I've been very interested in Iboga after reading about it. I wanted to order some bark and do an extraction to have an experience, even though I don't really have a need to. I understand it's not recreational, but the intensity draws me nonetheless. I couldn't find a source for it that wasn't extremely expensive, so I got the sense that it's somewhat endangered; which is a shame if it has as much potential as they say. I feel that entheogens are very beneficial and sacred entities in our world that anyone should have access to. While it's great that they are getting more attention, I'm worried that they're being carelessly overconsumed without thought for their sustainability.
I decided the best and only option was to start growing some seeds. I've heard that Iboga seeds are very difficult to germinate. I followed the best advice though and it worked out well. The seeds are most viable when still in the pod, and the vendor I found shipped single pods wrapped in moss. I think it took about 3 weeks to arrive, and had instructions for keeping the mossy rotting pod in a bag for 3-6 weeks until the seeds sprouted. There's a whole bunch of other tips to boil the seeds, nick the coats, etc. but I guess the best route is to just wait for them to sprout from the pods. I checked the seeds and they looked just like the pictures and moisture was good, so just put the bag in a drawer and literally forgot about it for over a month. By the time I noticed it again a couple weeks ago, 6/6 seeds crept out of the moss toward the ziploc with huge radicals and cotyledons. (No pic)
I was surprised and quickly prepared a seedling mix for it, 90% coarse sand and 10% vermiculite. I was a little rushed to get them transplanted, but decided this would be fine for its inert drainage requirements. I'll see how it goes.

I found them a little late, and the cotyledons on all but 1 of them were badly withered. I wasn't sure whether they would survive at all but this species appears vital. They greened up after a couple days and have grown some and begun new leaves.

This guy's cotyledons did not recover at all

But is already showing new signs of life.

I have them under a 6500k Daylight fluorescent light, in a bin to contain the humidity. I put 2 inches of soaked perlite in the bottom of the bin, and the humidity stays around 90 which may be a bit too much. They're in little biodegradable potting cups, for easy transplanting. But mold has taken over the bottom quarter of the cups, which I'm not sure whether to care about or not. I'd pot them into something larger with soil, but I'm not prepared to mimic the humidity on a larger scale.
I plan to keep them inside, maybe take them out next summer some when they're stronger. But I live in US zone 5a, so planting isn't really an option.

Overall, the process getting this far was pretty easy and fun. I encourage anyone else to get some seeds started if you support entheogens and plan to try them or revisit them a few years from now.
