Fungi integration with underground greenhouse?

I have been doing a lot of research on making an earth-bermed greenhouse like on the wofati forum, I believe this question would pertain to fungi however. I have been researching getting started on growing mushrooms and the problem I have found is getting it to a point where I can consistently grow them year after year without buying more. and without harvesting bits and replanting them. Many of what I have researched requires a lab and equipment, and special rooms.

At the same time I have been researching using an earth integrated greenhouse to grow fruits and trees, what do you know about combining the two?

Any information, or tips you can give me on making a continual mushroom farm (or even just getting started) are very welcome :)

Joshua, I apologize for taking so long to get to this post.  I can’t remember why I didn’t respond when it first appeared months ago.

First, let say that I love this idea.  Also I am an avid fan—some would say fanatical—of growing mushrooms directly adjacent to garden crops.  Personally I use Wine Caps, but you might also consider oyster mushrooms as well.  Either will ravenously obliterate the wood and leave behind wonderful garden bedding.

It is early in the morning and I have not had my coffee yet but I wholeheartedly endorse your plan.  I know you have questions, please fire away with them and I will try to answer them when the cobwebs clear.

BTW, I only grow in homemade mushroom compost and the results are staggering!  I can’t think of a better growth medium than mushroom compost.

I had been looking at building an earth berm greenhouse and burying mushroom vaults in the back wall and making that part of the earth battery air circulation system.

Let me know what your thoughts are. I live in a place where its really hot sometimes, and really cold at other times, and it seems like this type of greenhouse can really add to growing yields all around, mushrooms need certain temperatures, so giving them a place like this might help a lot. Tell me about how you use your mushroom compost. Do you use existing compost to continuously propagate or do you need to keep adding more spawn?

Joshua,

So I have gotten pretty good at starting from pre-packaged spawn.  Using my own is a touch more difficult.  I really expected to simply add more chips on top of the old and watch the fungi grow.  But as it turns out, I apparently needs fresh spawn right from the edge of where the old spawn is invading new materials.  

I have used my own chips to spread spawn.  I have some comfrey that has some nice, thick wood chips at their base.  Last year I added some nicely infected spawn chips to the comfrey chips, buried under even more chips and this spring I actually had a few wine cap mushrooms pop up.  It was kinda gratifying to know that those shrooms were free, I bought nothing to grow them.

If you are interested in wine caps, I think you will want a soil interface and there are ways of doing just that.  If you want to try oyster mushrooms, they should do just fine we’ll up in the air (and they will obliterate wood quickly!).  Either way can be a winner.

I plan on growing some asparagus on chips decomposed with oyster mushrooms, simply to see how oyster mushrooms work.

Joshua,

I guess I should have also stated the response to the first part of your question.  I plant in about 12” of wood chips which then get broken down to mushroom compost.  By now, I basically grow exclusively in mushroom compost that I make myself.  

The compost with live fungi colonies is incredibly fertile.  I add in no chemical fertility and my tomatoes grow tall, lush and green and they yield up lots of tomatoes.

I am convinced of living mushroom compost as a growing medium.

how many crops can be harvested from logs in above photo before you need new logs to drill and plug. do logs last multiple years ?my limited experience is with watching turkey tails grow like crazy on ash trees killed by emerald borers but they only produce one season and then the rotted logs would grow no more turkey tails
