GrowCNanswered grow question 3 years ago I do not know what lighting you have now but yes, I would look at additional power. I have white LED's and like the power to provide 375 watts per meter (35 watts per square foot), and I consider 320 watts per meter (30 watts per foot) a minimum. You can turn down the power or raise the light when sprouting and during veg. Then crank up the power during flower for maximum yield.
