Soil:
A 2:1:1 ratio of peat, perlite, and sphagnum works well for most species, except the aquatics which need a little peat in their water.
Watering:
Never let them go dry, unless your plant originates from SW Australia, in which case they require a summer dry period.
Light:
The terrestrial leaves have the best color in high light. There's a fine line between pretty and dead, however
Environment:
Utricularia grow on 6 of 7 continents on earth, so 1 all around climate is impossible to re-create. Some freeze in the winter, some suffer through desert conditions in the summer, and others grow in tropical jungles. Try and get your growing area between 40% and 80% humidity and 60-85 degrees to keep the widest variety of species.
Cultivation:
Quite easy-some can become weeds! All the more common ones (U. bisqumata, subulata, sandersonii, etc…) are impossible to kill!
