Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and in addition holds set up a mesh display screen. The mesh facilitates the Turface substrate while also allowing drinking water to drain by gravity. An automated watering program provides a dilute nutrient option to each column. The watering program is programmed to include small amounts of nutrient option at the substrate surface 20 times per day. This high frequency helps to keep the tops of the columns moist and ensures delivery of nutrition throughout the column.

We’ve developed a columnar plant tradition system that facilitates healthy plant growth while also enabling complete separation of the roots from the development substrate.

Regular potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support an appropriate balance of drinking 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 unit and further escalates the reliability of the unit. Consequently, the drive unit can be used in every position. We has been examined under severe conditions with high operating routine 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 mounting and part mounting, which facilitates set up and decreases the labor strength of the installation workers.
reducer in addition to light-weight, high strength light weight aluminum alloy shell, the internal usage of a three-stage helical equipment transmission, thin oil lubrication. Improved transmission effectiveness and service existence. Its limit device offers two types of collision prevent and springtime 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 number of 1~75 rpm to regulate the stop between the negative and positive of the motor. There is no double insurance change to ensure safe operation.

1. The cabinet structure is solid, reasonable, dependable performance, simple operation 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 mistake protection
Columnar containers are preferable to pots because they can support deep root growth while taking on much 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 confirmed space.
