Whether you indulge in indoor gardening, outdoor gardening or hydroponics growing, the
proper balance of the growing environment determines the health of your
plants... Here are some tools to help gain and maintain the proper balance your
plant's environment.
pH: (chemistry) p(otential of) H(ydrogen) TDS: total dissolved solids PPM: parts per million EC: electrical connectivity
The level of conductivity is directly proportional to the amount of salts dissolved in water. The conductivity of your nutrient solution is a measurement of its strength, indicated by the actual amount of salts dissolved.
Experienced growers suggest a pH level between 5.5 and 6.5 for most hydroponically grown plants. A dirty pH probe can skew the readings of your pH meter, resulting in a harmful growing environment.
Proper pH levels are crucial for healthy plant growth. A pH that is too high or too low can reduce the availability of some nutrients causing plant stress.
General Hydroponics Calibration Solutions are specifically formulated for electronic pH meter calibrations and designed for hydroponic solution determinations.
Model HI 98128 (pHep 5): This Hanna Instruments waterproof tester features a dual-level LCD that gauges pH level -2.00 to 16.0, and temperature from 23.0 to 140.0 °F (-5.0 to 60.0 °C).
Model HI 98129: pH/EC/TDS/Temperature tester by Hanna Instruments has a completely waterproof shell that also floats. It offers high accuracy readings with dual-level LCD readout.
Model HI 9813-6: We've used this meter in our shop for years and it's still in excellent working condition. The multi-parameter meter tests 3 of the most important factors for hydroponics: pH, EC, TDS and Cal-Check feature to assess calibration status.
Model HI 98311: Hanna Instruments DIST 5 EC/TDS/temperature tester is waterproof. It even floats. Guages temperature from 0.0 to 60.0 °C or 32.0 to 140.0 °F.
Model HI 991404: A large backlit LCD continuously monitors the three most important nutrient parameters in greenhouse, hydroponics and horticultural applications.
When growing plants using hydroponics and / or coco the pH value is vital to the garden's health. Hesi pH correctors provide 3 defined solutions to help you reach that optimum level of pH.
The Milwaulkee hand held refractometer is a precision optical instrument used for measuring concentrations of substances in aqueous solutions. It works using the principle of light refraction trough liquids.
Model SM100: This portable pH meter, with separate probe, provides the range of 0.0 to 14.0, with 2 point manual calibration, and accuracy of ± 0.2 pH.
Model SM802: The Milwaukee Smart 3-in-1 pH/EC/TDC combination meter with separate probe provides this range: 0.00 to 14.00 pH, 0 - 4000 ppm, 0.00 - 6.00 mS/cm, accu-
racy of ±0.20 pH and ±2% full scale for EC and TDS.
With the Sunleaves pH Expert Plus, measuring the pH in your reservoir is a snap! This handheld waterproof pH meter automatically compensates for the temperature of your nutrient solution to give you an extremely accurate reading.
The Sunleaves TDS Expert Plus is a highly-advanced handheld meter that measures nutrient solution electrical conductivity (EC), total dissolved solids (TDS), and liquid temperatures.
