Im not sure how much the eye piece is, i wont need it for a few more weeks, im gonna be harvesting the biggest plant before i get a zoom device. Most about half the hairs are orange so im gonna let them go one more week and pull it, as well as the ak ( i want to get the most sativa i can from this plant). but the other two i will most likely have a microscope for. I just need to muster up the courage to spend some money. Im on a real tight budget, hence the growing.
