Hey everyone - Calling all sundew experts!
I have four nice pygmy sundews, and I'm trying to get them to produce some gemmae so I can sustain their colonies. To achieve this, I've gradually lowered the photoperiod down from 16 hours to 9. I plan to leave it there until mid-February and then start ratcheting it up again.
This may or may not be pissing my other plants off. I have a number of tropical dews, pings, etc. in the same rack along with my pygmy dews. My pings look VERY happy (even my struggling P. moctezumae is showing signs of recovery!). But so far, my D. adelae, D. alicae, D. spatulata "Fraser Island," and D. venusta appear to be in various stages of decline. I'm quite concerned about the D. adelae and D. alicae; the D. spatulata and D. venusta just aren't as pink and dewy as I'd like them to be.
For those of you that grow sundews under lights, have you experimented with photoperiods this short? Might the plants be happier if I simply let them dry out a bit more?
I'll post some pics up soon so you can see what the deal is.
