Growth Technology Nutrients & Solutions

About

Growth Technology is a British manufacturer that most growers know for the unglamorous bottles - pH adjusters, buffer solutions and calibration standards. That is not a criticism. Meter care is where accuracy actually comes from, and this is the range that keeps UK grow rooms measuring correctly. pH adjusters: Growth Technology pH Up and pH Down - see all pH Up and pH Down . Calibration and buffers: pH Buffer 4 and Buffer 7, plus conductivity standards at 1.413 and 2.76 for EC meter calibration. Browse calibration solutions . Probe care: pH probe storage solution (KCl) and probe cleaning solution in 300ml - the two bottles that decide how long your meter stays accurate.

Formulex is the quiet star - a single bottle that will carry seedlings and cuttings through their first weeks without burning them, in any medium. And the calibration range is the reason your meter still reads true a year after you bought it. Growth Technology FAQs Why store a pH probe in KCl solution rather than water? Plain water leaches ions out of the glass bulb and permanently degrades it. Storage solution keeps the reference junction working, which is what stops the meter drifting. Which conductivity standard do I need? 1.413 is the general-purpose standard for most grow room EC meters. 2.76 suits calibrating at the higher end if you run strong feeds.
