Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to the bottom of the pipe stabilizes the column, and in addition holds set up a mesh display. The mesh supports the Turface substrate while also allowing water to drain by gravity. An automated watering system provides a dilute nutrient answer to each column. The watering program is programmed to add smaller amounts of nutrient answer at the substrate surface area 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 have developed a columnar plant lifestyle system that facilitates healthy plant growth while also enabling complete separation of the roots from the development 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 device and further increases 
the reliability of the machine. Because of this, the drive unit can be used in every placement. We has been examined under severe circumstances with high operating cycle and positive results have been Greenhouse Gear Reducer 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 part mounting, which facilitates set up and reduces the labor strength of the installation employees.
reducer furthermore to light weight, high strength aluminum alloy shell, the inner usage of a three-stage helical gear transmission, thin oil lubrication. Increased transmission effectiveness and service lifestyle. Its limit device has two types of collision block and spring sheet for customers to select. The limit adjustment can be hassle-free, and the positioning accuracy is high (especially the spring type). Can be adjusted within the range of 1~75 rpm to regulate the stop between the positive and negative of the motor. There is no double insurance switch to ensure safe operation.
1. The cabinet framework is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device gets the best wiring technique, through three micro-switches, each which functions as a brake, emergency brake, and phase error 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, thereby maximizing the amount of treatments and replications in a given space.
