To perform a complete observation of marijuana plants from the time the seed pierces through harvest, only quality and tested equipment should be used. Experienced growers recommend using a backlit pocket microscope. This compact microscope has good magnification (60x) and is equipped with two bright LEDs that will help you see even the smallest details of your cannabis bush. You'll be able to accurately see the color characteristics of the trichomes (the fine hairs that stick out of the buds) and determine the time left until harvest.
Using a microscope, you can observe the transformation of the plant as it reaches maximum maturity. In fact, it is at this stage that the trichomes begin to change from transparent to a pale white color, changing to an orange-amber color. Using a pocket microscope you will be able to determine the time of harvest in time and get a good result.
