Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the Greenhouse Gear Reducer column, and in addition holds set up a mesh display. The mesh supports the Turface substrate while also enabling water to drain by gravity. An automated watering system delivers a dilute nutrient alternative to each column. The watering system is programmed to add smaller amounts of nutrient answer at the substrate surface 20 times per day. This high frequency retains the tops of the columns moist and ensures delivery of nutrients throughout the column.
We have developed a columnar plant tradition system that facilitates healthy plant growth 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 a proper balance of water and oxygen while also providing 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 unit and further escalates the reliability of the machine. Because of this, the drive unit can be used atlanta divorce attorneys placement. We has been tested under severe conditions with high operating 
routine 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 heat dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom mounting and aspect mounting, which facilitates installation and reduces the labor intensity of the installation employees.
reducer in addition to light weight, high strength light weight aluminum alloy shell, the internal utilization of a three-stage helical gear transmission, thin oil lubrication. Improved transmission performance and service life. 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). Can be adjusted within the number of 1~75 rpm to control the stop between the negative and positive of the motor. There is absolutely no double insurance change to make sure safe operation.
1. The cabinet framework is solid, reasonable, reliable performance, simple operation 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 mistake protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking up less bench space. Many columns could be arranged within a little area, like a gas-exchange chamber, thereby maximizing the number of treatments and replications in a given space.
