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 set up a mesh screen. The mesh facilitates the Turface substrate while also allowing water to drain 
by gravity. An automated watering system delivers a dilute nutrient option to each column. The watering program is programmed to include small amounts of nutrient option at the substrate surface area 20 times per 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 facilitates 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-wealthy mixtures support a proper balance of drinking water and oxygen while also providing exchange areas for plant nutrition. Separation of plant roots from the potting substrate, however, is impossible.
An oil expansion chamber controls the pressure in the drive device and further increases the reliability of the machine. Consequently, the drive device can be used atlanta divorce attorneys placement. We has been examined under severe circumstances 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom mounting and part mounting, which facilitates set up and reduces the labor strength of the installation workers.
reducer furthermore to light-weight, high strength light weight aluminum alloy shell, the internal utilization 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 block and springtime sheet for clients to choose. The limit adjustment is certainly convenient, and the positioning accuracy is high (especially the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between your negative and positive of the electric motor. There is absolutely no double insurance switch to ensure safe operation.
1. The cabinet structure is solid, reasonable, reliable performance, simple procedure 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 preferable to pots because they can support deep root growth while taking up less bench space. Many columns could be arranged within a little area, such as a gas-exchange chamber, therefore maximizing the amount of treatments and replications in confirmed space.
