I have the one your looking at and a 4 lamp T-5HO, I like the T-5 a lot. The bulb replacements for the first are like $70, T-5 are like $8 a peace. This is what I use http://www.amazon.com/EnviroGro-4Ft-Tube-Fixture-Bulbs-FLT44/dp/B005H1C7NA/ref=sr_1_3?ie=UTF8&qid=1397239752&sr=8-3&keywords=t5+grow+lights

I have a 4' Hydrofarm grow light for seed starting. Last year we just had a single tube and pair of LED strip lights for seed starting. That worked, but this year's seeds were significantly better.if you wanted an actual indoor garden you would probably need more light than what I have now with a total of 5 T5HO bulbs and LED strips. Last year we still had to buy a few seedlings for the garden, but this year we haven't had to buy any.
