Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to the bottom of the pipe stabilizes the column, and in addition holds in place a mesh screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An automated watering system delivers a dilute nutrient answer to each column. The watering program is programmed to add small amounts of nutrient alternative at the substrate surface 20 times per day. This high frequency helps to keep the tops of the columns moist and ensures delivery of nutrition throughout the column.

We have developed a columnar plant culture system that supports healthy plant development while also enabling complete separation of the roots from the development substrate.

Regular potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper balance of water and oxygen while also providing exchange areas for plant nutrition. Separation of plant roots from the potting substrate, however, is impossible.

An oil expansion chamber controls the pressure in the drive unit and further increases the reliability of the unit. As a result, the drive unit can be used in every position. We has been examined under severe circumstances with high operating routine and excellent results have been achieved.
The new type of greenhouse reducer is a window in the greenhouse, universal screen reducer, it uses aluminum die-cast housing, beautiful appearance, light-weight (about 20 kg), good heat dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom mounting and part mounting, which facilitates installation and reduces the labor strength of the installation employees.
reducer furthermore to light weight, high strength aluminum alloy shell, the internal use of a three-stage helical gear transmission, thin essential oil lubrication. Improved transmission performance and service existence. Its limit device has two types of collision prevent and spring sheet for customers to choose. The limit adjustment is hassle-free, and the positioning accuracy is high (specifically the spring type). Can be adjusted within the range of 1~75 rpm to control the stop between the positive and negative of the motor. There is no double insurance change to ensure safe operation.

1. The cabinet structure is solid, reasonable, dependable performance, simple procedure and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each which functions as a brake, emergency brake, and phase mistake protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking on less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the number of remedies and replications in a given space.
