If you do not keep humidity over 90% and maintain the soil temperature at 20 - 22 degrees centigrade the you will not get better rates than that. Remember this is a vine originating from the Philippines - so you have to get those weather conditions. Try closing the cuttings in large plastic bags and if you can get a soil warming cable to warm the underneath of the pots you should improve your success rate.
Do not throw the seeds away - you can still save them. Get a 2% hydrogen peroxide solution and put the seeds in it. Make sure all seeds are covered with the solution. Leave in a dark place for 24 hours. The container should be closed but not airtight. After that put the seeds in the soil immediately. When you water the soil to keep it damp, use the peroxide solution. Keep doing this until all seeds sprout.
thanks for the advice, but its way too late, the seeds started to smell really bad, so i took one out of the pot and gave it a squeeze and it just mushed up in my hands.
they are NOW under a 400 watt HPS light in the cupboard, i put the seedling pots in clear plastic boxes, the temps area round 35c, i dont know about the humidity though.... may take around 2 weeks to show any sign of them rooting so ill keep my eye on them and report back when something interesting happens.....
Best of luck dill786. I would have soaked them in 2% hydrogen peroxide before planting and used sterilized soil. From what I read the seeds are not hard to germinate provided you give them plenty of moisture and keep them at a tropical temperature (above 22 degrees centigrade). So I suggest you try keep the pots warmer. My concern is that these came with mould already - that will continue to attack the seeds and infect the soil. I suggest you use 2% peroxide solution to soak the soil a couple of times. It won't harm the seeds at all.
I am still searching for seeds or cuttings myself. help anyone?
