Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and also holds in place a mesh screen. The mesh facilitates the Turface substrate while also permitting drinking water to drain by gravity. An automated watering program delivers a dilute nutrient solution to each column. The watering system is programmed to add small amounts of nutrient option at the substrate surface 20 times per day. This high frequency maintains 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 growth while also enabling complete separation of the roots from the growth substrate.
Standard potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper 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 unit. 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 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 essential oil lubrication. Increased transmission performance and service lifestyle. Its limit device has two types of collision block and springtime sheet for clients to select. The limit adjustment can be hassle-free, and the positioning precision is high (especially the spring type). Can be adjusted within the number 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 structure 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.
