Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed to underneath of the pipe stabilizes the column, and also holds in place a mesh display screen. The mesh facilitates the Turface substrate while also permitting drinking water to drain by gravity. An automated watering program delivers a dilute nutrient alternative to each column. The watering system is programmed to add small amounts of nutrient answer at the substrate surface 20 times per day. This high frequency maintains the tops of the columns moist and ensures delivery of nutrients throughout the column.
We have developed a columnar plant culture 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 mixed with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper 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. As a result, the drive device can be used atlanta divorce attorneys 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 high temperature dissipation, output torque (400N.m ~ 800N. m), low noise characteristics. It adopts bottom level mounting and side mounting, which facilitates set up and decreases the labor strength of the installation workers.
reducer furthermore to light weight, high strength light weight aluminum alloy shell, the internal use of a three-stage helical gear transmission, thin oil lubrication. Improved transmission performance and service life. Its limit device has two types of collision block and springtime sheet for clients to choose. The limit adjustment is usually practical, and the positioning accuracy is high (especially the spring type). Can be adjusted within the range of 1~75 rpm to regulate the stop between the positive and negative of the motor. There is no double insurance change to make sure safe operation.
1. The cabinet framework 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 mistake protection
Columnar containers are preferable to pots because they are able to support deep root growth while taking on 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 a given space.
