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 in addition holds set up a mesh screen. The mesh facilitates the Turface substrate while also allowing water to drain by gravity. An automated watering program delivers a dilute nutrient answer to each column. The watering program is programmed to include small amounts of nutrient alternative at the substrate surface area 20 times per day. This high frequency will keep the tops of the columns moist and ensures Greenhouse Gear Reducer delivery of nutrition throughout the column.
We have developed a columnar plant lifestyle system that supports healthy plant development 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-rich mixtures support a proper balance of water and oxygen while also offering 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 device and further escalates the reliability of the unit. As a result, the drive device can be used in every placement. We has been examined under severe conditions 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 characteristics. It adopts bottom mounting and side mounting, which facilitates installation and decreases the labor strength 
of the installation workers.
reducer furthermore to light-weight, high strength aluminum alloy shell, the inner use of a three-stage helical equipment transmission, thin essential oil lubrication. Increased transmission efficiency and service life. Its limit device provides two types of collision block and spring sheet for clients to choose. The limit adjustment is definitely easy, and the positioning precision is high (specifically the spring type). Could be adjusted within the range of 1~75 rpm to regulate the stop between your negative and positive of the motor. There is absolutely no double insurance switch to make sure safe operation.
1. The cabinet structure 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 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 can be arranged within a little area, like a gas-exchange chamber, therefore maximizing the number of treatments and replications in a given space.
