I dont think that will work bro, as mentioned above radio shack sells
a 60x microscope for 10 bucks! well worth the investment. i tried a
mag glass also and there is no comparison! Get the microscope!!!
do a search on trichomes and youll know when to harvest. if you want a head high harvest when trichs are cloudy. if you want a more
narcotic high, wait till they turn amber. hope this helps!
