Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the column, and also holds set up a mesh screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An Greenhouse Gear Reducer automated watering system delivers a dilute nutrient answer to each column. The watering program is programmed to include small amounts of nutrient answer at the substrate surface 20 times each day. This high frequency helps to keep the tops of the columns moist and ensures delivery of nutrients throughout the column.

We’ve developed a columnar plant lifestyle system that supports healthy plant growth while also enabling complete separation of the roots from the growth substrate.

Standard potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support an appropriate balance of drinking water and oxygen while also offering 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 device and further increases the reliability of the machine. Because of this, the drive device can be used in every position. We has been tested under severe conditions with high operating cycle 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom mounting and part mounting, which facilitates set up and reduces the labor strength of the installation workers.
reducer furthermore to light weight, high strength aluminum alloy shell, the inner usage of a three-stage helical equipment transmission, thin oil lubrication. Increased transmission efficiency and service life. Its limit device has two types of collision prevent and springtime sheet for clients to choose. The limit adjustment is easy, and the positioning accuracy is high (especially the spring type). Can be adjusted within the number of 1~75 rpm to control the stop between the negative and positive of the motor. There is no double insurance switch to ensure safe operation.

1. The cabinet structure is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device gets the best wiring method, through three micro-switches, each of which features 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 could be arranged within a small area, like a gas-exchange chamber, therefore maximizing the number of treatments and replications in a given space.
