Gramm. like lots of undirect sun (mine get direct sun for only a little bit in the morning). Even then, it does look like it gets alittle sunburn. They are a very thirsty orchid and like lots of water. Gramm. actually can grow semi-terrestrial on decaying tree trunks. I grow mine in straight moss and a vanda basket.
Thanks Wjs2nd,
It does seem to be pretty thirsty. I moved it to an indirect light spot in the some room so we will see what it thinks of that. Can you tell me anything I need to watch for?
