Our columns are constructed of 2” diameter PVC pipe. A bell-shaped reducer fitting secured 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 delivers a dilute nutrient option to each column. The watering system is programmed to add smaller amounts of nutrient alternative at the substrate surface 20 times per day. This high frequency maintains the tops of the columns moist and ensures delivery of nutrition 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 blended with perlite or vermiculite. These well-drained, organic-wealthy mixtures support an 
appropriate balance of water and oxygen while also providing 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 escalates the reliability of the unit. As a result, the drive unit can be used atlanta divorce attorneys Greenhouse Gear Reducer placement. We has been tested under severe circumstances with high operating cycle 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 set up and decreases the labor strength of the installation employees.
reducer in addition to light weight, high strength aluminium alloy shell, the internal use of a three-stage helical equipment transmission, thin oil lubrication. Improved transmission efficiency and service life. Its limit device provides two types of collision prevent and springtime sheet for customers to select. The limit adjustment can be convenient, and the positioning precision is high (especially the spring type). Can be adjusted within the range of 1~75 rpm to control the stop between the negative and positive of the motor. There is no double insurance switch 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 error protection
Columnar containers are better pots because they are able to support deep root growth while taking on much less bench space. Many columns could be arranged within a little area, such as a gas-exchange chamber, therefore maximizing the number of treatments and replications in a given space.
