Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the column, and also holds in place a mesh display. The mesh facilitates the Turface substrate while also permitting water to drain by gravity. An automated watering system delivers a dilute nutrient option to each column. The watering program is programmed to add smaller amounts of nutrient alternative at the substrate surface area 20 times per day. This high frequency retains 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.
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 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 placement. We has been tested 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 temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom mounting and part mounting, which facilitates installation and reduces the labor intensity of the installation employees.
reducer furthermore to light weight, high strength light weight aluminum alloy shell, the internal use of a three-stage helical gear transmission, thin oil lubrication. Increased transmission efficiency and service existence. Its limit device offers two types of collision block and springtime sheet for clients to choose. The limit adjustment is usually hassle-free, and the positioning precision is high (especially the spring type). Could be adjusted within the number of 1~75 rpm to regulate the stop between the positive and negative of the electric motor. There is absolutely no double insurance change to ensure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each of 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 up 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.
