It's okay everyone, the world goes around on people like Ronjohn. He's the type that buys by the 1/8th, buys a pack of smokes 1 at a time, never heard of costco, and has no plans for 6 months down the road. The economy depends on some level of shortsidedness amongst a section of consumers so please remember, arguing with fools only proves there are two. I am sensitive to the fact that I may be trying to justify a "large" investment so I wanted to jot down some of the numbers again and show reasoning.
HID 1-1000W:
Startup: Hood, ballast, 2 bulbs, 25 feet of duct, and a 6" fan cost me about $525. I'm sure I could have got this down to half that price if I had been patient with CL or something.
To keep running: my energy bill was $220 a month in bloom, $240 a month in veg. It is now $160 a month flat it seems so I'm saving $60-$80 in energy per month. Reductions in consumption were REMOVAL of my AC unit, 2-400W lamps versus 1-1000W and that 6" exhaust fan no longer needs to be running.
Bulb replacement: I estimate it at $75-$100 every year or so as mostly I'll just be replacing the one HPS bulb (I SOG short veg) versus no bulb change for 6+ years (warrantied for 10) with my new induction lamps.
Induction startup: 2-400W cost me about $1400
$1400 versus $525 means I spent another $875. I'm saving $60-$80 per month in energy or $720-$960 per year. I'm saving $75-$100 in bulbs a year.
Therefore I'm saving anywhere from $795-$1060 per year using 2-400W induction lamps versus 1-1000W HPS, but it cost me essentially $875 to get those savings.
Assuming we're both growing in 5 years time you'll have spent an extra $3900-$5200 with you're 1-1000W versus my 2-400W. Think about how this changes if you were running 6-1000W HPS and went to 10-400W induction?
Again, I appreciate your skepticism but math doesn't have a stake in this game.
