There seem to be a lot of them on Amazon for $99-$199.

I give extra fruit to the people who come to the food giveaway at my church. The receivers of food all have nicer cars, clothes and phones than I do.

I highly recommend the baritone ukulele.  It doesn't have the same chords as the little ukes.  It is easy to learn like other ukuleles, but it is bigger and makes a bigger sound, like a small guitar.  You can look at guitar chord books, of which there are zillions, and figure out how to do the harder chords. The baritone uke uses the same chords as a guitar, but simpler, because there are only 4 strings instead of 6.  I play regularly with another guy in town. It's really fun.  I also play the piano and sing.  I tried to play the regular guitar, but the quick chord changes were pretty difficult. I didn't have an hour a day.  It always sounded kind of "off", but now it's great.

I remember going through Central California's valleys.  Forest Service people told me not to drink the tap water 35 years ago, because so much of the synthetic fertilizers and pesticides had permeated the water table. They all drank bottled water then.  Yes, there were tons of plastic bottles strewn about that county.

In many areas, you can't drink your well water, because they've been adding synthetic nitrogen fertilizers, that aren't mostly soaked up by the lack of organic material.  It goes into the water table.  This paper talks about a method to make biochar with iron to filter it out:

I agree. I would rather use wood to grow mushrooms if I can.  Not always possible, though.

Great info about the available range of use.  Maybe someone will invent something.

I think that probably a lot of people who use pressure cookers to make mushroom spawn will easily be able to make hydrochar as well.  For others, it may be more difficult.

I started reading an article that said that biochar produces more nitrous oxide in the atmosphere than hydrochar. Then I thought, What the  &%$#*! is hydrochar?

Apparently, it's a real thing.  It has some of the same uses as biochar.  As you guessed, it uses moist organic matter.  



I'm not pretending that I really understand hydrochar. There are so many smart people on these forums that I'm sure people will help us get what it's about.

Apparently, it's cooked like in a hot pot.  I will be interested to see how people make it and use it.  One advantage of hydrochar is that you don't have to dry the material.  Another is that it is more efficient in retaining the carbon as it's made.

There are real differences between biochar and hydrochar.
