Review on 🌱 OptiGrow PH Probe by Daniel Truett

When growing cannabis plants it is important to keep the PH in the 5.8 to 6.2 range. If they fall outside of these ranges, plants can suffer from nutrient deficiencies. Grobo automates PH ranges and keeps them in ideal ranges throughout the growing season. To get accurate readings, PH sensors need regular cleaning and calibration as part of maintenance. Over time, sensors can build up and become less accurate, so it's ideal to replace these sensors annually. These probes work great and your plants will appreciate that you're always up to date! Keep growing!
