This doesn't answer your question, but a few reasons I see this as not being a particularly successful option.

- Urine has a high salt content and this will build up in your soil in an indoor setting, making it eventually unsuitable for plant life.

- Even brightly lit rooms are many many times dimmer than the sun conditions that this plant likes. A lamp suspended within inches of the foliage is needed.

- Although these seem to be self-fertile, you may need to help out the pollination by shaking the plant since there isn't the normal range of wind and insects to assist.

Especially if you have a paved area, it could be grown in a pot outdoors as long as you harvest the seed pods before they start dropping seed. They spread via roots and seed, so being in a container in a spot where you can see any dropped seed will prevent spreading.

There are a lot of issues to address with this project. Firstly there's the simple fact that Chinese lanterns are not suited to growing indoors because they are temperate climate hardy perennials. They need more light than can be provided inside without lamps and they also need a period of winter dormancy. This brings us the the term 'indeterminate'. That means that a plant stem will keep growing and is not programmed to stop. The usual example is certain tomatoes. CL doesn't fulfil this criterion. They are perennials so the plant itself will continue to live but not individual stems. In winter it dies down. Now we come to the 'soil'. Garden soil is not suitable for container culture. And I'm hoping you meant you pee on it while it still outside and not indoors! Lastly you refer to 'harvesting a batch'. Do you mean gathering the orange seed pods for decoration? Because I'm sure you know the fruit are poisonous. The pods can last for years dried so do you need a large quantity? Is there any reason you can't grow them Ina container outdoors? That would overcome several of the problems with your idea.

and I pee in it occasionally).

==>>> nothing like a spare urinal, in the house ...

whats to lose ... just dont let it get out of the house ...

Thank for the input guys.

I don't really care about this dirt, I know about salt content in urine, I just want to see how long will it last, before I decide to throw it out. Also I been doing this for years with my english ivy and wandering jew in the same container and the plant growth how not been affect at all. But then again I have a false bottom in the container the salt could have been accumulating in there.

Also I pee in it indoor because I'm too lazy to walk across the house sometime ; D

I'm also harvesting the Pods and seeds for lulz. I really love the look of the pods, it make my place look nice.

It wasn't the salt content that was worrying me. It was the stink and the poor hygiene.
