i have used the hotwater treatment on 3 different Stctocardia species... following some advice i found on DG, the Net and from some instuctions that came with some I costata seeds... I costata have very thick seed coats too.

i put the Stictocardia in water that had just stopped boiling... left them over night and all except one so far have imbibed (is that the right word?) and they have all sprouted except for the S.tiliifoilia and the 1 S.macolusoi that didn't swell up... and i think thats down to after care.... as i had put the swollen S.bereviensis and S macolusoi seeds on top of the central heating radiator, which goes of at night and so cools down... however i put the S tiliifolia into a heated propogator which obviously stays warm constantly...
i'm going to try again using the hot water treatment with the S tiliifolia and using bottom heat afterwards, but allowing them to cool at night as Ron suggested...

i put four I obscura seeds into warm (not hot) water over night... they where softened but not swollen by the morning... i gave them all a little nicking and put them back into soak and by the time i came in from work they had swollen... i prefer to see if they swell up on their own before nicking as i find many seeds do not need it... esp the nils, and i'm beggining to suspect that fresh seeds need less help too....
