pH for marijuana in soil is around 6.0 â 6.8; The optimum pH for marijuana in soilless or hydro is around 5.5 â 6.5; If you grow in a soilless medium like coco, but with added organic matter (worm castings for example), you should consider aiming for a pH value somewhere between soil and hydro. In general, most plants prefer a pH between 5.0 and 7.5. Growing Medium. Source: Schon, M., 1992, in Proceedings of the 13th Annual Conference on Hydroponics, Hydroponic Society of America, ed. These pH testing meters can vary in price but are usually under $100. pH range is 6.0 to 6.5 (auto systems set at 6.3 pH) It is essential to have good oxygenation of the nutrient, the easiest and cheapest way to ensure this is to use a venturi on a bypass from the pump back into the tank. Most plants in soil grow best in a pH6.5 â 7.0conditions, while hydroponically-grown plants prefer slightly more acid conditions.
