Q1: What are the different types of glazing for Greenhouse?
A: The most common types of glazing are glass, polycarbonate, and polyethylene films. Glass is the longest lasting of the glazing, particularly if the glass is tempered. It is expensive relative to other two. It transmits light very well, but it does not diffuse light very well (may result in shadowing and plant burn if not carefully dealt with).
Polycarbonate (PC) generally comes in twinwall or even triplewall sheets in thicknesses from 4-16mm.
PC is easy to cut, and has a high degree of light transmittance and low thermal IR transmittance. Light is diffused with PC. PC lasts 15-20 years.
Polyethylene (PE) films are relatively inexpensive and are the easiest with which to work. Light is transmitted and diffused well. PE with infrared additives reduces heat loss at night. The lifespan of PE films is generally about 3-5 years.
Other les commonly used glazings includes acrylic, fiberglass, and PVC.
Q2: What is shade cloth and do I need it on my greenhouse?
A: If your greenhouse locates in a humid area, misting or fogging may not be enough to cool your greenhouse in those hot, humid summer months. When all else fails you can create your own shade by putting the shade cloth on your greenhouse.
Shade cloth is usually made of loosely woven or knitted polyester or even aluminum foil. Densities or degrees of shade from appx. 5% to 95% are available for different plant needs.
Shade cloth can be installed exterior (on top of) the greenhouse with extra frame structure, or interior the greenhouse by hanging to the greenhouse pillars. Exterior shading is more expensive to build than that of interior, but exterior shading has better shading effect (cooling effect) than the interior shading.
Q3: What is the fan + evaporated pad cooling system and do I need it on my greenhouse?
A: Fan and pad systems consist of exhaust fans at one end of the greenhouse and a pump circulating water through and over a porous pad installed at the opposite end of the greenhouse.If all vents and doors are closed when the fans operate, air is pulled through the wetted pads and water evaporates. As each gallon of water is evaporated, 8,100 BTUs of heat energy is absorbed from the air by the water during the change from liquid to vapor. Removing energy from the air lowers the temperature of the air being introduced into the greenhouse.
The air temperature reduces after passing through the pads. As the air moves across the house to the fans, it picks up heat from solar radiation, plants, and soil, and the temperature of air increases gradually. The resulting temperature increases as air moves down the greenhouse & produces a temperature gradient across the length of the greenhouse, with the pad side being coolest and the fan side warmest.
Q4: I don’t have greenhouse experience before, how can I install the greenhouse that I buy form you?
A: The greenhouse we design are easy & quick to be installed with simple tools: hammer, drill, cutters, wrenches and etc. Detailed installation manual, with clear drawings and descriptions will be provided. If necessary, Kunyu would send technician(s) to your place and provide installation technical support.
Q5: Are there books that can help me get started with the greenhouse growing business?
A: We can send engineers to the job site for greenhouse installation.
