I have never grown under fluorescent bulbs and I have a few questions. I have found a T5 setup for sale for $60. My first question is, is that a good price for a used 4 foot 6 bulb set up? I'm having trouble finding used prices and I know that it is good compared to new. I already own a HID setup and might be upgrading that as well a little further down the road but I was considering purchasing this for mothers and a few autos. My second question is, would I be able to take one bulb to test it and check each individual spot or would it need all 6 bulb slots filled to fire up? Are there any questions I need to ask the seller? Are some brands more reputable than others? Any help or advice regarding this would be greatly appreciated.
