right a 35 watt saving x8 is a 280 watt savings . so that is 45 dollar saving a month to me . its .16 per kilowatt here . 45 bucks pays my cable bill .
It's .15/18/21 a KWH here
. Then they add delivery, debt repayment, etc. So my last bill for June was $248, $100 for delivery, $100 for debt repayment (their debt repayment not mine, it's on everyone's bill), taxes as well, my total usage was like $43.00. So yup any cost savings is a bonus. Also I have tried just T5's and while it grew ok plants the yield and structure was sub par compared to my hps/Mh, could very well be my skills indoors or lack of lol.
