Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and in addition holds set up a mesh screen. The mesh supports the Turface substrate while also permitting water to drain by gravity. An automated watering system provides a dilute nutrient remedy to each column. The watering system is programmed to add smaller amounts of nutrient alternative at the substrate surface 20 times each 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 facilitates healthy plant development while also enabling complete separation of the roots from the growth substrate.
Standard potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-rich mixtures support a proper balance 
of drinking 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 device and further escalates the reliability of the machine. As a result, the drive device can be used atlanta divorce attorneys placement. We has been tested under severe circumstances with high operating routine 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 level mounting and side mounting, which facilitates installation and reduces the labor intensity 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 oil lubrication. Increased transmission effectiveness and service life. Its limit device provides two types of collision block and springtime sheet for clients to choose. The limit adjustment is usually easy, and the positioning accuracy is high (especially the spring type). Could be adjusted within the number of 1~75 rpm to control the stop between the positive and negative of the electric motor. There is no double insurance change to make sure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device has the best wiring method, through three micro-switches, each 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 less bench space. Many columns can be arranged within a little area, like a gas-exchange chamber, therefore maximizing the amount of treatments and replications in confirmed space.
