Reasonable HPS setup

[DaHui]

Tronix, what are you using for ventilation and how hot is that 430w?

Also why are the 430w hps cheaper then the 400w? can you use a 400w bulb on it anyways?

sorry Dahui didn't see your two question till now, my bad..
For ventillation, I use two computer server fans, mounted directly into the cieling blowing into the attic space..my temps stay between 80 and 95 degrees..remember MJ is a tropical plant, it grows best in nature nearest to the equator..so hot isn't bad, so long as it isn't too dry.

and the 430 watt is slightly more efficient than the 400 watt, I dont really know why. (hence the lower temps)
And I believe you can run a 400 watt lamp off a 430watt ballast..the 430watt lamp is more expensive (between $60 and $75 ea..) but they last for over a year so that isn't too bad..

How many plants could you flower with the 430w? Could you use it for more if you had a light mover? I was always curious of these lights. do they have a 600w Son-agros or only the 430w

With a light mover it depends on how big area is the light moves within..but theoretically one or two lights could do several plants..
I have never heard of another size of Son-agro, but I'm not sure about it..I'll do some research and get back to you...
