FAQ about 600 Watts Grow Light

How many plants you can put under a 600 watt grow light?

There is no one rule written in stone for this one – it all depends what stage you plants in and other factors. If you are into bud you may have a bunch of plants under a single 600, if your plants in veg. you may have 16 plants under a 600.

In a normal scenario if you are growing marijuana for example, 4-6 plants are good enough under a 600 watt LED light. You will get a better yield. Tent size also affects the number of plants you can put in.

How much grow area 600 watt LED can cover (coverage)?

Lighting requirement normally calculates based on the desired wattage needed per square foot.

It also needs to know the particular plant’s light intensity requirements based on these factors you can determine the coverage a grow light can cover, in this example a 600w light.

It varies based on your individual needs. For example if you growing lettuce or similar plants, that have lower light requirements, use a calculation of 20-30W per square foot space.

A 600w lighting system would provide coverage for a 17-33 square foot area.

If you are growing tomatoes, you should calculate 40W per square foot. In this case, a 600w lighting system would cover 15-17 square feet.

How much does a 600 watt HPS light cost to run?

In a simple and easy to understand term – 600 watts light will burn up 600 watts power.

But in a more detail term you have to do some calculation to find how much electricity a 600w HPS uses.

In the USA an electricity company would normally charged based on the Kilowatt per hour electricity used by a consumer.

So if we do calculation based on our scenario here is what we come up with.

If a consumer uses 600w HPS for an hour s/he will be charged for 0.6 kilowatt per hour. In a normal scenario you will be going to use 8-12 hours a day. That mean:

If you use 8 hours a day then 8 x 30 x 0.6 = 144 kilowatt electricity

Multiply 144 whatever kilowatt/hour charges your city/state cost you, and you will get the total costing of a 600w HPS for a month.
