I've collected an array of scopes to admire those glistening trics.......for a simple quick look, the 30x lighted jewelers loupe ($3.60/ Amazon) is great! But when checking for harvest timing....ie, seeing trics well enough to SEE the cloudy or amber, whichever you harvest by, you'll need the 420 scope.....60-100x....I use a 10x when determining sex early.......
All are very cheap and open up an amazing world of sites previously unseen.... I sometimes spend 15-20 minutes just looking.....MJ is a beautiful plant and brings you a treat if treated well....
