What are you planning to do with your morning glory seeds? I wouldn't suggest eating the seeds if your choosing to grow them for their psychoactive properties. The seeds are poisonous, and do have a tendency to make you vomit uncontrollably for hours on end. I've experienced this myself when I tried morning glory seeds and the experience really isn't worth it!! Lol.
Neptune rules this sprawling plant that can overtake a fence like a tidal wave.
So I whold say to do a spell with the seeds/plants on a Neptune hour/ day
I suggest you use a depression / nervous energy / addictive behavior spell
Blessed be :) )0(
