How to use UVB with LED grow lights

Why use UV in the grow room? Read more here: https://migrolight.com/blogs/grow-lig... Shop MIGRO UVB (global shipping): https://migrolight.com/collections/uv... I demonstrate how to setup the MIGRO UVB grow light with an LED bar light, the ARAY 8 PRO in a 4ft x 4ft (1.2m x 1.2m) grow tent. SAFETY: Do not stay close to the UVB fixture (less than 3ft or 1m) for more than 5 minutes. As with sunlight prolonged exposure will burn the skin and damage your eyes. There is not UVC output by the fixture. The 2ft or 60cm ARAY UVB is 20W output and will cover up to 5ft x 5ft or 1.5m x 1.5m The UVB fixture should be hung at 2ft or 60cm above the plants canopy. This is 40cm or 16" above the LED bar light. The LED bar light surface ares is less than 20% of the canopy area so 80% of the UVB photons pass the bar light and reach the plant canopy. In this setup there is a range of 150 µwatts/cm² in the centre to 50 µwatts/cm² at the edges and an average of about 100 µwatts/cm² over the plant canopy. This is less sunlight mid-day sunshine in summer which would range from about 130 µwatts/cm² to 180 µwatts/cm². #uvbgrowlight #growlight #migrolight Follow us: Instagram:  / migrolight   Facebook:   / migrolight   TikTok:   / migrolight
