The disadvantages

Besides the above advantages, the round obelisk for clean vegetables growing at home also has some disadvantages that you should know and consider before investing in a round obelisk for vegetable growing. 

  • Pay attention to the location of the round obelisk: The tower must be placed in a place with 20-25% more sunlight than other types of vegetable growing on a surface. This is the reverse side of vertical space expanding. So please remember that your vegetable tower needs at least 4 hours of sunlight a day!

  • Limited watering: Because of the small holes' design, which prevents sunlight from harming microorganisms and limits water loss for the roots, as a result, you will feel uncomfortable and entangled every time you water the plants.
  •  How to take care of the round obelisk: You must always maintain the soil in a moist state, even if you do not plant anything, because the vegetable tower uses organic methods to grow vegetables. The worms and other soil microorganisms will die if the soil is left fallow or dry, draining it of nutrients. It will take a lot of work and time to restore the tower because you have to remove it to mix new soil.
  •  Initial investment costs: Despite being aware of the benefits of the round obelisk for clean vegetables growing at home, not everyone is brave enough to invest in their vegetable garden due to fear of failure.

Instructions on how to make a round obelisk for vegetables growing

You can create your own round obelisk for vegetables growing as the following simple, economical materials:

Round obelisk from plastic bottles

  • Step 1: Wash empty plastic bottles and let them dry.
  •  Step 2: Cut the bottle in half and punch the drainage holes.
  •  Step 3: Fix the small plastic bottles to the large plastic bottles with string or a glue gun.
  •  Step 4: Pour in soil and sow vegetable seeds as usual.

Round obelisk from a plastic drum

  • Step 1: Choose a plastic drum with a capacity of 200 liters or more; clean the drum; then drill and cut to create a vegetable growing tower. With a 220-liter plastic drum, you can cut about 54 holes for growing vegetables.

Round obelisk from plastic pipes

If a drum cannot be found, you might be able to build the tower out of plastic pipe. Making a tower out of plastic pipes is quite similar to that done using drums; however, due to the relatively small area of plastic pipes, the efficiency is lower. The plastic pipe needs to be washed first. The pipe body will then need to have a set of staggered holes punched into it so that enough light can reach the plants. Finally, shape the planting hole and get the soil ready for growing vegetables.

Pyramid-shaped, round obelisk for vegetables growing

Each floor of the vegetable tower will receive an adequate amount of sunlight due to its top and bottom pyramid designs, and you can water it without worrying about tangling. Use a wooden frame or a storage shelf to create a frame, then attach the washed and cut plastic bottles to the pyramid-shaped frame. With just a few simple steps, you can make a clean vegetable tower at home.
