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 in addition holds set up a mesh screen. The mesh supports the Turface substrate while also allowing drinking water to drain by gravity. An automated watering program provides a dilute nutrient remedy to each column. The watering program is programmed to add small amounts of nutrient answer at the substrate surface area 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 facilitates healthy plant development while also enabling complete separation of the roots from the development substrate.
Standard potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-rich mixtures support an appropriate balance of drinking 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 device and further increases the reliability of the machine. Consequently, the drive unit 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 temperature dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom level mounting and part mounting, which facilitates set up and decreases the labor intensity of the installation employees.
reducer furthermore to light-weight, high strength light weight aluminum alloy shell, the inner utilization of a three-stage helical gear transmission, thin essential oil lubrication. Increased transmission efficiency and service lifestyle. Its limit device offers two types of collision prevent and springtime sheet for clients to select. The limit adjustment is practical, and the positioning precision is high (specifically the spring type). Could be adjusted within the range of 1~75 rpm to control the stop between the negative and positive of the engine. There is absolutely no double insurance switch to make sure 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 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 less bench space. Many columns could be arranged within a Greenhouse Gear Reducer little area, such as a gas-exchange chamber, thereby maximizing the number of remedies and replications in confirmed space.
