Our columns are made of 2” diameter PVC pipe. A bell-shaped reducer fitting guaranteed 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 water to drain by gravity. An automated watering program delivers a dilute nutrient option 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 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 development 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 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 escalates the reliability of the unit. Consequently, the drive device can be used in every placement. We has been tested under severe conditions 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 level mounting and part mounting, which facilitates set up and reduces the labor intensity of the installation employees.
reducer in addition to light weight, high strength light weight aluminum alloy shell, the internal utilization of a three-stage helical equipment transmission, thin essential oil lubrication. Increased transmission effectiveness and service life. Its limit device has two types of collision prevent and springtime sheet for clients to select. The limit adjustment is certainly easy, and the positioning precision is high (especially the spring type). Could be adjusted within the range of 1~75 rpm to regulate the stop between the negative and positive of the engine. There is absolutely no double insurance change to make sure safe operation.

1. The cabinet framework is solid, reasonable, dependable performance, simple operation and maintenance
2. The limiting device has the best wiring technique, through three micro-switches, each which features as a brake, emergency brake, and phase error protection
Columnar containers are preferable to pots because they can 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, thereby maximizing the number of remedies and replications in confirmed space.
