Perlite. You will need to provide nutrients yourself since perlite has none, but it won't compress, provides good ventilation and it's easy to clean when harvesting.

Yes, or something like gravel or hydroton.

could you expand on that a little piratebOb , i myself am trying to grow mimosa as a bonsai and training the roots for harvest , would really appreciate if you would share your technique

also one question i had to ask , does anyone know is it the main tap root that is harveseted or lateral roots ?

since training a bonsai means to cut the tap root , to promote thickening and growth of the lateral roots , , i have no idea whether its the tap root that needs to be harvested or lateral or both ?

do NOT harvest the main tap root..well maybe if you want a bonsai..

You can also do this instead..what I am doing is bending the tree over to promote lateral branching..this way you can get the tree to spread out indoors like a bush to maximize space and stop it from just going up..of course you need a larger pot for the roots but I dunno how much your gunna harvest anyway from a Bonsai without killing it..

here is pics of what I am doing..so far its working..

Somebody over at thenook attempted something along these lines with Hostilis in pipes. They found it unsucessful in that the roots were feeble and the plants did not thrive.

also, a recent thread which I'll have to have a look for again showed pics of mimosa trees on farms which had been harvested.. they showed the whole trees stripped from top to bottom.. branch, stem, trunk ... essentially everything but the rootbark. this would make sense to me as is the case with alkaloid containing acacias... though I do also remember reading analysis of other parts of the plant containing very little. the member who posted the thread seems to think that the mimosa people buy is falsely sold as rootbark, and the photographic evidence provided was intriguing

The pipes look around 4-5" . The thread is worth checking out but you will need to register to view. The OP reported a massive difference between the pipe grown and freely grown plants.

how is it then that people are able to extract and get something out of it ,

i imported 3 years back so i dont know whats happening now ,

however if this is true , i see this a wake up call to entheogen lovers to grow there own , grow your own and get it real then

I didn't say the rootbark doesn't have DMT, I said that according to this member and the photos they posted, the bark from other areas of the tree is more commonly used commercially .. they say this is because it is less labor intensive ... and if this is true then it means the rootbark needn't be used as the other bark is still great yield. according to their post (and a fairly blurry picture provided), the rootbark has much higher concentrations than the other areas of the tree and can readily drop a dmt rich resin when squeezed (they say its way over a 2% yield), though it is much more difficult to harvest, so the other areas are used... this is the first I've heard of it, though it is definitely interesting and worth looking into

here is the link with the photos:

I have spoken with people who have tried using the stem bark with basically no luck..the yield was so low you would have to stip the whole tree for maybe a few doses. That is what was told anyway. There is a report of active leaves though.

yeah thats what I'd heard.. and the analysis endlessness posted up showed the same.. though its interesting to see whole trees being stripped I'd like to know whats going on there

^mimosa tenuflora/hostilis stem bark is used in mass in the skin care industry. Far far more mimosa trees are used for this purpse than are used for rootbark extractions etc. It is likely that this is what is going on.
