I'm not a big fan of the carts but they're convenient sometimes if I'm out and about. I mostly vape flower. I had a lemon cart one time that tasted amazing, that might've been the best tasting cannabis product I've ever had. That or some plain ol' Lemon Kush
(I like lemon lol)
Are you using those dry herb vaporizers? If you like a good energizing strain with a lemony taste check out Super Lemon Haze.
