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 in place a mesh display screen. The mesh facilitates the Turface substrate while also allowing drinking water to drain by gravity. An automated watering system delivers a dilute nutrient option to each column. The watering program is programmed to include smaller amounts of nutrient answer 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 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 growth substrate.
Regular potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support an appropriate balance of water and oxygen while also providing exchange surfaces 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 unit can be used in every placement. We has been examined under severe circumstances 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 characteristics. 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 internal usage of a three-stage helical gear transmission, thin oil lubrication. Increased transmission effectiveness and service lifestyle. Its limit device provides two types of collision block and spring sheet for clients to select. 
The limit adjustment can be convenient, and the positioning precision is high (specifically the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between the negative and positive of the motor. There is no double insurance switch to ensure safe operation.
1. The cabinet framework 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 error protection
Columnar containers are preferable to pots because they can support deep root growth while taking up much less bench space. Many columns could be arranged within a small area, like a gas-exchange chamber, thereby maximizing the number of remedies and replications in a given space.
