I am attempting to grow Tatsoi and Lettuce outdoor during winter. For a bubbler, I used a solar powered water pump, a very neat little system that works great when the sun is out. Due to temperature, the plants did not perform as well as they should have. Regardless, the experiment was fun and a good learning experience.
