Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to the bottom of the pipe stabilizes the 
column, and also holds in place a mesh screen. The mesh supports the Turface substrate while also permitting water to drain by Greenhouse Gear Reducer gravity. An automated watering system provides a dilute nutrient alternative to each column. The watering program is programmed to add smaller amounts of nutrient option at the substrate surface area 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’ve developed a columnar plant lifestyle system that facilitates healthy plant growth while also enabling complete separation of the roots from the growth substrate.
Regular potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance of drinking water and oxygen while also offering exchange areas for plant nutrients. 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. Because of this, the drive device can be used in every position. We has been examined under severe conditions with high operating cycle and positive 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 level mounting and side mounting, which facilitates set up and decreases the labor intensity 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. Improved transmission effectiveness and service existence. Its limit device has two types of collision prevent and spring sheet for customers to select. The limit adjustment is hassle-free, and the positioning accuracy is high (especially the spring type). Could be adjusted within the number of 1~75 rpm to control the stop between the negative and positive of the motor. There is absolutely no double insurance switch to make sure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device gets the best wiring technique, through three micro-switches, each of which functions as a brake, emergency brake, and phase mistake protection
Columnar containers are preferable to pots because they can support deep root growth while taking on much less bench space. Many columns could be arranged within a small area, such as a gas-exchange chamber, therefore maximizing the amount of remedies and replications in a given space.
