Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to the bottom of the pipe stabilizes the column, and in addition holds in place a mesh screen. The mesh supports the Turface substrate while also allowing water to drain by gravity. An automated watering system delivers a dilute nutrient solution to each column. The watering program is programmed to include small amounts of nutrient solution at the substrate surface 20 times per day. This high frequency keeps the tops of the columns moist and ensures delivery of nutrients throughout the column.

We have developed a columnar plant culture 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 an appropriate balance of drinking water and oxygen while also providing exchange Greenhouse Gear Reducer 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 unit and further increases the reliability of the unit. Because of this, the drive device can be used in every placement. We has been examined under severe circumstances with high operating cycle and excellent 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 features. It adopts bottom level mounting and part mounting, which facilitates installation and reduces the labor strength of the installation workers.
reducer in addition to light-weight, high strength aluminium alloy shell, the internal utilization of a three-stage helical equipment transmission, thin essential oil lubrication. Increased transmission effectiveness and service lifestyle. Its limit device offers two types of collision prevent and spring sheet for clients to choose. The limit adjustment can be 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 change 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 method, through three micro-switches, each of which features as a brake, emergency brake, and phase mistake protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking on less bench space. Many columns could be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the number of treatments and replications in a given space.
