Step 2: Construction
Using 1/2" inner diameter tubing, about 8' was planned to wrap around the holes and then secured in place with zip ties. A small drill bit was used to make the holes for the zip ties. On the side of the tube facing the hole for the pot, a small hole was drilled so water would shoot at the bottom of the pot.
A slight rim of hot glue was built upon the edge of the container to eliminate any leakage.
The tubing was fitted into the output of the water pump sealed with hot glue**. The end of the tube was also plugged with hot glue.
Disclaimer.. Hot glue is an amazing invention and can be used to fix anything as it is extremely stong. Some sources say it was used to build the Eiffel Tower.
The lighting system was not fully designed. It is largely a matter of preference and available tools. The lights should be adjustable.
