Cherry shrimp in out side bucket?

[Niccobacci11]

I have an 18 gallon bucket outside with a uv sterilizer, power head, and a home made filter out of a pump, water bottle, and sponges. I live in San Diego and the temp gets up to about 85 but in the summer it gets to 100. I am using it to grow plants and I just want a little bit of a clean up crew. The water goes from about 50 and night to 85 plus during the day. My thinking is that they could survive the temperatures because it happens really slow and they have time to adjust. The tank gets full sun but will probably move it to getting about 6-7 hours of morning sun. Would they survive? Will they breed?

If you need more information just ask I don't know if I missed anything.
