• It has an effect of coating restraint by getting a large amount of light to backside of leaf through maximization of photosynthesis within a short period of time from germination to the unfolding of foliage leaf.

Restraint effect of generation of of disease harmful insect on the initial stage of rearing of seeling

• Phenomenon of inhabitation avoidance of aphid, mite, moth and fly parasitic on backside of leaf during the initial stage of rearing of seedling and phenomenon of avoidance of disease generation of germs propagating to pore and strain.

Surrounding temperature adjustment effect during winter, summer

• Regarding the surface temperature of tray, since the temperature of silver tray is lower than that of general tray (approximately 5~7 degrees), it can reduce stress of root zone and decrease risk of disease by lowering humidity of above-ground part(air).
• By increasing temperature inside the tunnel within a short period of time for rearing of seedling in winter, it is excellent in temperature management and makes it easy to manage cold-weather damage and low temperature stress.
