I would be careful with smoke treatment. I did read some studies recently on smoke treatment of seeds and they appeared to show a reduction in germination when applied at the wrong strength, for the wrong amount of time, or even using the wrong brand of liquid smoke (apparently the flavor matters.) If it's not required, I wouldn't risk it.
Also I understood that D. cuneifolia was a winter-growing plant - I would expect it to go dormant during summer. Perhaps it's like pygmy sundews where it will only go dormant if conditions are poor.
