Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and also holds set up a mesh screen. The mesh supports the Turface substrate while also allowing water to drain by gravity. An automated watering program provides a dilute nutrient answer to each column. The watering system is programmed to add smaller amounts of nutrient remedy at the substrate surface 20 times per day. This high frequency continues the tops of the columns moist and ensures delivery of nutrients throughout the column.
We’ve 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 an appropriate balance of water and oxygen while also providing exchange surfaces for plant nutrition. 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 machine. Consequently, the drive device can be used in every position. We has been examined under severe circumstances with high operating cycle and positive results have been achieved.
The new kind 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 temperature dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom level mounting and 
part mounting, which facilitates installation and reduces the labor strength of the installation workers.
reducer in addition to light-weight, high strength aluminum alloy shell, the inner use of a three-stage helical gear transmission, thin essential oil lubrication. Improved transmission effectiveness and service existence. Its limit device provides two types of collision prevent and spring sheet for clients to choose. The limit adjustment is convenient, and the positioning accuracy is high (especially the spring type). Could be adjusted within the range of 1~75 rpm to control the stop between the positive and negative of the engine. There is absolutely no double insurance switch to make sure safe operation.
1. The cabinet framework is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each which features as a brake, emergency brake, and phase mistake protection
Columnar containers are better pots because they are able to support deep root growth while taking up 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 confirmed space.
