How many Grow lights do I need ?

[ambitiousrj]

I’m growing in a 64x30 ft space using the Growers choice 315 watt grow lights which pulls 120-240volts and covers 3x3 space how many grow lights will I need to fill the space and how many watts would it pull from the electricity?

About 20 with the light you would use
The spread being only a 9sqft ratio
And about 60amps 120v id do 5lights to a 15-amp breaker and break up the load .
Also take into account , fans, dehumidifier, heating and cooling and other accessories you will add depending on grow media.
Brace for additional 40amp load.

Now if u did 220v on lights u can cut that load down by 3/4 so going higher voltage is an advantage.
