Grow Light Frequently Asked Questions

What is the difference between Metal Halide and High Pressure Sodium and which one should I buy?

Metal Halide bulbs produce a bluish white light. It produces plant growth. High Pressure Sodium bulbs produce a yellow/orange light. This light, heavy in the red spectrum, promotes flowering/budding. Many growers start their plants with Metal Halide and then switch over to High Pressure Sodium for flowering mazimizing the best of both bulb types. Other people use just one bulb type for the entire growing cycle depending on the type of plants being grown.

How much electricity will these lamps use and how much will I save if I use the 240 Volt option?

Wattage=Amps * Volts : A 1000W lamp is going to use the same wattage at 120V or 240V. The amps will be different but the electricity bill is based on Wattage. Therefore, there is no electricity bill savings using 120V or 240V.

Cost for Electicity=(hours light is on)*(Wattage of lamp) *(Utility rate charge $/KWH)*(1/1000)
Example:
$1.32/day=(12 Hrs/Day)*(1000 Watts)*($.11/KWH)*(1/1000)
