one word of advice...dont replate too soon.wait until you can see the individual little sizeable protocorms..if you dont wait you will have to replate several times because too many protocorms will end up in a flask...you want to leave enough room for them to grow to a good size to survive out of flask and also the less you replate is the less you risk contamination...4mm-6mm is a good size according to species..i made that mistake with a remake of Trichocentrum xhaematochilum last month so i have like four "mother flasks" all over again(replates) ahahahah
