Our columns are made 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 screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An automated watering system delivers a dilute nutrient remedy to each column. The watering program is programmed to add small amounts of nutrient remedy at the substrate surface area 20 times each day. This high frequency helps to keep the tops of the columns moist and ensures delivery of nutrients throughout the column.

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

Regular potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance of drinking 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 machine. Because of this, the drive device can be used in every placement. 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom mounting and side mounting, which facilitates set up and reduces the labor intensity of the installation employees.
reducer in addition to light weight, high strength light weight aluminum alloy shell, the inner usage of a three-stage helical equipment transmission, thin oil lubrication. Increased transmission effectiveness and service life. Its limit device offers two types of collision block and springtime sheet for clients to choose. The limit adjustment is certainly practical, and the positioning precision is high (especially the spring type). Can 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 structure is solid, reasonable, reliable performance, simple procedure 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 are able to support deep root growth while taking on much less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the number of treatments and replications in confirmed space.
