Product Description

Size: 20-Gal | Color: Black

The Smart Pot® is a soft-sided aeration container that air root prunes your plants. Air root pruning is a key component to a healthy fibrous root ball. Unlike plastic containers, roots do not circle. Instead, air root pruning creates a more fibrous root structure with more root tips. More roots means quicker growth. No circling roots mean better growth.

From the Manufacturer

Smart Pots Patented Aeration Containers Grow Better, Healthier Plants!

About Smart Pots

Nurserymen and Master Gardeners alike have known for over thirty years that Smart Pots grow better plants because of the fabric used in their construction.

The tough, long lasting Smart Pot material has just the right amount of porosity to promote air root pruning, excellent drainage and allow excess heat to escape, producing superior plants. The patented soft-sided containers last for years, even in the harshest winters, and are excellent for growing the widest variety of container or potted plants.

A healthy, well-established root system is key to overall growth, and Smart Pots provide roots with an ideal environment, allowing them to thrive and develop to their full potential. Vegetables, flowers, herbs and fruits all do well in Smart Pots. Smart Pots are the horticulturist's first choice for container gardening!

Smart Pots are 100% made in the USA. All of our raw materials and manufacturing processes are sourced in the USA. Our fabric is totally inert and free of chemicals and BPA’s.

Air Pruning in Smart Pots

As roots grow in containers they eventually reach the container walls. In hard-sided containers, these roots, upon reaching the walls, start circling and continue to circle, seeking a friendlier environment. Upon examination, these root systems exhibit a few strong roots growing in circles with very little branching, often are bound or girdled upon themselves and, depending on the type of plant, can produce a strong tap root growing through the containers bottom.

These characteristics can hinder the plant's rate of growth and in some cases its chances of survival when transplanted. Roots grown in a Smart Pot come in contact with the fuzzy, fabric inner wall of the bag and penetrate or grow into the fabric. The bag's tough fabric prevents the root's continued longitudinal growth, in effect pruning it, causing the root to develop masses of lateral fibrous roots. Upon comparison, root systems that developed in a Smart Pot have a much greater mass or volume then those found in hard-sided containers.

Plants grown in Smart Pots have root balls that contain many more roots than found in a hard-sided container of similar size. The fibrous root systems produced in Smart Pots are more efficient and enable plants to maximize water and nutrient uptake in the limited surrounding soil mass.

Controlling Plant Temperature Using Smart Pot Containers

The Smart Pot’s black fabric quickly warms up early season soil, enabling plants to get off to a quicker start. Yet the same fabric, due to its porous nature, allows heat to escape from the container through evaporative cooling during the summer's hottest days.

Even in northern climates, root systems of container-grown plants can be damaged from too much heat. University studies have also shown a direct relationship between soil temperature and slow-release fertilizer activity. Cooler containers do not allow for premature fertilizer release.

Indoor Gardening

Gardening indoors can be as fun and rewarding as gardening outside. It can also be less of a headache! When you garden inside you bring everything to your plant: light, water, and food. Using a hydroponic system is one of the best methods to do this.

When you garden using hydroponics you control everything. Your system delivers everything your plant needs so all your plants have to do is grow. When you’re indoors you’re in charge.

The hydroponic industry for a long time has done a great job in providing the hydroponic hobbyist a nice selection of good quality lighting, nutrients, additives, pH testers and balancers. But it has had a limited selection of containers. This meant that the gardener was forced to place their plant in a system that provides the best light, the best food, and an environment for optimal performance. However the container they had available for use was limited.

Not anymore. The Smart Pot is the perfect complement to any hydroponic enthusiast’s system. The Smart Pot provides an environment for the root system to allow it to do what the lights and nutrients are asking it to do. Most other containers don’t do this. The fact is the Smart Pot is the best container for gardening in a hydroponic system. Here’s why:

The Smart Pot is made of a porous fabric which allows water to flow freely while keeping medium inside – no more clogged hoses.

The Smart Pot air prunes the roots which creates more roots through branching; more roots means more root tips and more opportunity for the plant to feed.

The Smart Pot stimulates beneficial bacteria because of the aeration – beneficials need oxygen.

The Smart Pot allows the plant to use all the space inside the container for root growth, thereby letting the plant grow bigger than traditional hydroponic containers allow.

The Smart Pot doesn’t allow roots to circle, making it the ideal container for a mother plant.

The Smart Pot releases heat, keeping the plant free from stress.

Give your plants what they want: room to grow, air to breathe, and an environment to thrive. Give your plants the Smart Pot!

I live in SoCal, and I've got 3 of them (2 2-gallon and 1 3-gallon) in use out back right now, and everything is growing well.

I plan to put several new fruit trees in 65-gallon Smart Pots this spring----Navel orange, fig and avocado.
Right now I am growing shallots, garlic and heirloom tomatoes in them.

So far, they are performing as well as claimed by the sellers.

If I learn anything new about them, good or bad, I will subsequently report on it in this space, in coming months.

But so far, so good.
===========Supplemental report (several months later) :

As time passes, I have become convinced that the bigger smart pot you use, the easier and better will be the results.
The 2 and 3 gallon sizes seem fine for spices or smaller plants,but need more frequent watering than the bigger containers.
It's early June now, and I have a dozen Smart Pots currently in use.

Once again, with fiber pots, bigger works better.
I love the 10, 15 and 20 & 30-gallon sizes.

I am starting to prefer at least 7-gallon and larger sizes best of all for this reason.

I've got tomatoes in 10-gallon smart pots and they are thriving, as are brussel sprouts, canteloupe and broccoli in 10 and 15-gallon pots.

I am even using a 15-gallon pot for a "potpourri" area with 4 or 5 different veggies planted in it,in different sections---Much easier
to set up than a raised bed, for sure. And it works just as well from everything I've seen so far over a few months.

As for perennials, I plan on putting some big, honking Artichoke plants in a 30-gallon, and a bunch of asparagus in
at least a 20, or larger. Also some rhubarb in a 15 or so.

Darn good product, IMO.

I purchased two of these to start out my vegetable garden instead of using the five gallon plastic bucket method everyone back east would set up in their backyards. My main reason for trying the smart pot is heat regulation, gardening can be a challenge in southern Arizona. The fact that the roots will air prune rather than get bound into a ball is just an added bonus. After two weeks my plants have more than doubled in size. Today I am ordering two more.

For anyone who is planning out what they need, the ten gallon bag will take a full bag of garden soil as well as an additional 3/4 bag of compost to fill for planting. I have a single cherry tomato in one planter, and a bell pepper in another, but could have put them both in one.

I recently found out about "air pots" from one of the employees at Annie's Annuals & Perennials. They deal in exotic and rare plants, so I took his advice to check into it, as a means to not only grow plants faster, but healthier. When I looked into it, I found two different types - the original plastic, with holes all around, and these cloth Smart Pots. The plastic pots being too expensive to just try out at the moment, the very practical Smart Pots caught my attention. Lightweight, simple to use, and economical. These would do the trick, so I ordered a variety of sizes for various gardening projects I have going.

Upon receiving the Smart Pots, I was pleasantly surprised. They are conveniently packaged flat (unlike any clay or plastic pots), and yet retain their originally intended shape upon opening. Very lightweight, which adds to the convenience, both in storage when not using, and in lifting them with plants inside. They hype proved to be true. These were the real deal.

The main aspect about the Smart Pot "air pots" is the aeration facet. Air is allowed inside from all over. As well, it is built to prevent plants from "root balling." Instead, the roots are "air trimmed" and forced to sprout the more effective smaller runner roots, which do a better job at collecting moisture and nutrients. One reviewer stated that one of his plants had almost "doubled in size" overnight. While I can attest that no plant of mine did exactly that, I CAN say with honesty that all the plants I put into the Smart Pots definitely grew faster and fuller, and appeared healthier.
