Definitelly Ipomoe Violacea but exactly this one
ILPT has vast experiences with this seeds because he was growing them few years and harvested thousands of seeds
Dose which will work and doesn`t cause much side effects was established for ilpt and friends somewhere btw 300-400 seeds(potency of seeds obviously vary but once you got your plant you will be familiar with alkaloid content and will establish your dose).
I think you are far too sensitive to psychedelics maybe you should start as low as hundred seeds and increasing your dose accordingly.
In colder climates like uk one can grow plenty ipomoeas, they doing very well. But the time is now, is may already. ILPT sprouting seeds somwhere in middle of april and this time of year he has already small plants which are ready to go out next to the big fence so they can twist around fence and grow wildly
In gardener shop you can buy 300 seeds for £1(careful those are treated with Hg salts, not for ingestion!!! ) plant them and each plant(if supported well)can yield 1500-2000 seeds
It`s cheapest psychedelic ever!!! For £1 with a bit of effort after 6 months one can end up with 1500 :shock: :shock: :shock: decent dosages
Ilpt`s best result was to step finely grounded seeds with grounded coffee
It seems it actually contain some Lsh or something like that cos it not as sleepy as Hbwr, although not analysis has been done to confirm this speculation
Other ipomoeas(purple, pink, white) are more weaker. Don`t now about rivea corymbosa.
