Seedleranswered grow question 25 days ago I have a 1 euro Loupe, i can also clip on my phone, super cheap but obvsl works. Most of the time i just use the macro function of my smartphone. Or take out the big boy cam with some macro rings. But all of that works to check for trichomes. Even the cheap digital ones are great. If you have a somewhat decent phone, just buy something to clip on and do it that way
Have fun, i loved looking at everything in detail when i started out !
