Our columns are made of 2” diameter PVC pipe. A bell-shaped Greenhouse Gear Reducer reducer fitting secured to the bottom of the pipe stabilizes the column, and also holds set up a mesh screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An automated watering system provides a dilute nutrient remedy to each column. The watering system is programmed to include smaller amounts of nutrient remedy at the substrate surface 20 times per day. This high frequency maintains the tops of the columns moist and ensures delivery of nutrition throughout the column.

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

Standard potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance of water and oxygen while also offering exchange surfaces for plant nutrients. 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 machine. As a result, the drive unit 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 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 aluminium alloy shell, the inner use of a three-stage helical equipment transmission, thin oil lubrication. Improved transmission efficiency and service existence. Its limit device has two types of collision block and spring sheet for clients to choose. The limit adjustment can be hassle-free, and the positioning precision is high (specifically the spring type). Could be adjusted within the number of 1~75 rpm to control the stop between the negative and positive of the engine. There is absolutely no double insurance switch to ensure safe operation.

1. The cabinet framework is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each of 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 less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, therefore maximizing the number of treatments and replications in confirmed space.
