The "White Paper on China's Laminated Timber Flooring Consumption" issued jointly by the Flooring Committee of the China Forest Products Industry Association and the Consumer Guiding Working Committee of the China Consumers Association pointed out that the hardwood flooring should be durable and require surface abrasion resistance, density, static bending strength, and moisture content. And other 17 physical and chemical performance indicators. When consumers buy floorboards, they must understand each indicator very clearly and more difficultly. After consultation with the experts on the floor of the Holy Scriptures, consumers can focus on the following three criteria, so they can avoid detours and can easily purchase and use them. floor.
Surface abrasion: The higher the abrasion resistance level, the less likely the floor will scratch the surface and the longer the service life. The surface of the laminate flooring is a layer of aluminum oxide wear-resisting layer that cannot be repaired once it is destroyed, and the floor is also declared obsolete. The quality of the wear layer is not measured in terms of thickness, but is determined by the content and purity of aluminum oxide per square meter. The national standard stipulates that the level of wear of households using floors must be AC3 (more than or equal to 6,000 rpm), and public places must use AC4 (more than or equal to 9,000 rpm). Therefore, when purchasing laminate flooring, do not overlook the level of wear on the floor surface due to price factors.
Formaldehyde release limit: According to the national standard 18580-2001, the formaldehyde release limit of laminate flooring must reach E1 level, that is, the formaldehyde emission is less than or equal to 1.5mg/L (dryer method). This is the most basic requirement and products that meet this standard can be safely used in an indoor environment. At present, the international adoption is a higher environmental protection standard E0, that is, formaldehyde emission is less than or equal to 0.5mg/L. At present, the health floor has become the mainstream of consumption. In the year of 2004, Shengxiang built a healthy substrate production line. The average floor formaldehyde emission limit of the produced floor substrate is less than or equal to 0.5mg/L, and the floor is healthy from the inside to the surface.
Installation standards: Three points seven floors installed. In the past, there were no specific regulations for floor installation. This year will be the normative year for the wood floor covering market. The national standard is "Wood floor pavement specification" GB/T20238-2006 and the Ministry of Construction "Wood floor pavement technical specification" (CECS191:2005 ) has been introduced at the same time, will make the wood flooring shop with a chapter to follow. The first batch of St. John's floor installation technicians will continue to hold certificates through the training and examinations of the Ministry of Construction, the China Forest Products Industry Association, and the China Engineering Construction Standardization Committee.

Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although LED Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED grow lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.
Yields! With a quality Grow light and an average-to-good grow,you can expect yields of about 0.5g/watt. It depends a lot on strain,and pro growers can yield even more,but that's a good rule of thumb.As an example, a 200W LED (200W true power draw, not an "equivalent" wattage) would yield about 100 grams on average, or 3.5 ounces

Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3. Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4. While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp
