A typical grow is closer to 3 months. Most veg for about a month with part being 24 hrs then an 18/6 week or 2, followed by 8 to 15 weeks of flower on 12/12. The bulbs will last longer but the output starts to degrade the second it's turned on. The quality of the bulb plays a large part as well.

Bulbs should be replaced every 2 grows on average, I've heard of ballasts lasting 5+ years, I retired mine after 2.

None of those pictured are bulb, fixture, and ballast. To get a full 1000 watt HPS setup, I.e. bulb, fixture, and ballast is going to cost you almost $200. Most growers will also need some way to cool these lights, exhaust fan and ducting will come to another $60 to $100 depending on supplier...

The fact you're in a 30' x 20' room gives you alot more room to dissipate heat, most people don't have that luxury. I know if I had that much room my grow would be alot larger. You can't be using that entire space with just 2 1000's though. Imagine how much heat you would have with that room at...

With a hydro system, no soil at all, 4 1000 watt hps, the. additional fans needed for them, and increased AC use the power went up over $350. The same grow under LEDs uses 423 less watts per light, no additional fan just to help cool the lights, and not only not having to run the AC extra but...

The purpose behind LEDs is lower heat emissions and lower watts pulled by the lights. With a decent light they will pay for themselves in the first harvest in power savings. And how do you figure 35 plants under 1 1000 watt HPS?
