II expandable air pruning pot has revolutionized horticulture containers. The design has been refined for decades. The air pruning pot walls are manufactured of thermoformed HDPE and will last for multiple seasons. The unusual air pruning pot design creates better plant growth in multiple ways. Healthy bacteria are able to release more nutrients to the plant due to the well-drained and aerated grow media, and the root system structure of the plant is dramatically improved from the increased airflow pruning the root tips. This air pruning process begins with the tap root. As soon as the tip is dehydrated from contact with the air, the subsequent pruning that takes place stimulates lateral root growth. At that point, every new root is guided to an air hole along the air pot wall where it, too, will be air pruned thus further stimulating additional lateral root branching back at the stem. This repeated process causes the tree to develop a massive amount of outward-pointing fibrous roots. More lateral roots enable the plant to absorb more water and nutrients, stimulating faster plant growth. These root-building air pots produce a dense mass of fibrous roots with NO circling. When the tree is eventually planted into the landscape it will be healthy enough to instantly establish itself into the soil. Roots power the plant. Their importance cannot be ignored.
Benefits of RootBuilder® II Expandable Air Pruning System for Tree Nurseries
Exceptional growth rate using the RootBuilder®
II Expandable Container System in tree nurseries makes it possible to shorten the production time by up to one year. Compared to field-grown trees, growers may see an increase of 50% from the same area of land. Plastic nursery containers cause root deformity by way of root circling which clearly affects the trees’ growth rate. On average, a tree without root deformity grows faster (sometimes as much as 40% more) and increases the rate of growth as the trees mature. The benefits of growing in RootBuilder®
containers are not limited.
Time and money are spent hauling trees back and forth to the potting shed when it comes time to shift up in container size when using traditional smooth black plastic nursery pots. The Expandable RootBuilder® Air Pruning System eliminates those costs. You choose when and how much to increase the size of the container ON SITE in the field as your seedlings grow.
RootBuilder® II Expandable Air Pot Containers for Cannabis
Pick the right pot, and you’ll see your cannabis plant develop into a vigorous specimen, offering you as many buds as its genetics allows. Time, thought, and minor financial investment in selecting a high-quality growing container is more than worth it. RootBuilder&trade II air pot systems allow the roots of the cannabis plant to stretch out and search for oxygen without getting constricted – just like it would do if planted in the earth. When roots start to feel themselves getting close to their oxygen source, they harden at the tip – a process known as pruning. This allows them to stop growing while maintaining their health. Normally, especially with mother plants, cannabis growers must do this manually, which can be tedious at best and exhausting at worst. With the RootBuilder®
air pots, that all happens without extra effort on your part. There is virtually no risk of becoming rootbound. Additionally, storage of the RootBuilder®
II is extremely easy – remove the cable tie and you have a flatten panel easily stored.
RootBuilder® II Container System Offerings
II Air Pot System is available in three offerings:
1. Kit – easy to assemble pre-cut air pruning sidewall panels, base, and cable ties (5 sizes: 1 pint; 1 quart; 1-, 3- and 5-gallon)
2. Pre-Cut Air Pruning Panels – flat, pre-cut air pruning sidewall for larger air pruning pots (7 sizes: 15-, 20-, 30-, 40-, 55-, 70-, and 100-gallon)
3. Air Pruning Rolls – 96’ air pruning pot sidewall rolls for you to determine cut size (2 heights: 17” and 34”)
It is recommended to use a soilless mix for 1-gallon and larger containers. The following recommended recipe is based on a cubic yard of mix before adding fertilizer
