how many times zoom would i need to see trichomes properly and clearly iv tried to find a hand held microscope but i can only find those real hard out microscopes they have in labs and scientists use lol i saw some magnifying glasses but they all like toy ones they dont have much zoom so i figured if some can tell me how much zoom i need from a magnifying glass then i could just go and walk into a shop and tell them exactly what i need and get it hope this make sense cheers guys for any help
