To take control of your cannabis grow, you need to be able to take certain measurements! Here we provide our recommendations for all the different types of measuring devices for growing cannabis indoors. We include the hygrometers, pH meter, EC/PPM meter, LUX meter, and Scale that we use in our cannabis grows! Take control of your grow and get the right equipment to measure Temperature, Relative Humidity (RH), pH, Electrical Conductivity (EC), Light, and the weight of your harvest!
Thermometers & Hygrometers
Ambient Weather WS-10
Hygrometers with Probe
Mini Hygrometers
Mini hygrometers are particularly useful for curing because they can easily fit inside the jar with your buds. They also come in handy for seedlings in humidity domes.
Caliber IV
Inkbird ITH-10
pH Meter
The technology involved in measuring pH is sensitive and sophisticated. There are numerous cheap pH meters on the market, but these are shortlived and unreliable. You do not need the most expensive models, but it is worth investing in a quality pH meter.
Apera Instruments pH20
pH Calibration Solution
Electrical Conductivity (EC)
Measuring Electrical Conductivity (EC) is absolutely critical to managing your fertigation strategy and nutrient solution strength. The technology involved in measuring EC is rather simple which means that you do not need to invest in an expensive meter. However, if you use one of these meters, the water should be measured at about the same temperature that it is applied to the plants (about 68f/20c).
EC/PPM meter
Measuring Nutrients
10ml Oral Syringes
Light Meters
Light meters are used to evaluate the light distribution in the grow space and to determine the best height to hang your light above the canopy. This is not a required tool. Many growers can do fine following general guidelines, but if you want to dial in your grow you need to be able to measure the light.
Lux Meter
PAR Meter
Scale
This is not required, but you are going to want to know how much you harvested!
Ohaus CL201 Compact Scale
