Mark,
You are right in assuming that tuberous Drosera seed will not germinate
until the temperatures get lower. I have not tried smoke treatment for
tuberous Drosera seeds and have only tried giggerellic acid once on D.
fimbriata seed. The gibberellic acid treatment seemed to work well
giving me good germination within about 8 weeks (not bad for these
Drosera).
The usual time for germination is anything up to a year untreated. For
treated seed you ought to see results within three months or less,
assuming the seed is still viable and the conditions are right.
Hope this helps.
