XL (Extra-large hydroponic planter with air pump port)

Summary

XL is a 12.5cm square-shaped hydroponic planter with a water depth of 7.5cm. It can accommodate an air pump with standard 6mm air tubing. It is designed for growing herbs, strawberries, leafy vegetables, and other handy-sized plants. You need to water it once a week or less when you grow "planter-size" plants (12.5cm square). Plants grow faster when oxygen is supplied via the pump (See the third image).

As the plant holders are compatible with S (small), M (medium), and L (large) planter, you can use S for nursery plants and replant them in M, L, or XL after they grow up. You can also use Plantarium (lighting system) to provide compact yet effective lighting.

• S (Small hydroponic planter)
• M (Medium-sized hydroponic planter)
• L (Large hydroponic planter compatible with depth sensor)
• Plantarium (Flexible plant lighting system)

XL could connect with the Raspberry Pi-based IoT kit (See the last image). The kit can measure water depth, CO2, light intensity, temperature, humidity, take photos, upload measured values and photos to Google Cloud (Google Sheets and Google Photos), and send summary and alert mails. You can learn how to use it in detail in my Udemy course.

How to use

Growing mediums

• You can use dishwashing sponges cut into 2.5 cm squares (refer to the sixth and seventh images).

Growing seeds / nursery plants

• If you would grow plants from its seeds, be sure to prevent drying by covering seeds with toilet paper until the roots have grown out of the sponge.
• You can use a small bowl to grow from seeds, as you can observe well the water level and the roots. Refer to the eighth image.
• When you buy nursery plants instead of seeds, cut the sponge in the middle, wrap the plants, and set the sponge in the planter. Refer to the eleventh image.

A depth sensor

• VL6180 (depth sensor) can be attached to depth_sensor_attachment with M2 screws (8mm length) and M2 nuts. For further information, refer to my Udemy course
• When you don't use a depth sensor, instead of a "depth_sensor_attachment", use a "cap".

Food-safety standards

• If you care about food-safety standards, you can apply a coating material that adapt to food-safety standards.

Print settings

• Adhesion assistants: brim for "tank" and “floor”
• Infill: 20％
• Filament Material: PLA (The clearances are adjusted for PLA.)
