I'll assume you're electricity costs yo 10 cents a kilowatt hour. You'd need a 1000 watt light for 20 decent sized plants. Every hour the light is on you'd be using one kilowatt. For flowering you'd be using the light 12 hours a day so 12 X $.10 = $1.20 a day. For a 30 day month $1.20 X 30 = $ 36.00 . After 2-3 months if your a good grower you'd have about 700 grams of dried bud (rough estimate). Let's say premo bud fetches $15 a gram. $15 X 700 = money trees !how much do u think it would cost for enough lighting for 20 plants?
