Frequently Asked Questions

 

How does it work?

  • Clean clay pebbles provide an attractive base

  • Upper roots take in oxygen

  • Bursting air bubbles keep roots damp and air humid

  • Lower roots absorb water and nutrients

  • Air bubbles oxygenate water and hinder bacterial growth

Soil-free

Soil

  • Soil attracts pests, such as fungus gnats

  • Over-watered soil prevents oxygen intake

  • Under-watered soil is difficult to re-hydrate

  • Over or under-watered plants cannot absorb nutrients efficiently

  • Dark, stagnant soil is ideal for bacterial growth

Seeds

Sprout seeds on damp paper towel and then plant sprout in clay pebbles.

Cuttings

Root cuttings in water and then plant in clay pebbles.

Soil-grown

Gently wash all soil from roots and plant in clay pebbles.

Bulbs

Plant bulbs pointy side up in clay pebbles.

What types of plants can I grow?

The short answer: almost all of them.

We have not come across any plants that did not adapt well. Our happy hydroponic plants include:

  • carnivorous plants

  • orchids

  • dwarf/mini veggies

  • flowers such as sunflowers and tulips

  • cacti and succulents

  • leafy houseplants of all kinds

Always keep the size of the pot in mind and choose your plants appropriately.

How do I maintain it?

Check the water level every two weeks and change the water every month. That's it, easy peasy.

 

Do I need to feed my plants?

Some plants need little or no food (such as cat grass and many succulents), and others require regular feeding (such as sunflowers and tomatoes). Most houseplants fall in between.

 

If in doubt, follow the directions on your plant food bottle and feed your plant with every water change.

Always use a plant food that indicates that it is appropriate for hydroponic use.

 

What about lighting?

Always follow the lighting recommendations on the tag for your specific plant.

If you don't have much natural light available, there are many LED lighting options available that use very little electricity. Single bulbs are very inexpensive and fit into any standard lamp fixture. 

 

Artificial lighting can allow you to grow full sun outdoor plants indoors, such as sunflowers and tomatoes.
