I just got the stuff from my hydro store but you can get it online too.
I used dried herb but it works wet too. I went with sugar leaves and popcorn but you can use any part of the plant.
Chop it with scissors over a kitchen sieve and try to push as much of the dust through into another bowl which I bag for later.
Place the course material into a glass bowl, cover with alcohol.
I put it into a curing jar this time and shake it frequently or you can just cover the bowl with cling wrap and let it sit for 12 hours.
Strain mixture through cheesecloth, silk or an old "Thomas the Tank Engine" swim shirt into a lasagna dish or similar flat glass or ceramic dish.
I ran the mixture through a few times just to get all the crap out. You have to squeeze all of the liquid out you possibly can. I suggest using two hands, sticking your tongue out the side of your mouth and an angry face which will help considerably if you have little arms
.
Cover 3/4 of the dish with cling wrap and place in the sun for three to 5 hours. I use my 400w MH for this process with much speedier results.
The resulting sun bleaching activates the chlorophyll and turns it brown and makes it smell nice and sweet.
Preheat your >>electric<< (not gas) oven to 90°C remove plastic and place dish in with the oven door, windows, front door etc open and the rangehood and exhaust fan on.
You could do it outside but it would take forever and risk of contamination.
Cook until its the consistency of honey.
Add back a small quantity of Duct that was collected at the start.
Scrape mixture into a blob on a 30cm/ 30cm sheet of grease proof paper.
Let it slowly dry for roughly 12 hours. You can speed it up further by regularly "folding" mixture like a samurai sword and placing mixture in a warm surface such as a laptop transformer or X-box.
There is no need to add anything else but if mixture stays wet more dried mixture can be added.
Once mixture has lost it alcohol smell it is ready to smoke. I tested it in small amounts by setting on fire. If there is still alcohol present it will crackle when burned.
Roll onto a snake and wrap tightly in original grease proof paper and compress under roughly 1-3 kg for a few hours.
My old code word for this product was "Black lounge" because of its color and effect
