Admittedly, I'm not knowledgeable about any of this. I don't know the likelihood of gramine being in the final product or how toxic gramine actually is. I read on Wikipedia that "gramine, which, in sheep and to a lesser extent in cattle, can cause brain damage, other organ damage, central nervous system damage and death" (http://en.wikipedia.org/wiki/Phalaris_(grass)#cite_note-2). I'm just going to err on the side of caution.

Just read through the various phalaris threads, and various extraction teks, and your concern about gramine contamination in the final product will rapidly dissolve. It is very unlikely. Phalaris would seem to be your best option for a fast-growing, high-yielding, sustainable plant source of DMT by far.

One last question, why is the alkaloid content between the two acuminata samples so different? (https://www.dmt-nexus.me/forum/default.aspx?g=posts&t=27722). There's no telling whether you are growing an acuminata with %51 MTHBC or one with the %90 DMT?

Acacia acuminata varies, but the variant "Acacia acuminata inland form narrow phyllodes" is the known potent one.
There are some images on the nexus of the differences among the variants.

Looking for seed: http://b-and-t-world-seeds.com/

I personally like Psychotria viridis being that I am prone to growing tropical plants. I have one plant in a Water Farm by General Hydroponics that I have been growing for about a year. So far I have harvested around 100g but that was grown using 3 20 watt florescent tubes. In the passed 2 months I have harvested 30 of the 100g total after upgrading to a Halo 28w LED by Supergrow LED. It seems with better light I'll be harvesting 15g a month which is plenty for personal use in my opinion. It also sprang up 5 plants off the roots that I'll be placing out in the California sunshine to see what happens.

I'm thinking of the possibility of hybridizing acuminata (narrow) with another acacia that is small and fast growing. The goal of producing a fast growing, small plant, that can grown on balconies, indoors, in units etc, with the alkaloid profile of acuminata (narrow)

I'm mean, hey.. if people have pioneered cannabis in this same fashion, I don't see why the same principles cannot be applied to acacia's

I completely overlooked the broad and narrow leaf part! I ordered narrow leaf variety but it didn't say anything about it being inland, but I guess narrow leaf = inland acuminata? (http://australianseed.com/shop/item/acacia-acuminata). Am I better off opting for seeds that are explicitly from an INLAND acuminata.

The narrow phyllode acuminata is also known as inland jam. So it seems you have the species you wanted.

There's nothing wrong with the broad phyllode species (Raspberry Jam) either. I've heard reports of well over 2% from the inner bark. It just takes longer for the tree to mature before it can be harvested.
