For optimal performance, re-calibrate your meters periodically or if testing TDS or conductivity levels in wide or different ranges. NaCl calibration solution. For use with any EC/TDS meter using 1000ppm standard.
Stakes play an important role in the early development of the young plants. Try our Bamboo Stakes to support your climbing plants such as beans, tomatoes, begonias and dahlias. Dark green stakes are 2', 3', and 4' long and come in packs of 25 each.
Hygrozyme® is a concentrated enzyme formula and is an essential addition to any grow system. With over 20 years of medical and horticultural enzyme formulation and production experience, SIPCO perfected a proprietary formula to help plants reach their full genetic potential. Hygrozyme provides a cleaner root zone by accelerating the breakdown of dead root matter. This process unlocks additional nutrients and helps plants thrive by stimulating new root growth.
The COM-300 is an advanced waterproof combo meter with superior accuracy. The meter measures four parameters: pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS) and temperature. Features include 2 different conductivity conversion factors to convert EC to TDS using the 0.5 (NaCl) or 0.7 (442TM), as well as selectable modes for measurements in the µS, mS and ppm scales. The meter incorporates automatic temperature compensation (ATC) to accommodate for discrepancies in temperature that would naturally occur, and also features digital calibration for easy and precise calibration that will yield better results.
A pH measurement meter is only as good as the most recent calibration. General Hydroponics Standard Reference Solution are pH meter calibration solutions that are available in pH 4.01 (pink) and 7.01 (green) and assure the accuracy of your pH pen or meter.
