How To Make A Homemade System For An Urban Garden With Built-in Vermicompost

Today we publish a project by Juan David Guijó, who, seeing the need to have fresh vegetables without agro-toxins in his home, designed and manufactured this homemade system for urban cultivation with built-in vermicompost by hand. If you have the possibility, we recommend you have your own urban garden.

It took him several years to design something that really worked, but he finally managed to create and manufacture a garden system that occupies only 80 cm by 40 cm, where he can have a Californian worm compost so as not to dispose of vegetable waste.

He has dubbed this system the “worm farm”, a room where the worms begin their feeding process and from this result we obtain the liquid worm humus that will fertilize the automatic irrigation water. In the lower part are the seedbeds for the next sowing, closing the cycle to obtain our fresh vegetables throughout the year without agro-toxins.

How to do it.

The 4 ”tube is drilled every 15 cm in a staggered manner, the carbon filter is inserted at the bottom, the tube must be perforated at the bottom, leaving several small holes for water drainage.

The next container has perforations in its base, this is the one that will contain the worms and will be fixed in the upper part of the container that already has the tube. A hose is inserted from inside the 4 ”tube, this will be the one that carries the irrigation. Finally humus (soil) is introduced into the tube, we sow our seedlings to the taste of each one. The worms are placed in the container with a little soil and a portion of vegetable waste. An acrylic lid is made that does not pass sunlight, this lid has 3 holes, two of them you can plant tomato beans or any type of silver that needs height, in which a ¾ ”tube is placed with angeo with the so that the insects do not pass. Finally, the water pump is installed on the hose and programmed to do irrigation intervals during the day. We fill the pump container with water preferably without chlorine and with liquid worm humus.


  • 1 tube of ¾ “.
  • 2 Plastic containers 40 x 60 cm.
  • 2 meters of 4 ”PVC pipe.
  • 1 Submersible pump for drinking water.
  • 1 activated carbon filter.
  • 1 kilo of California worm.
  • 2 Mt Geotextile.
  • 2 Mt of duplex key N 2.
  • 1 electrical outlet.

Thanks to our friends, the worms, they turn our unprocessed vegetable waste into a fantastic natural fertilizer ( liquid humus ), which goes directly to the water container where it is bobed to water and fertilize the seedlings in our garden. Once they are ready to consume, they will be replaced by another seedling that we can germinate them in order to have constant production.
