 Growing mushrooms hydroponically

There have been a number of posts about growing mushrooms hydroponically and they have all been dismissed as impossible or simply a ploy to raise the price of mushrooms. It has been pointed out that mushrooms can't be grown hydroponically because they are not plants or that they are technically grown hydroponically already because mediums such as WBS and BRF are not soil. I was just thinking about how hydroponically grown mushrooms could be achieved.
First of all mycelium will readily colonize nonnutritious substrates such as vermiculite until it's source of food is depleted. Also LCs are proof mycelium can grow in a liquid medium.
I propose this: take a small Tupperware container and fill it with moist vermiculite, mix in some colonized substrate and wait a few days for the mycelium to begin to colonize the vermiculite. Then flood the container with water mixed with a small amount of honey, malt/dextrose, corn syrup etc. Drain the substrate after a minute or two then let the mycellium colonize again. Repeat as necessary until the substrate is completely colonized then fruit.
The largest problem is sugar water is the perfect environment for bacteria so this entire thing would have to be self contained perhaps a small sealed Tupperware container with the mycelium/substrate with two holes for hoses in and out. That could be inside another container which holds the sugar/water reservoir and pump.
Obviously this would be a difficult undertaking and would only be for novelty but it would be cool. What do you think?

Being a living organism, I would imagine in order to flourish and fruit it would require more than just sugar and water. What about starches, carbs,protiens, vitamins, minerals etc. and in what proportions?

If this were possible wouldn't mushrooms grow in ponds?

A quick search will deliver dozens of hits where this has all been tried and experimented on, including an offer of a free microscope. Read up on those threads first so you're not starting from scratch.

Trouble is that plants have roots and fungi do not. Plant roots are designed to soak up water so you can keep them in a solution; if you submerged the whole plant it would die unless it had special adaptations.
Yes, you will see clouds of mycelium in a liquid culture, but the osmotic stress will probably hinder the fungus from maturing to the point where it produces mushrooms.

So RR does that offer still stand  ?
I want a microscope pretty bad, and I need something new to experiment with. Could it be a ten gram oyster mushroom or is that cheating?

I've had mushrooms grow on a pair of old jeans and they can grow off burlap.

There are a few kinds of mushrooms that grow underwater. I've heard of at least one. I believe they work similar to underwater plants, using dissolved oxygen.
@ the OP - It would contaminate. Sugar water would attract large amounts of bacteria and mold. Also, mushrooms need protein and fats as well as carbs. Providing sugar would only give them carbs, and they would not develop properly.
-Mushrooms need proteins, as they are the basic building block of the organism.
-They need lipids (fats) to compose their cell membranes.
-They only use carbs for energy.

Bear in mind that plants are autotrophs and fungi are heterotrophs, ergo: plants just need water and light and air to survive (dirt is merely a convenient place to grow) whereas fungi have to eat things, albeit differently than we do. So you will still need to feed them liquified nutrients somehow, and that is gonna be nasty, like the black liquid 'food' that the machines pumped into the humans in the Matrix.

The largest problem you would likely face - after perfecting liquid fungi food - would be contamination of the food. It isn't very likely to be efficient.

So far, nobody has ever fruited mushrooms on pure liquid culture. Vermiculite is not 'inert', so you could possibly dump sugar water on it and get a few fruits, but it wouldn't be hydro.
The rules for getting the microscope have been posted a dozen times or more. Check it out. Oh, and I won't ship it out until your result has been duplicated, which is necessary to prevent cheating. . .unfortunately.

Rodger Rabbit that isn't unfortunate. If I somehow did magically find a way to grow fungi hydroponically I think it would be worthless if it couldn't be repeated.
Well I'm going to do some research on some enzymes and such and I'm sure I will find this is impossible. But once again if I do find a way I will have a huge neener neener thread about it.

I always liked the idea of a series of wick based tubes that run through a a tub of colonized substrate, grain for instance.
The wick tubes would very slowly deliver mushroom nutrients then the mycelium would grow onto the wick tube and then draw nutrients at whatever rate it needs.
This would prevent over-nutrifying and making the whole thing prone to contamination. It would also allow the mycelium to draw as much extra moisture & nutrients as it needs.
Ideally the setup would deliver nutrients but even if it effectively delivers just water directly into the substrate it might have potential to increase yields.

So.. free microscope if we manage to fruit a liquid culture with no solid food whatsoever? I can think of a method to grow mushrooms in water. I'll try it.

It has to be more than that. I forget the rules but plenty of people have old LCs with mushrooms in them. There was some sort of weight requirement.

Don't confuse dunking with hydroponics. Mushrooms don't grow hydroponically. To prove that, I will send a free microscope to the first person who can grow a ten gram or larger fruit on a rockwell cube with nothing but liquid solution, and show the rest of us how to duplicate the experiment.
RR
Does it have to be a rockwell cube... can we use something else non-organic? And is this offer still valid Roger?

It's complicated. Sometimes people will say whatever they can to raise the price of things. I was once told by my girlfriend's buddy who showed me some dried cubensis (that had blued a bit) that she paid $90 for what seemed to be about 2 grams of semi-dried product. She tried to tell me that these mushrooms were of a "breed" that not alot of people know. The worse was when she told me they were expensive because they were natural and organic......having not been grown in someone's closet (she said it with such disdain) but rather picked from nature.
I would wager, though, that most people are just misinformed. Growing cubensis does not require an advanced understanding of their biological processes.
As far as being impossible, it is impossible to grow fungi hydroponically, but they do grow in liquid culture. The two are often confused in this type of thread. They are not the same.

You're right, but a liquid culture is not automatically, if ever, hydroponic.
Here's the confusing thing about these types of threads:
Are we talking about taking cubensis from mycelia to fruit in a liquid medium or trying to break the rules of nature and grow a heterotroph in an environment designed for autotrophs?
If you want to grow cubensis in a completely liquid culture, that's probably possible, but it's not hydroponic and, as you point out, it wouldn't provide any benefit beyond what's possible with standard techniques. Here's a thread that goes through it pretty thoroughly:

The rules to get the microscope were to grow mushrooms on a non-organic and non-mineral base, with only chemical nutrients(not grain based), much like practiced by pot growers.
The offer was in response to people who didn't know the difference between fungi and plants, who somehow thought if you knew the exact chemicals required by mushrooms, you could supply those in solution and have hydroponic shrooms. However, fungi doesn't choose to work that way.
