Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to the bottom of the pipe stabilizes the column, and also holds in place a mesh display screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An automated watering program provides a dilute nutrient answer to each column. The watering system is programmed to include smaller amounts of nutrient alternative at the substrate surface 20 times per day. This high frequency will keep the tops of the columns moist and ensures delivery of nutrition throughout the column.
We have developed a columnar plant lifestyle system that facilitates healthy plant development while also enabling complete separation of the roots from the growth substrate.
Regular potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper balance of water and oxygen while also offering 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. As a result, the drive unit can be used in every placement. We has been tested under severe circumstances with high operating cycle and positive 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 characteristics. It adopts bottom level mounting and part mounting, which facilitates set up and decreases the labor intensity of the installation workers.
reducer furthermore to light-weight, high strength aluminium alloy shell, the inner usage of a three-stage helical gear transmission, thin essential oil lubrication. Improved transmission effectiveness and service existence. Its limit device Greenhouse Gear Reducer offers two types of collision block and spring sheet for customers to choose. The limit adjustment can be hassle-free, and the positioning accuracy is high (specifically the spring type). Can be adjusted within the range of 1~75 rpm to control the stop between your positive and negative of the electric motor. There is absolutely no 
double insurance change to ensure safe operation.
1. The cabinet framework is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device gets the best wiring technique, through three micro-switches, each of which functions as a brake, emergency brake, and phase error protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking on 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 confirmed space.
