Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the column, and also holds in place a mesh screen. The mesh supports the Turface substrate while also permitting drinking water to drain by gravity. An automated watering system delivers a dilute nutrient answer to each column. The watering system is programmed to add smaller 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 nutrients throughout the column.
We have developed a columnar plant tradition system that facilitates healthy plant development 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 an appropriate balance of drinking water and oxygen while also offering exchange areas 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 increases the reliability of the unit. Consequently, 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-Greenhouse Gear Reducer weight (about 20 kg), good temperature dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom mounting and aspect mounting, which facilitates set up and decreases the labor intensity of the installation employees.
reducer furthermore to light weight, high strength light weight aluminum alloy shell, the inner utilization of a three-stage helical gear transmission, thin oil lubrication. Improved transmission efficiency and service life. Its limit device has two types of collision prevent and spring sheet for customers to choose. The limit adjustment is definitely 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 your positive and negative of the electric motor. There is absolutely no double insurance switch 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 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 can support deep root growth while taking up less bench space. Many columns can be arranged within a little area, like a gas-exchange chamber, thereby maximizing the number of remedies and replications in confirmed space.
