Masdevallia herradurae is a good grower and you should be doubling the size of the plant about every 6 months
...I havent had much luck with many species. I got a few from andys. to be honest, they were so ugly when I got them I threw them away in a few months of them hurting my eyes. freeking crap from andys. oh some love it. they can have mine too. I dont need to buy crap that I can grow myself. damn things looked like they been run over by USPS not delivered by them.
Wee see how we do with the larger plants si senor
