My questions are what sorts of ambient temp fluctuations in the growing areas? I have mine outside and they just exist. never seem to do anything more than just that. Dry dormant period did that happen? I tried to give them that, but welll stuff happens.... I saw them blooming at Peter's Place, and for Bob Z. I have often wondered if I don't get cold enough but it they are blooming at room temp ambient conditions it sort of suggests other wise.
True Bugs really Suck
Just my 2 cents.... I think its likely dry period.
Ive been letting mine dry to the point of the sphag being crunchy for the last few months before I water. This is also their natural time to be umm dry (relatively speaking)
Back about a year ago I posted the climatic data for most of the major Tepuis. Pretty much constant as far as temp, some drop but nothing to speak of... but what was seasonal was their dry season (relatively speaking) that occurs from Oct. through March.
Additionally, "The genus Utricularia - a taxonomic monograph by Taylor, Peter. (1989)." states that U. reniformis can be observed in-situ flowering from Oct. through March.
I dont think that is a coincidence.... Realistically, how could pollination occur when youre getting multiple inches of rain per day.... it would seem risky for the plant to expell that much energy any other time of the year.
My vote is dry spell, maybe even dry spell and a oct. through march time frame.
But me no utric daddy.... just making assumptions based on hillbilly logic. May be quite a bit of variation within the species too.
Maybe not the exact location, but I think its still valuable data...
Only one variable has a dramatic and predictable shift

Here's the link to another thread on this topic.
caracas is unfortunately nowhere near tepui-ville, your best bet would be somewhere around the ball park of Santa Elena de Uairen-- dont have yearly rainfall schematics, but this current month's is quite interesting: http://www.weather.com/weather/monthly/VEXX0034
take it worth a grain of salt. most orchid utrics live near tepuis, but not all of them...
Found a pge that shows the averages from your link jon... http://www.weather.com/weather/wxcli...graph/VEXX0034
Again temps pretty constant, rainfall has a seasonal variance.
Ron, I doubt its as simple as just let the plant dry out. If it was it would be standard operating procedure by now for growers.
I wonder if dry and timing must go together...
maybe both variables need to be in alignment for the process to begin?
