Ash is mostly made up of the mineral content of whatever was burned.

I've always been interested in the difference between my cannabis ash and ash from flowers I don't like the quality of.
I have read online or in a book that the only things remaining in ashes (from wood) are K, calcium, magnesium, P and some micro's IIRC. All the rest gets combusted.
It's for this reason that woodashes are a very good source of K.
Anybody any other input? Preferable about Cannabis ash.

Dry it and a match. Best outdoors.
Easy, peasy, lemon squeezy.
I'm just kidding mate, it would be awesome to see those testresults.

I'm actually puting back some of the joints ashes into the compost pile, and was wondering as of late about others doing the same, so, it seems my message got across :-D

I don't have a clue with this stuff. Is it really as easy as just burning the dry plant matter? Do I need to do it in a low oxygen environment, like making bio char?Dry it and a match. Best outdoors.

Yes, it's that easy. The thread is literally about ash made from Cannabis (flowers, stems, leaves).
Ash as in the woodash amendments you can get in gardencenters or is in your ashtray.
It might on the other hand also be interesting to see how biochar and oxygen deprived burned material testresults correlates to regular ash made from Cannabis.

Alright. Does the ash change any over time? Like if I harvest in 2 or 3 weeks then let it dry a week then burn it down to ash, can I just keep that ash in a bucket till it's time to get it tested? Or should I wait till closer to testing to burn it?

In the combustion any organic compound is burned out, so no N in the final NPK. most wood ashes have 0-1-3, i dont know cannabis.
In biochar I think no nutrient is available directly from the biochar, biochar is bioaccumulator and soil improver, but has no nutritional value by itself. Why dont do some worm compost and supercharge biochar in the compost? my worms eat pot butts, cannabis ash, cannabis leaf branches and roots from harvest, kitchen vegetal crap, paper, etc

If you light a joint with a lighter traces of lighter fluid will be in the ash correct?

off topic but along the lines of trace elements...
A hydro chem grower once told me there was no way to grow organically due to chem trails skewing the notion of it being cleaner and purer. Said he grows indoors to keep that shit from raining down on his crop
always something eh?

I will look in my notes when I get home.
I have npk amounts from hemp ash.
Probably not ash of flowers, but it's ash of cannabis.
Been saving my weed ashes for over two years. Either gonna mix with compost, or use to make lye soap. Cannabis lye soap. Made from cannabis seed oil, and cannabis lye.
