Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to the bottom of the pipe stabilizes the column, and also holds in place a mesh display screen. The mesh supports 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 program is programmed to add smaller amounts of 
nutrient solution at the substrate surface 20 times per 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 culture system that supports 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-rich mixtures support an appropriate 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 Greenhouse Gear Reducer further escalates the reliability of the machine. Because of this, the drive unit can be used atlanta divorce attorneys placement. We has been examined under severe conditions with high operating routine and excellent 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 warmth dissipation, output torque (400N.m ~ 800N. m), low noise features. It adopts bottom level mounting and part mounting, which facilitates installation and decreases the labor strength of the installation employees.
reducer in addition to light-weight, high strength aluminium alloy shell, the inner use of a three-stage helical gear transmission, thin oil lubrication. Improved transmission effectiveness and service lifestyle. Its limit device has two types of collision block and springtime sheet for clients to select. The limit adjustment is hassle-free, 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 positive and negative of the motor. There is no double insurance switch to make sure safe operation.
1. The cabinet framework 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 error protection
Columnar containers are better pots because they can support deep root growth while taking on much less bench space. Many columns can be arranged within a little area, like a gas-exchange chamber, thereby maximizing the amount of treatments and replications in a given space.
