Hello and welcome! :)

Welcome to the board. You don't really need a bloom booster fert. the rule of thumb for most orchids is feed weekly weakly. Just see if you can find a good orchid fertilizer and don't use the full strength.

Den phal hybrids originate with Den. phalaenopsis and Den bigibbum (which some say is Den. phal.) These are plants native to Australia. Read up on them and you can see what climate patterns they have. Of course, other species are mixed in as well, and orchid hybrids tend not to have the rigid seasonal growth pattern of many species.

Brilliant, thanks for the advice guys!
