Our 
columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and also holds in place a mesh screen. The mesh facilitates the Turface substrate while also permitting water to drain by gravity. An automated watering system provides a dilute nutrient alternative to each column. The watering system is programmed to include small amounts of nutrient alternative at the substrate surface area 20 times each day. This high frequency continues 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-wealthy mixtures support an appropriate balance of 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 device can be used in every position. We has been examined under severe circumstances 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 warmth dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom level mounting and aspect mounting, which facilitates set up and decreases the labor intensity of the installation employees.
reducer furthermore to light-weight, high strength aluminum alloy shell, the internal utilization of a three-stage helical equipment transmission, thin oil lubrication. Increased transmission efficiency and service existence. Its limit device provides two types of collision prevent and spring sheet for customers to choose. The limit adjustment is certainly easy, and the positioning accuracy is high (especially the spring type). Could be adjusted within the range of 1~75 rpm to control the stop between your positive and negative of the electric motor. There is no double insurance switch to ensure 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 which features 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 much less bench space. Many columns could be arranged within a little area, such as a gas-exchange chamber, thereby maximizing the number of treatments and replications in a given space.
