The 3Dponics Mini is a great introduction to hydroponics, especially for first-time gardeners and beginners. All you need is a couple empty plastic bottles and the 3D-printed Bottle Connector. No pump and no electricity required!

HOW IT WORKS
This hydroponics garden is super simple: it requires no power and very few materials. Although the watering has to be done manually, you only have to do it once every few days.

When you pour the nutrient solution into the plastic bottle, the solution slowly makes its way through the grow medium, plant roots and Bottle Connector and drains into the reservoir. You then unscrew the reservoir from the Bottle Connector and connect another empty plastic bottle in its place. Save the full plastic bottle for the next watering cycle!

Alternate like this for as long as your garden makes you happy!

WHAT YOU’LL NEED

Step 2: 3D Print the Parts.

If you’re using a MakerBot or Ultimaker, we recommend the following settings:

Medium quality
0.2 mm
10% fill
2 shells

Step 3: Assemble the Bottles.

Cut the bottom of the bottle you’re planning to use as a planter. Screw it onto the top end of the Bottle Connector. Screw a second bottle to the bottom end of the Bottle Connector; this will act as the reservoir. Place the assembly on a flat surface or hang it on your wall (making sure that the top of the system is still within reach).

Step 4: Add Your Plant.

Gently add the plant to the planter bottle and surround it with grow medium, taking care not to damage the plant roots.

Step 5: Prepare the Nutrient Solution.

Fill the third plastic bottle with nutrient solution and slowly pour it into the planter. The solution will gradually drain into the bottom bottle.

Step 6: Water Your Plant.

Carefully unscrew the full reservoir bottle from the bottle connector and replace it with the now-empty third plastic bottle. Place the full bottle aside until your next watering cycle.

NOTE: We recommend you water your plant every couple of days.
