Is a 600w LED lamp full spectrum (with veg/bloom switch) power consumption 300W in the vegetative phase and 300w in the flowering phase, or always 600 watts?
You'll want both switches on. You might also want to look at supplementing the 'full-spectrum' since Viparspectra isn't actually 'full spectrum." The blurple grows rather leafy cannabis flowers in comparison to the new white light LED setups.
You're in the right place, this forum has all the information you need.
