Hey guys was wanting to know how to get an estimate of how much it would cost me to run one 400 watt hps thanks!
I’ll be growing an auto so it’ll be on 18-6 light schedule
So probably roughly any where from 30-75$ to run per month
Damn! Now I see why majority go with led. lol thanks for advice✌🏻️ @Majiktoker
It depend on how much is the rate by kilowatt/hour that charge your local electricity distributor , it will be shown on your electricity bill @Swan1234
Ok I’ll have to look inTo that.️
No problem @Niala thanks I shoulda thought about kilowatt/hour
The formula is : Number of hours of utilisation × Number of days ×( Number of watts have your lights ÷1000 in your case 0.4). That’s gone a give you how much kilowatt your lamp consum, for 30 days on a 18/6 schedule it’s 216 kilowatt multiply by rate from your local electricity distributor and “voilà” you gone a know how much it will cost you approximately.
Hoping that’s helping you, @Swan1234
Thank you!️ @Niala
This is just a basic way to know… had an old-school grower tell me this.
The first numbers in the size of your bulb generally will tell you what it’s going to cost you.
100 - $10
250 - $25
400 - $40
600 - $60
1000 - $100
1200 - $120
And that is very, very close, my 400 watt HPS, cost me around $40 a month to run.
