Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and in addition 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 provides a dilute nutrient alternative 
to each column. The watering system is programmed to add small amounts of nutrient alternative at the substrate surface area 20 times each day. This high frequency continues the tops of the columns moist and ensures delivery of nutrition throughout the column.
We have developed a columnar plant tradition system that supports 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-wealthy mixtures support a proper balance of water and oxygen while also providing 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 escalates the reliability of the unit. Because of this, the drive unit can be used in every position. We has been tested under severe circumstances 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 heat dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom level mounting and aspect mounting, which facilitates set up and reduces the labor intensity of the installation workers.
reducer in addition to light weight, high strength light weight aluminum alloy shell, the internal use of a three-stage helical equipment transmission, thin oil lubrication. Increased Greenhouse Gear Reducer transmission effectiveness and service life. Its limit device has two types of collision block and springtime 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 control the stop between your positive and negative of the motor. There is no double insurance switch to make sure safe operation.
1. The cabinet framework is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device gets the best wiring method, through three micro-switches, each 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 up less bench space. Many columns can be arranged within a little area, like a gas-exchange chamber, therefore maximizing the amount of remedies and replications in a given space.
