I have read how Tamlin gorws this in "sphagnum slurry". Any more info? Eg. water level, light, temps, etc. etc?
Mine are growing well in coomparitively low light about a foot from twin four foot flourescent tubes, one cool white one balanced spectrum (grolux). *The medium is supersphagnum (the kind that comes compressed in cubes like Phil Wilson has). *They are in shallow white plastic trays about 120 mm long and half as wide (got about 15 at a yard sale!). *The slurry is allowed to dry to wet, not less, and then is flooded to the brim. *The transpiration rate is good and I must reill about every other day. *Temperature is whatever the grow room is at: 50F min. winter, 70F max * In the warmer months it gets up to 90F with a good night time drop except in the hot months (which didn't come this year). *I use rain water. *Monthly I add some water from a U. macrorhiza site near here. *Ummmm, what else? *The plants are in an open aquarium with the light on the top, no glass or plastic between the palnts and the light. *Humidity is always at least 40%, and higher in the warmer months. *I thought this species would be a real problem, being a lithophile, but it has responded remarkably well to my culture. *It is a very interesting little Utricularia, and the lolons are very distictive. *I grow 2 forms, one has smaller lolons and the other slightly larger. *Currently some of the lolons are yellowing, and I am not sure why. *Lets hope it isn't a trend! *I hope this helps, and good luck with your cultivation.
