Nice Pics.
I have arcturi growing in Belgium, it is not so difficult to grow them ones you now how
(Like always that is the case)
I stand my plants from October to April/May OUTSIDE in the cold and frost (-5°)
After the are starting to come out of dormancy i put them inside my green house, you can
leaf them outside, butt the grow better en beautifuler in a green house in the summer,
So thats it give them frost ore cold and they will grow like a normal Drosera.
The same growing technique, I use for D.anglica, D.filliformis var. filliformis, D.linearis,
D.anglica 'Giant', D.hybride (intermediaxfilliformis) D.stenopetala (only one left deu to bird ripping
out the plants out of the pot).
I cover my plants with wire to shield them from birds.
Hope this will help, I will try to put some picture up from my setup in my garden.
Greets,
