Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting secured to underneath of the pipe stabilizes the column, and also holds in place a mesh screen. The mesh facilitates the Turface substrate while also permitting drinking water to drain by gravity. An automated watering system provides a dilute nutrient option to each column. The watering program is 
programmed to include small amounts of nutrient Greenhouse Gear Reducer answer at the substrate surface area 20 times each day. This high frequency continues the tops of the columns moist and ensures delivery of nutrients throughout the column.
We have developed a columnar plant tradition system that supports healthy plant growth while also enabling complete separation of the roots from the development substrate.
Standard potting substrates typically contain sphagnum peat mixed with perlite or vermiculite. These well-drained, organic-rich mixtures support an appropriate 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 in every placement. We has been examined under severe circumstances with high operating cycle and positive 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 characteristics. It adopts bottom mounting and part mounting, which facilitates set up and decreases the labor intensity of the installation workers.
reducer furthermore to light-weight, high strength aluminium alloy shell, the internal utilization of a three-stage helical equipment transmission, thin oil lubrication. Improved transmission effectiveness and service life. Its limit device provides two types of collision block and spring sheet for customers to choose. The limit adjustment is certainly practical, 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 the positive and negative of the electric motor. There is no double insurance change to make sure safe operation.
1. The cabinet structure is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each of which functions as a brake, emergency brake, and phase mistake 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 confirmed space.
