Natural pool in greenhouse

I don't see why it would be an issue, but would having a natural pool in an indoors situation pose any complications you can think of? Would you recommend that both the plant pool and the people pool both be indoors, or just one.

Hi Shawn,
I see no reason why this could not be made to work. In fact, I was planning to experiment with this idea. I have the poly tunnel tubes ready to go over my small pool to start experimenting. I plan to enclose the whole pool and see what happens.

hi,  did you ever do this, and any advice you could give?

I'm planning on more of a small pond in my greenhouse,but the principle is the same. Water has more than double the thermal mass capacity of stone or soil, so I'll be utilizing my body of water to regulate the temperature of the greenhouse.

I like this idea and researched videos for ideas. Here are a few that I found.

For what it's worth, it's been raining a lot here and the ground is very saturated.  For the first time in 30 years I almost stepped on a very large frog in my greenhouse.  Didn't even suspect he'd be there, but he hopped out of the way, luckily.  Now I notice that the container I use to catch drips through the ceiling has tadpoles in it, so it's difficult to use the water without a strainer.  I like tadpoles, I like frogs, but ....The water in the greenhouse requires my going up a big hill to turn on a tank, so there is stored water in the greenhouse to save time.   This isn't saving me time.

The other thing about these bigger frogs, they burrow into the soil in the winter, and if you don't know where they are you could step on them, or hit them with a trowel or shovel. There are also the smaller tree frogs hopping around as well, getting into things.  It's tricky to walk around with flats of transplants, tools, or even a string trimmer if you get weeds.

There are also mosquitos, which the frogs need to be present to take care of them, but some still make it.  Snakes come in after the frogs.  Birds get into my greenhouse, some of them would go after the fish.  Once word gets around, any number of critters will be trying to get in there.

How will you handle overflow?   Ground water has a way of finding such places in a rainy year.  Pond maintenance is time consuming.  It just makes it a busier place than it needs to be, and a greenhouse is not that big to begin with.  I want the greenhouse to be one place I don't have to worry about critters and extra chores.

Saving that space for a huge compost pile would add heat, and then it would be nearby to tend and use easily.
