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 display. The mesh supports the Turface substrate while also enabling water to 
drain by gravity. An automated watering program provides a dilute nutrient remedy to each column. The watering program is programmed to add small amounts of nutrient option at the substrate surface 20 times each day. This high frequency keeps the tops of the columns moist and ensures delivery of nutrients throughout the column.
We have developed a columnar plant lifestyle system that supports healthy plant growth while also enabling complete separation of the roots from the development substrate.
Regular potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance of drinking water and oxygen while also providing exchange areas for plant nutrition. Separation of plant roots from the potting substrate, however, is impossible.
An oil expansion chamber controls the pressure in the drive Greenhouse Gear Reducer device and further increases the reliability of the machine. As a result, the drive device can be used in every position. We has been tested under severe circumstances with high operating cycle 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom mounting and side mounting, which facilitates installation and decreases the labor strength of the installation workers.
reducer in addition to light weight, high strength aluminium alloy shell, the inner use of a three-stage helical equipment transmission, thin oil lubrication. Improved transmission performance and service existence. Its limit device offers two types of collision prevent and springtime sheet for clients to choose. The limit adjustment is usually hassle-free, and the positioning precision is high (especially the spring type). Can be adjusted within the range of 1~75 rpm to regulate the stop between your positive and negative of the electric motor. There is no double insurance switch to make sure safe operation.
1. The cabinet structure is solid, reasonable, reliable 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 better pots because they can support deep root growth while taking up much less bench space. Many columns can be arranged within a small area, like a gas-exchange chamber, thereby maximizing the amount of treatments and replications in a given space.
