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. The mesh supports the Turface substrate while also allowing water to drain by gravity. An automated watering program delivers a dilute nutrient alternative to each column. The watering program is programmed to include smaller amounts of nutrient alternative at the substrate surface 20 times per day. This high frequency retains the tops of the columns moist and ensures delivery of nutrition throughout the column.
We’ve developed a columnar plant lifestyle system that facilitates healthy plant growth while also enabling complete separation of the roots from the development substrate.
Standard potting substrates typically contain sphagnum peat blended with perlite or vermiculite. These well-drained, organic-wealthy mixtures support a proper 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 machine. Consequently, the drive device can be used in every placement. We has been tested under severe circumstances with high operating cycle and excellent results have been achieved.
The new type 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 mounting and aspect 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 inner utilization of a three-stage helical gear transmission, thin essential oil lubrication. Improved transmission effectiveness and service existence. Its limit device provides two types of collision block and springtime sheet for clients to choose. The limit adjustment is definitely hassle-free, and the positioning precision is high (Greenhouse Gear Reducer especially the spring type). Can be adjusted within the number of 1~75 rpm to regulate the stop between the positive and negative of the engine. There is no double insurance switch to ensure 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 features 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 much less bench space. Many columns could be arranged within a small area, such as a gas-exchange chamber, therefore maximizing the amount of treatments and replications in confirmed space.
