Smart Soil Separator

Smartsoilsep_1The Smart Soil Separator™ is designed to extend plant life by providing a permanent airspace to the plant’s root system. The flexible design of the Smart Soil Separator allows it to function in a variety of containers where the bottom measurement of the pot falls between 5” to 7” and there is one or more drain holes in the bottom.
It works equally well in both indoor and outdoor applications and is completely reusable. We have seen remarkable results in testing the Smart Soil Separator in one and two gallon growing containers with matching saucers.

Indoor Plants

oreganoGrowing plants indoors is easy and fun no matter what the season or the weather outside. House plants can thrive in an array of light conditions and room temperatures. Most prefer to dry somewhat between watering so make sure the pot you are using has drainage holes and some type of saucer to protect your furniture.
Adding the Smart Soil Separator will make a significant improvement in the health of your house plants.
In return, your healthy plants will be able to do their job of helping to clean the indoor air.

No More Rocks

container_aThe needs of plants and their root systems have often been ignored by pot designers.
To improve growing conditions “conventional wisdom” was applied and rocks were often added. It was thought the rocks would increase drainage. However, the use of rocks has the opposite effect.
Over time plant roots circle in the rocks, creating a swamp, reducing both air and water drainage and adding stress to the plant.

Plant Roots Are Starving for Air!

There is little understanding of the importance of air to potted plants. The only source of air to the roots are the open pore spaces in the potting mix.
Quality potting mixes will allow air to move down through the root system. Compacted or poor quality potting mix restricts the air to the roots resulting in poor root development and growth.
By using the Smart Soil Separator in all your potted plants, you are creating the much needed air space.

Here is what Experts Say

The lack of air at the root level reduces root respiration (one of the key ways a cell gains energy) resulting in the shutting down of photosynthesis in the leaves above.
Air at the root level allows roots to extract both water and nutrients more efficiently.
Air protects the roots from attacks by pathogens – infectious attacks by such things as a virus which can stunt the plant or actually cause its death.
“Plants can’t take up nutrients without air. Plants need air around their roots for nutrients to pass from the water in the soil to their roots.”
– Ed Smith, The Vegetable Gardener’s Bible

Circling Roots & How The Smart Soil Separator Can Help

circling_rootsThis is a condition that occurs in nearly all potted plants and is a constant problem in house plants that tend to spend their entire life in the same pot. They are large and easy to spot when a plant is removed from its container.
“Standard pots encourage the development of roots to grow around the container in a constricted pattern,”
state gardening experts at the University of Washington.
“Plants with circling roots have difficulty getting enough water and nutrients, shortening the plant’s life,” according to Oregon State University.
Gardening How To magazine recommends checking house plants for circling roots and “perform some root pruning to help plants survive.”

Pruning Circling Roots


Researchers at Washington State University have found that, “Circling roots are ‘burned’ or pruned when exposed to AIR.” The permanent airspace created by the Smart Soil Separator prevents the growth of circling roots in houseplants.

Highly Branched Roots

“When exposed to AIR, the plant will constantly produce new and highly branched roots,” Washington State University emphasized. “These highly branched root structures allow a plant to more efficiently uptake water and nutrients while increasing the growth and overall plant health,” University of Washington added.

Add A Smart Soil Separator

  • Give new life to any indoor plant
  • No More Rocks – Perfect Drainage
  • Adjustable for smaller pots
  • Perfect for any house plant, new plant or an already potted plant

Choosing a pot for outdoors

For your Patio, Deck, Porch or Balcony!
The Smart Soil Separator is designed to fit pots with bottom measurements between 5″ and 7″
The volume of the pot, however, may change depending on the side angle.plant_b

There are no hard and fast rules for which plants belong outdoors and
which belong indoors. Some plants begin indoors and get moved outdoors.
Grow Vegetables , Herbs, Flowers, Grasses
In recent years , as container gardening has rapidly increased,
growers have developed compact and dwarf varieties which do well in small pots.
Outdoor Plants as well as Indoor Plants need AIR at the root level:

  • AIR supports photosynthesis
  • AIR enables roots to extract more water and nutrients
  • AIR protects roots from pathogen attacks
  • AIR at the root level “burns off or prunes” circling roots
  • AIR produces highly branched roots
  • A permanent air space extends plants life.

Watering Pots Has Always Been A Challenge
Especially watering from the top


  • You never know how deep the water goes
  • Flushes nutrients downward and out

The Smart Soil Separator takes the guess work out of watering!

  • Reduces both water and fertilizer consumption
  • Sub-irrigation
  • Watering pots the way nature intended with the Smart Soil Separator


removable-chamberRemove the plug in the Smart Soil Separator – it easily punches out. This reveals the “wicking chamber.”

Position the Smart Soil Separator in the bottom of a pot. The pot should have one or more drain holes. The Smart Soil Separator adjusts to fit pots with a 5” to 7” bottom dimension.

Add quality potting soil, pressing some into the wicking chamber. Continue to add potting soil to your pot and plant.

Now add a saucer under the pot. The saucer acts as a water reservoir.pot-mark
NOTE: The airspace must be maintained. To accomplish this, manage the water level in the saucer so it does not exceed the top of the Smart Soil Separator in the pot which would, effectively remove the airspace.

The roots of the plant will pass through the airspace into the water.

The small amount of potting mix that is in the wicking chamber comes in contact with the water below. Some amount of moisture will move upward into the potting mix above. However, when plants are at their peak, the roots will actually pull up all the moisture they need.

“Since water is being taken up from the bottom, you can be sure the nutrients aren’t being washed away.”
-Ed Smith
The Smart Soil Separator
• Is not a “self-watering” system
Water must be added regularly
• Is not a “hydroponic” system
There are no pumps
• Using Sub-irrigation
The plants manage their own water supply.

The Smart Soil Separator has been successfully tested using a broad range of commercial potting mixes available at your local garden center.
However, because of its design and the permanent airspace it creates, the Smart Soil Separator will greatly add to your success when growing organic vegetables.
“An organic soil is alive and the creatures living in it need air to survive,” Ed Smith, author, “The Vegetable Gardener’s Bible.”
The Smart Soil Separator™ is designed to extend plant life by providing a permanent airspace to the plant’s root system.
