I am growing one plant of OG KUSH AUTO strain from Nirvana with light setup of 200watt of white led flood light and 300watt of led grow light. Is this much light enough for a single plant?
I am using soil as grow medium.
That 300W LED is more than enough for one plant as long as it's TRUE power draw is 300W. I don't know what the wavelengths are on your floodlight, but it might not even have usable light for photosynthesis. You may risk burning them without benefit.
