[Clover] loves plant biology, and tends a small garden while she is at home during breaks from college. She says that her family is notoriously unreliable when it comes to caring for plants, so she decided to construct a greenhouse to ensure that her garden will still be around the next time she comes home.
With her raised bed garden built and her seeds planted, she started work on the greenhouse itself, which was constructed using PVC pipe and clear plastic sheeting. Satisfied with how the structure came out, she focused on the greenhouse’s watering system and moisture sensors. The watering system uses solenoids that are connected to a pair of Arduino regulated relays. The Arduino uses moisture sensors constructed from nails, triggering the water flow when things get too dry.
The controller along with its LCD status panel was mounted inside a bird house to protect it from the elements while keeping in line with the house’s decor. [Clover] seems pretty happy with the build, but we suspect she will be adding some temperature and regulation at some point, to facilitate longer growing cycles.
