Watering and Feeding Utric's Indoors.

[Wort]

Are there enough microorganisms in stored rainwater to keep indoor Utricularia spp. colonies happy? Does anyone culture Paramecia or anything to add periodically?

My water is stored in a water butt, fed from the gutters around my slate roof. There are mossy patches here and there so I am hoping that there will be enough microorganisms. What do you ladies and gents think?

Cheers from Bill.

That should be enough.

They don't need much to thrive. 
If you want, you could do some culture, though don't add too much or you might overwhelm them .

I don't feed my Utricularia anything specifically.

Thanks, that's put my mind at rest. Have a good afternoon!
