Hence, the total light power required for a 4×4 grow tent space is near around 800-1200w. You can source that from one 1000w light or a couple of 600w lights. Many growers can say that one 600w light at a close height can be good. But merely a 600w light is not sufficient unless you're growing in a 3×4(or smaller tent).Let us understand some of the LED lights.
ECO Farm GL 800W Samsung 281B PRO Chips LED Grow Light
ECO Farm GL series light with Samsung LM281B+ Pro； 640W has 2808 LEDs,800W has 3744 LEDs,1000W has 4680 LEDs; Which can achieve as high as 2.9 umol/J of energy efficiency, so that it provides the powerful light output and uniform canopy penetration to achieve high yield. The full-spectrum grow light from 3000K+5000k+660nm+ir 730nm+UV 395nm is infinitely close to sunlight, providing a complete natural spectrum, speeding up the growth and flowering time of plants, achieving higher yield, and being suitable for the growth of plants at all stages.
