What's the most economical way of growing indoors including supplies??

my water is free but I'm worried about electric what you guys think I am willing to pay maybe around $150. 00 tops for an eco grow light but please suggest any advice I'm lookin at a bubbler setup now but now worried about how loud it would be to run a two output air pump and a couple fans but I heard it produces better buds all around?
