.... which other Petiolaris Complex will tolerate temps as low as the 80's and 90's? I have a fishtank and a submercible heater, and a fluorescent light set up with lowland Neps, B. liniflora, and a D. lanata. I just got hold of a piece of styrofoam that I will cut to size and contour of plastic plant pots so that they will float on the water. Should the Petiolaris plant pots be submerged in the water at all and by how much or should the bottom of the pot be at the surface or slightly above the surface and by how much? Would D. ordensis be okay in this temperature? What other Australian sundews would benefit in this glorified terrarium setup?
