To add a little more. Only if you are running a extreamly large opperation or a commercial greenhouse would it justify the cost.

then you state save me $750.00. IT COSTS $900.00. I don't see any savings. There is no energy savings unless you are billed by demand and usage as far as I know only commercial buildings are billed that way not residential.

The other thing is that it is a very well worded sales pitch to get you to buy something for $900.00 where as if it sold for $250.00 they would still make a good proffit. IMO.
