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 set up a mesh display. The mesh supports the Turface substrate while also allowing drinking water to drain by gravity. An Greenhouse Gear Reducer automated watering system delivers a dilute nutrient solution to each column. The watering program is programmed to include small amounts of nutrient alternative at the substrate surface 20 times each day. This high frequency retains 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 growth substrate.
Standard potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper balance of drinking water and oxygen while also offering exchange areas 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 increases the reliability of the unit. Consequently, the drive device can be used atlanta divorce attorneys position. We has been tested 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. 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 light weight aluminum alloy shell, the internal usage of a three-stage helical equipment transmission, thin essential oil lubrication. Improved transmission efficiency and service existence. Its 
limit device provides two types of collision prevent and springtime sheet for customers to choose. The limit adjustment can be easy, and the positioning accuracy is high (specifically the spring type). Could be adjusted within the number of 1~75 rpm to regulate the stop between the negative and positive of the engine. There is no double insurance change 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 method, through three micro-switches, each of which functions 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 less bench space. Many columns could be arranged within a small area, such as a gas-exchange chamber, therefore maximizing the number of treatments and replications in confirmed space.
