My bad. Forgot some of you live far across the pond and the whole Fahrenheit vs Celcius thing.... So all temps are in Fahrenheit !!!
To properly decarb ganja do the following.
1) preheat your oven to 240*F
2) take 3.5 grams of dank nugs and roughly chop it up
3) put the roughly chopped ganja in a foil packet, think envelope made of foil.
4) put the package in the 240*F preheated oven for 30 to 40 minutes and the remove it.
5)) let it cool to room temp before opening it up.
6) it's ready to use!
What does properly decarboxilated / activated ganja look like?
It's far darker, almost but not quite burned. It's smells funky funky funky and your house will stink for an hour or so after its done. It's completely dried out and sticky.
How do I dose it?
A quarter of a gram per person is a great place to start. You can always eat more right? Once you know how it's going to effect you then and only then should you increase the size of the dose. If you don't you can suffer some pretty horrific effects. My wife was power stoned for eight hours and wasn't right for several days after. She is a novice and uses drugs infrequently at most if at all.
What's it like? How does it feel?
To be honest, it feels fucking heavy. Like more stoned then you could ever get then just smoking it. It will pound you into a thermo-nuclear orbital bombardment couch lock if your not careful and munch a few of them in one sitting. I have been high for two days before with some highly concentrated oil. So go easy withe edibles or you'll pay some pretty horrible effects. Keep the dose low and you'll enjoy it all.
My edibles suck or didn't work, what the fuck?
There is a simple answer, you didn't decarb it properly. It could be to hot or to cool in the oven or you didn't decarb (cook it) long enough or you went to long in the oven. Regardless it comes down to the decarb process. Do that correctly and your set with some potent edibles.
Can I increase the potency because my ganja isn't so good?
Yes you can! Lecithin is something you can try and it doesn't take much. Two table spoons per eighth of ganja (3.5 grams to be exact). Liquid lecithin is about twice as potent as granulated so I have found out. I used lecithin in all of my edibles and lecithin from sunflower seemed to be the best when in liquid form. It doesn't take much, seriously. It has diminishing return and is an emulsifier so it also helps bind water and fat (oils) when mixed and cooked.
So what if I want pot brownies quick and dirty?
1) decarb an eighth (3.5 grams) or a quarter (7 grams) of good top shelf ganja.
2) grind the decarbed ganja fine between two spoons as you add it to a boxed brownie recipe.
3) cook the brownies per the directions.
4) cut them into 12 even brownies for consistent potency.
5) eat one and get fucked up in an hour and a half or so for full on effects.
Hope that clears it up. It isn't rocket science and while there are a bunch of other ways to make it all happen, I think this is the easiest.
