So I had a thought today as I was pondering the needs of the plant during flower. When is the higher wattage most effective during flower??? ie... If I had two lights, one 400w and one 600w, would it make more sense to flower under the 600w for the first 4 weeks and finish with the 400w or start with the 400 and finish under the 600? I have searched but all I seem to find is light distance to plant or wattage per area or number of plants, but nothing about the beginning and ending wattage for a plant during flower. Thanks for your input GC.
