I grow some of my Drosera and Pings (all tropical) in a large aquarium, and I have 2 twisty flor. bulbs and one big long one. The long one's bulbs are only about 3 months old, and the temp gauge says 80 f all the time, and is this ok in winter? And, in summer, who knows what the temp could raise to? If so, how would I go about cooling it? I thought of putting ice in there, but I dunno. Does anyone have any ideas?
