Hi, I'm a complete noob to this. I have a real urge to try DMT(for spiritual purposes) but don't quite have the balls yet to buy DMT from a dealer. I'm planning to cultivate, extract and consume the DMT all under 1 roof for a start, and try to do everything outside of my roof as legally as possible(for now).

What would be the fastest way to cultivate and extract DMT inside my house? I thought about buying MHRB but its a bit eco unfriendly, and in my country(Australia) its illegal to possess any bark or plant substance which has DMT in it(which means buying over the internet is a no go for now). I also thought about finding some acacias around my place and just cutting the bark from them, but this is a bit eco unfriendly and too damaging for the environment. It would be too slow to grow acacias in my house and then get the root bark from them(takes at least 10 years to grow? And that's just for 1 harvest!!).

I'm wondering if there's any way to get some plant material(without buying online) quickly and in a sustainable way in NSW? After research one potential option is cutting leaves and branches from some sort of acacia, but the research suggests that there would be almost no DMT inside the leaves and branches, and the DMT is only in the root bark(I read a study that said up to 0.03% inside leaves of acacia maidenii, one of the most DMT rich acacias in Australia).

Any tips for a noob? How would you start in such a situation?

The answer to your question is on this website, and many others. It's worth spending more time reading.
There are many acacias that have dmt in there Phyllodes and branches. You don't need root bark.

Please read the 100 page improving acacia knowledge thread.

In response to your post I would suggest your best bet is to locate some wild acacias, then visit the area after wild weather. Some will be uprooted, or blown over, or branches snapped. Use this material.

In the meantime, plant some seeds to get the ball rolling. Very easy and fun.

Welcome to the Nexus!

I'd suggest first of all read the Attitude page which was linked in the welcome pm you received. It contains the rules of this forum, including not talking about buying/selling/sourcing DMT or dried plant material like MHRB.

Then I suggest you read the FAQ because it has a lot of questions such as how to find a plant which contains DMT, how to extract, etc etc.

Spend some days/weeks reading first, and what you can't find answer to, feel free to ask.

Good luck!
