Find an easy to use scope for plants
Mine is 25x to 60x zoom. Its easy to see trichomes if you can hold it stil, if not cut off a small piece to view.
The trichomes grow on everything you see and are evenly spaced and look like a tall mushroom forest. Their mushroom tops are you ripeness. Clear is not ripe. Milky white tops are prime harvest and amber is where they start to degrade their thc potency but change to other potency such as couch lock or zzz. Same strain with no amber will be a very uplifting positive most effective buzz. 50%or more amber is a stronger effect in the sit your arse down kinda way. Everyone has their own preferences
If its high Munchy effects i go for more milky. If not i like at least 25% amber or more.
