Our columns are constructed 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 facilitates the Turface substrate while also allowing drinking water to drain by gravity. An automated watering system delivers a dilute nutrient solution to each column. The watering program is programmed to add small amounts of nutrient remedy at the substrate surface area 20 times per day. This high frequency maintains 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.
Standard potting substrates typically contain sphagnum peat mixed 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 unit and further escalates the reliability of the unit. Consequently, the drive device can be used in every placement. We has been examined under severe conditions with high operating cycle 
and excellent results have been achieved.
The new kind 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 installation and decreases the labor strength of the installation employees.
reducer in addition to light weight, high strength aluminum alloy shell, the internal use of a three-stage helical equipment transmission, thin oil lubrication. Increased transmission effectiveness and service life. Its limit device has two types of collision block and spring sheet for customers to choose. The limit adjustment is definitely convenient, and the positioning precision is high (specifically the spring type). Can be adjusted within the range of 1~75 rpm to control the stop between the positive and negative of the engine. There is absolutely 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 gets the best wiring technique, through three micro-switches, each of which features as a brake, emergency brake, and phase error protection
Columnar containers are better pots because they can support deep root growth while taking up less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the amount of remedies and replications in confirmed space.
