How far should 250W HPS be from plant?
For 250W HPS, the distance of the lights from seedlings has to be between 10 inches (25.4 cm) and 14 inches (35.56 cm) from your plants. Place your hand where the seedlings are for about 30 seconds. If the light is too hot for you, that means it’s also too hot for your plants.
Will HPS work for veg?
In response to the general question, can you use an HPS bulb for veg, the answer is yes.
How high should I hang my HPS light?
Hanging Lights Too High While a 24-30 inch mounting height may be typical for HPS/CMH lights, this is an improper mounting height for LED grow lights. VOLT Grow® LED grow lights are designed to be mounted between 6-12 inches from the canopy for maximum yields.
How much heat do HPS lights produce?
If you have a 600 Watt HPS lamp, the BTUs for that luminaire are the same as a 600 Watt LED. A single watt of power is equal to 3.41 BTUs so a 600W luminaire will produce 2,046 BTUs.
How high should my HPS light be?
HPS lights should not be placed inches from the plants, as you would place fluorescent lights; you should set HPS lamps higher, generally between 5 and 8 feet from the plants. Whether you have a reflector with your HPS light makes a difference for how close you can keep it from the plants.
Do you need a ballast for HPS lights?
HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.
How many watts veg stage?
Veg Room Set Up A good rule of thumb is that between 10-20% of your total light wattage in the Flower Room will be used in vegetative growth. This means that if there are 50,000 watts in the Flower Room, there should be between 5,000 and 10,000 watts in the Veg Room.
What’s better MH or HPS?
MH lamps provide a more natural appearance in color and are typically the choice for plants that have little to no natural light available. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.
