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 set up a mesh display screen. The mesh facilitates the Turface substrate while also allowing drinking water to drain by gravity. An automated watering system provides a dilute nutrient solution to each column. The watering system is programmed to add small amounts of nutrient option at the substrate surface 20 times per day. This high frequency maintains the tops of the columns moist and ensures delivery of nutrients throughout the column.
We’ve developed a columnar plant tradition system that facilitates healthy plant growth 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 water and oxygen while also providing exchange surfaces 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 escalates the reliability of the unit. Because of this, the drive device can be used atlanta divorce attorneys position. We has been tested under severe conditions 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 characteristics. It adopts bottom mounting and part mounting, which facilitates installation and reduces the labor strength of the installation employees.
reducer in addition to light weight, high strength aluminum alloy shell, the inner utilization of a three-stage helical equipment transmission, thin essential oil lubrication. Increased transmission performance and service life. Its limit device has two types of collision block and springtime sheet for customers to choose. The limit adjustment is usually easy, and the positioning precision is high (specifically the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between your negative and positive of the motor. There is no double insurance change to make sure safe operation.
1. The cabinet framework is solid, reasonable, reliable performance, simple operation and maintenance
2. The limiting device gets the best wiring technique, through three micro-switches, each of which features as a brake, emergency brake, and phase mistake protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking up much less bench space. Many columns could be arranged within a little area, like a gas-exchange chamber, thereby maximizing the number of treatments and replications in a given space.
