I've been reading up on diy biochar and wondered if this is the perfect answer for utilizing my humongus pile of weeds or do I need more woody material?
Do you have a link? Sounds interesting.
There are lots of youtube vids as well.

I thought you needed wood to make charcoal for bio char.
If you have a huge pile of weeds I would simply compost them. I never seem to have enough compost. I have several daleks and keep filling them, and when I return they are less than half full so I fill them again and again. If I end up next spring with them more than half full I will be pleased.
Also things like sweet corn, rhubarb, courgettes, squashes and pumpkins love a good pile of weeds as a mulch.
I got 5 bins of good compost and 1 large pile plus 2 bins of weedy compost. I use the weedy compost in homemade grow bags but I am overwhelmed with the weedy stuff. If i put it back in the soil I'll end up with even weeds. I just don't know what to do with it.
