16xmagnification jewlers scope

I was just wondering if a 16x magnification jewlers scope would be strong enough to see the trichome's and judge if the plant is almost done.

that is the best 12 dollars you can spend on a scope. It works great and can easily see the trichs color

Do they sell them in there stores as well? or just online

I bought mine in the store, I guess it depends on your local store. They could always get one sent to them for you to pick up so you can avoid the shipping charge

Alright thanks Tom ill have to check into that.
