Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the column, and in addition holds set up a mesh display. The mesh facilitates the Turface substrate while also enabling water to drain by gravity. An automated watering system delivers a dilute nutrient solution to each column. The watering system is programmed to include smaller amounts of nutrient answer 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 tradition system that supports 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 water and oxygen while also providing 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 unit and further increases the reliability of the unit. As a result, the drive unit can be used in every position. We has been examined under severe conditions with high operating routine and positive 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 characteristics. It adopts bottom level mounting and aspect mounting, which facilitates set up and reduces the labor intensity of the installation employees.
reducer furthermore to light-weight, high strength aluminium alloy shell, the inner use of a three-stage helical equipment transmission, thin essential oil lubrication. Increased transmission effectiveness and service existence. Its limit device offers two types of collision block and spring sheet for customers to select. The limit adjustment is usually convenient, and the positioning accuracy is high (especially the spring type). Could be adjusted within the range of 1~75 rpm to regulate the stop between the negative and positive of the electric motor. There is absolutely no double insurance switch to make sure safe operation.
1. The cabinet framework is solid, reasonable, reliable performance, simple procedure 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 error protection
Columnar containers are better pots because they are able to support deep root growth while taking up less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the amount of remedies and replications in a given space.
