Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to the bottom of the pipe stabilizes the column, and in addition holds set up a mesh screen. The mesh facilitates the Turface substrate while also enabling drinking water to drain by gravity. An 
automated watering system provides a dilute nutrient answer to each column. The watering system is programmed to include smaller amounts of nutrient solution at the substrate surface area 20 times each day. This high frequency keeps the tops of the columns moist and ensures delivery of nutrients throughout the column.
We have developed a columnar plant tradition system that supports 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-wealthy mixtures support an appropriate balance of drinking water and oxygen while also offering 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 device and further escalates the reliability of the machine. Because of this, the drive unit 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 heat dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. 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 oil lubrication. Increased transmission effectiveness and service lifestyle. Its limit device provides two types of collision block and springtime sheet for clients to select. The limit adjustment is convenient, and the positioning precision is high (especially the spring type). Could be adjusted within the number of 1~75 rpm to control the stop between your negative and positive of the engine. There is absolutely no double insurance change to ensure safe operation.
1. The cabinet structure is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device gets the best wiring technique, 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 can support deep root growth while taking up much less bench space. Many columns could be arranged within a small area, like a gas-exchange chamber, thereby maximizing the amount of treatments and replications in confirmed space.
