How to Make an Aquatic Plant Protector

Greenhouse Fish

Recently, our fish had grown so big that they began eating all of our aquatic plants in our water tanks! Rather than watch our plants dwindle to nothing, we got creative. Innovation is always happening here at Growing Spaces and we have so many brilliant members contributing. With some lovely input and guidance from Claudia Stover we designed what Udgar coined the “APP” or “Aquatic Plant Protector”.

Here are instructions on how to build the Aquatic Plant Protector:

Materials

    • 14 ft. of “backer rod”
    • 5 ft. 6in. x 4 ft. of fine mesh netting
    • Approx. 30 ft. of twine
    • 3-5 small stones

This will make a ring approximately 4ft. 6in. by 3ft. You can simply increase the materials to increase the size of your APP.

  1. Purchase “backer rod”, fine mesh netting and twine (if you don’t have any on hand) from the local hardware store.
  2. Fashion the backer rod into a ring by tying the two ends together with twine. This is the visible floating ring you see in the photo above.
  3. Sew on a very shallow net of fine meshed fabric to the ring using your twine.
  4. Trim any excess net from around the outside edges.
  5. Put 3-5 small stones inside the net to keep the net partially submerged
  6. Transfer all the plants to inside the ring.
  7. As the plants overcrowd the APP you can either:
    1. Put them into the surrounding water to recolonize that surface.
    2. Take the plants out of the tank and mix them into your garden soil.

The entire APP system costs an inexpensive $10-15

I worked at Growing Spaces from 2015 to 2023 and returned in 2025. I’m here to guide you through purchasing a Growing Dome® greenhouse—from planning and site selection to choosing the right accessories for your climate. My goal is to help you create a thriving space for plants (and people!). I also manage the Growing Dome Advisor team and help with technical questions, installation documents, and day-to-day operations. I love empowering people to grow fresh, nutrient-dense food and watching a Growing Dome transform empty land into a personal sanctuary. I enjoy collaborating with our team to solve challenges and make it easy for anyone to buy a Growing Dome. I graduated from Western Colorado University in 2013 with a B.A. in Environmental Studies. In my free time, I enjoy hiking with my wife and our two big dogs, skiing, backpacking, and exploring the outdoors with my camera.
