PH Test Kit – Liquid 6 – 7.6

£2.50 incl. Vat
Low or high pH levels affect the availability of the minerals required by the plant. The correct pH range for hydroponics is between 5.5 and 6.5, for soil it is not so critical, but generally around 6.3; outside of these figures nutrient problems will quickly occur as minerals become insoluble. The nutrient strength needs to be matched to the current stage of plant development. Too high a concentration can quickly burn a plant, whilst too low produces pale, weak growth. Measuring is knowing. Good results are attainable by anyone prepared to stick to this rule. Whimsical guesswork rarely leads to success! The Nutriculture pH Test Kit allows quick and accurate monitoring of pH levels in your nutrient solution. For accurate acidity testing follow the procedure below. •Take a 2ml sample of solution from the tank in the test tube provided. •Add 2 drops of reagent. •Shake the test tube and compare the colour against the test strip to determine the acidity. •Discard the test solution and rinse out the test tube. •Adjust the pH of your nutrients and retest if neccessary.

Growth Technology Conductivity Standard – 250ml

£5.00 incl. Vat
EC meters should be calibrated regularly. Conductivity Standard is a solution with a known, fixed conductivity (EC), it is used for calibrating and maintaining the accuracy of your meter. Please follow the instructions that come with you EC meter and always rinse the porbe after use to maximise accuracy and life of your device. Just pour out what you need into a measuring cup, and use this to calibrate your pH meter. After calibration you must discard the used solution. Do NOT pour back into the bottle as this may contaminate the bottle and make the solution inaccurate.

In just one glance the Guardian Monitor measures all three critical parameters to successful growth; pH, conductivity and temperature. Seasonal changes, sunlight hours, wind, inherent plant growth; from vegetative to fruiting; are all influencing factors to plant growth success. More importantly...these parameters change the plants uptake and need of water and specific nutrient elements. The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, enabling the grower to optimise these parameters as the crop progresses through each growing phase. The Guardian removes the complexity of how each parameter relies on each other for outstanding growth. Our innovative monitor is a new method to help guard the success of your crops with immediate and accurate results. A flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively. With our Guardian monitoring your crops 24 hours a day with a built in alarm system
