So, I have a varied collection of sundews (Binata, Aliciae, Rotundifloria, Filiformis 'Tracyii' and 'Florida Red', Venusta, Spathulata “Pink Flower", Capensis “Typical”, Capillaris, Adelae, Intermedia, Roseana) and I have difficulties giving them the right conditions to produce dew.
I read on Jacob and Jeff's site that the secret is light! However, it seems when I give them the light my Sarracenia receive, the dew-producing stops. Dew producing definitely stops in low-humidity too.
Before my collection recently expanded, they produced dew under a sealed greenhouse (made with packing tape, chopsticks, and saran wrap), and under the bright, direct light.
Since putting them in a portable, shelved greenhouse, they haven't produced any dew at all. I mist the inside of the greenhouse atleast twice a day as well.
Any help is appreciated. I live in Florida.
