    LED COB grow light question

    I have a 4'x4' grow tent and a 1200 watt output power LED COB grow light. Is that light sufficient for that size tent? I have six GCS in about the fourth week of flowering (in cloth 5gal pots using FFOF soil). I keep the light about 2 ft above the plants. The plants all seem to be growing towards the center of the tent where the light hangs and it makes me think this isn't enough light.

    Is it actual draw 1200w or 1200w equivalent?

      Thats very important to know.

      Also, does the company provide a chart for PAR? Does it list any info about PAR, PPFD or umol/j? Most companies will provide that as well as a recommended size of tent for both veg and flower. Do you see that info on their website?

        I have a COB 1200 watts, probably 350 actual. I have a 32" sq. tent and it works just great. However your tent is much larger so you may need a second light. As to growing toward the center, al plants do this. I rotate my pots every day so that all sides of the plant can receive the direct light.
