Apparently deciding the time to harvest marijuana is decided by the color of the trichomes, which are too small for detail with the naked eye. A magnifier of 30x to 60X is required. Economic viewers of this sort have a small depth of focus, which make using tedious and difficult. My improved method is to use a white background, place a sample to be viewed on top, covered with a flat plastic piece. This produces flat plane making focus easy. A glass slide would be ideal if one has access. Two types of readily available hand microscopes are shown which are 30 and 60 times magnification.
