Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to the bottom of the pipe stabilizes the column, and in addition holds in place a mesh display. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An automated watering system provides a dilute nutrient option to each column. The watering program is programmed to include small amounts of nutrient answer at the substrate surface area 20 times each day. This high frequency retains the tops of the columns moist and ensures delivery of nutrition throughout the column.
We’ve developed a columnar plant tradition system that supports healthy plant growth while also enabling complete separation 
of the roots from the growth substrate.
Standard potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-wealthy mixtures support an appropriate 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 unit and further escalates the reliability of the machine. Because of this, the drive unit can be used in every placement. We has been examined under severe conditions 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 heat dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom mounting and part mounting, which facilitates set up and decreases the labor intensity of the installation workers.
reducer furthermore to light weight, high strength aluminium alloy shell, the inner utilization of a three-stage helical gear transmission, thin oil lubrication. Increased transmission efficiency and service life. Its limit device provides two types of collision prevent and spring sheet for clients to select. The limit adjustment is certainly convenient, and the positioning accuracy is high (especially the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between your positive and negative of the motor. There is no double insurance change to ensure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device has the best wiring method, through three micro-switches, each 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 up much less bench space. Many columns can be arranged within a little area, such as a gas-exchange chamber, therefore maximizing the number of treatments and replications in a given space.
