issue cumari pollux

Hey,

does anyone have trouble germinating cumari pollox?

i've got mine in soil, unther a dome, at 29 degrees Celsius for 30 day's at this point.

today tuned it down tot 25 degrees.

cheers. Stijn

Germination efficiency is not a property of the variety but critically depends on the seed storage conditions. Pepper seeds lose viability really fast when stored without protection from heat and humidity. Optimal conditions would be heat sealed with drying agent and oxygen absorber in the freezer. But just keeping them in a fridge would help a lot.

thnx. i doubt storage is the issue. all others variaties from the same batch sprouted 100% and within a week or so. So i wonder because this is a kind of different variety, 29 degrees might be to hot. Has anyone grown this one?

A general trick that I apply to uncooperative seeds (seeds in general, not just peppers) is to change the growing conditions from optimal to unfavourable for a while. I let the soil dry out completely. In your case, I'd switch of temperature control as well. After some time, reestablish optimal germination conditions again.

I think this is great advice overall but the first sentence is patently untrue. It is for certain a property of a few species of Capsicum including C.rabenii,the species Cumari Pollux belongs to. There is empirical evidence all over the internet…a lot here as a matter of fact.

I think your information on storage is as sound as possible and even more important for these wild species since there are not as many outlets to source them and most are untrustworthy.

I believe from little experience that this temperature can be an issue at times with wild species. I personally have had far more success with lower temperatures. Try 22-24C for a bit or fluctuate between that and your typical temperature. As mentioned before in this thread,those fluctuations in temp and moisture have triggered success for many of us with these more difficult to germinate species.

Good luck. When you succeed you will be happy with the beauty of this one.

Sounds like a plan. Many thanks.
tuned off the heat for now, so they will be at 20 degrees. this week i will try move them to 24 en 29 degrees and back. We'll see what happens.
Would a fridge night of about 5 degrees be a terrible idea?

still no result. temperature change did not yet doe the trick. starting to think bad luck.

You are only as good as the quality and viability of your seeds.

Also, what time frame are we talking here. If you are giving up on C.rabenii in 30 or 40 days,odds are you are throwing away perfectly good seeds. If I had one answer for having success germinating wild Capsicum seeds it would be patience. 90 days is not uncommon in this realm.

did not decontaminate. I never had contamination before.

if the deno seeds go rotten it might be this. humidity i find difficult to say, other seeds under the same dome did fine.

I blame George Clooney, just because i can, and i dislike Nespresso Coffey.

I have no idea what de deno means or how it works. The same sowing method for the other 40 or so species of pepper will work for these with some minor shenanigans. How were the seeds sourced? Are they old or from grifters? Do you see any gnats or gnat larvae? They can and will destroy seeds that take longer to germinate as will rot from being too wet. What are your temperatures like outside this time of the year? I have had success have had success moving mine outside in natural temp cycles.

Hoping you get to see these grow. There are some within this species that produce stunning plants. All different heights and habits.

The deno methode is to wrap some seeds in a paper towel or coffee filter in stick it in a zipplog bag.

i propagate at 28 degrees Celcius. Cant tell anymore about the previous seeds. discarded the lot.

Friday will be the 7th day of the new batch. hoping to see some movement.

today replaced the paper towel of the deno. seeds are looking fine, but no germination yet.
from this day forward will be singing Johnny Cash Ring of fire to the seeds every day. Cant say it will do the trick, but it is not likely to kill them.

any song requests?
