Our columns are made 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 facilitates the Turface substrate while also permitting water to drain by gravity. An automated watering system delivers a dilute nutrient remedy to each column. The watering system is programmed to add small amounts of nutrient option at the substrate surface 20 times per day. This high frequency will keep the tops of the columns moist and ensures delivery of nutrients 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.
Standard potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance of drinking 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 device and further escalates the reliability of the unit. Because of this, 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 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 features. It adopts bottom mounting and aspect mounting, which facilitates installation and decreases the labor intensity of the installation workers.
reducer in addition to light weight, high strength aluminium alloy shell, the inner use of a three-stage helical gear transmission, thin oil lubrication. Improved transmission effectiveness and service life. Its limit device has two types of collision prevent and spring sheet for customers 
to choose. The limit adjustment is usually practical, and the positioning accuracy is high (especially the spring type). Can be adjusted within the range of 1~75 rpm to regulate the stop between your negative and positive of the engine. There is absolutely no double insurance change to make sure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple procedure and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each which functions as a brake, emergency brake, and phase mistake protection
Columnar containers are better pots because they can support deep root growth while taking on less bench space. Many columns can be arranged within a small area, like a gas-exchange chamber, thereby maximizing the amount of remedies and replications in a given space.
