I have grown using 10 26=100 watt cfl's from the red and blue spectrum. The bud was small and very wispy like a cotton ball. went out and purchased a 100 watt HID which means HIGH INTENSITY the bud was more compact on her clones the next time around. HID lighting made the difference. If your afraid of high electric bills you can go with a 100 watt one from say Lowe's or Walmart. look under yard security lighting.
There is no stupid questions. Just stupid answers. Keep the lights close say around 6 inches and avoid burn and all should be well. even if you take out $ 26=100 watt bulbs the HID lighting will more them make up the difference in lighting and use the same amount of electricity. Even if you use the HID lighting in flower it should not raise the bill that much. say your electric company charges you 10 cents per KILOWATT HOUR and you are using a 100 watt HID light like mine. that means you can run 10 hours for 10 cents so my bloom room runs me about 12 cents a day times 30 days = $3.60 for a bud that's more pleasing to the eyes as it is to the wallet. I doubt a whole $ 3.60 will raise any alarms but made wife's meds increase by 2/3.
