Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and also holds in place a mesh display. The mesh facilitates the Turface substrate while also enabling water to drain by gravity. An automated watering program delivers a dilute nutrient answer to each column. The watering program is programmed to include smaller amounts of nutrient remedy at the substrate surface area 20 times per day. This high frequency continues 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-wealthy 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 device and further escalates 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 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom mounting and side 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 usage of a three-stage helical gear transmission, thin essential oil lubrication. Increased transmission efficiency and service life. Its limit device has two types of collision block and springtime sheet for customers to choose. The limit adjustment is usually hassle-free, and the positioning accuracy is high (specifically the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between the positive and negative of the electric motor. There is absolutely no double insurance change to make sure safe operation.
1. The cabinet framework is solid, reasonable, dependable performance, simple procedure and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each of which functions as a brake, Greenhouse Gear Reducer emergency brake, and phase error protection
Columnar containers are better 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, therefore maximizing the amount of remedies and replications in a given space.
