I'm glad to see that people are embracing the benefits of full spectrum lighting. I have switched my rooms to dual-arcs about a year ago.
I just wish that plasma and CMH options were available in 1000 watt versions...
Why plasma or CMH at such high wattages?
I've seen definite benefits with wide spectrum phosphors such as reduced wattage, reduced heat, longer lamp life, higher quality product, etc....with the biggest drawback as intial cost to purchase. But when you compare the cost p/gram and expense lamp change outs 2x a year with both the MH and HPS plus the added HID ventilation for cooling HID which the 420's don't need then the return of that intial investments can be expensed within 1-2 harvests.
So I won't consider any single lamp @ 1000 watts unless it yields better then a gram/watt allows full veg-bud from a single lamp source and I can get a year or more out of the lamp life. Not sure about the 1000 watt dual-arc lamps for full spectrum but sulphur plasma for PAR spectrums is strictly a veg UV band lamp and they run about $1,500.00 per light.
Here are week 5 pics of the IDA White Russian, Waikiki Queen and Sugar Baby all under the 420 series.
Happy Thanksgiving to All!
