I decided to have a go at something a bit different , so I bought 5 seeds from silverhill seeds, when they arrived one was crushed leaving me 4. In the past I have tried and failed with roridula gorgonias. After doing some geeking out I had a plan , first off I scarified the seeds with some very fine wet and dry paper , just on one end ( first time I have done this) then for the smoke treatment. I dried a small amount of peat under the grill then set it smouldering and put it still smouldering into a glass bottle, let the bottle fill with smoke and added a small amount of rain water , so the rain water infused with the smoke and burnt peat, then added the seeds and left to soak for an hour or so. The seeds were then placed on a media of 1/1 peat and sand and lightly covered, also watered with smokey water. I kept them damp and after a couple of months all 4 seeds are showing signs of life , I have transplanted the largest into a mix of 1/1/1 peat/ sand/ perlite . Here's the most advanced

Nice germination rate! I saw the seeds in stock at Silverhill earlier in the year but didn't jump on it. I probably should have.
Where did the mold start? What I've discovered growing Roridula gorgonias is that you should avoid water on the leaves and overly humid environments as the plants are very prone to botrytis infections. I ended up having to chop the growth point off my plant to stop an infection, but it's growing well again, though it was nearly a year old when that happened (I did not start the plant from seed myself.)
The two that didn't make it never got as far as producing any leaves , they had only just germinated then the dreaded mould got em. I didn't try to raise humidity as they were in an open tray , I think they would of been better off in my outside open fronted propagator with more airflow and light. I hope to update this post with some better news soon:-(
I'm thinking the same thing Fred, I will have a go with the smallest seedling and see what happens, I also considered finding some other insect poop such as caterpillar , but maybe I'm not all there:-) edit ...just tried the diluted fertiliser out a syringe and the water tension made droplets too big and they rolled off , I have some horticultural soap would that break down the tension and reduce droplet size or poison the seedling ? I also inadvertently fertilised the roots with the droplets that rolled off , what a pioneer;-)
The only survivor is slowly growing over winter, I have the lights on for 10 hours a day in an attempt to replicate its natural conditions. From what I've read it should speed up with some warmth when I place it outside in the spring
