So Im planning out a larger grow room where Ill be using 4 X 600W & Ive been going back & forth on the cost of electricity for only the HPS lights. I understand that the primary factor would depend on the electricity supplier so Id like to ask the UK growers what is the approximate cost for your HPS lights?
Please state the number of lights the cost is calculated on, the wattage of each bulb & duration in months or quarterly etc.
