Our columns are constructed 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 facilitates the Turface substrate while also permitting 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 remedy at the substrate surface area 20 times each day. This high frequency helps to keep 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 growth while also enabling complete separation of the roots from the growth substrate.
Regular potting substrates typically contain sphagnum peat mixed 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 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 unit can be used in every placement. We has been examined under severe conditions 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 temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom level mounting and part mounting, which facilitates installation and decreases the labor strength of the installation employees.
reducer furthermore to light weight, high strength aluminum alloy shell, the inner use of a three-stage helical gear transmission, thin essential oil lubrication. Increased transmission effectiveness and service life. Its limit device offers two types of collision prevent and springtime sheet for clients to choose. The limit adjustment can be easy, and the positioning accuracy is high (specifically the spring type). Can be adjusted within the range of 1~75 rpm to control the stop between the positive and negative of the electric motor. There is no double insurance switch to ensure safe operation.
1. The cabinet structure is solid, reasonable, reliable 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, emergency brake, and phase error protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking on much less bench space. Many columns could be arranged within a little area, like a gas-exchange chamber, therefore maximizing the amount of treatments and replications in a given space.
