Thermometers & Hygrometers

Getting the environmental factors right in your hydroponic grow space is absolutely vital for success. Too hot or too cold and your plants will suffer. If the humidity level is too high then fungal infections can take hold. Too dry and plant growth will slow. Our thermometers and hygrometers will let you know when the air in your grow room is out of the correct range. We even stock an anemometer (or wind speed indicator) so you can measure exactly how well your extraction fan is working!
