In using 2x cmh to replace 1x 600 am I wrong in thinking this. With two cmh ballasts and more surface area to vent heat into the air>duct>out would that mean the ballasts combined are going to run cooler ambient than a 600 ballast?.
What are your plants telling you compared to what they told you while basking under a single 600 watter?

3 rows with seven 315W CMH each. You'll have room for 2 aisles about 50cm wide.
@ttystikk @Bad Karma @since1991 @DemonTrich @GroErr Has anyone used this for a 12/12 room? The spec sheet on my phantom 315cmh says 1.5amp draw so four lights with my fans on 24hr this is way under my 30 amps allowable draw and I can cover only a 6' x 6' area? I have the phantom 315cmh ballast because it is a remote ballast. Are there better units that are also remote ballast? Screen Shot 2017-09-26 at 9.01.06 AM.png

I know a buddy that has that same exact 4 lamp relay box. Extremely well built but expensive for what it actually is. You can get other switch boxes with trigger cord for the timer (I would go with a seperate timer - not one built in) for ALOT cheaper. And its preference but I like to hard wire my line from the fuse panel to the relay box. With those you have to wire a plug recepticle outlet to the line then plug the box into the recepticle. More work...more money. There are even instructions online on how to build your own relay switch box for really cheap. But those are nice. The extra outlets are cool for other accesories that need to be on when you set the timer.

X2 on just scoring a light controller for much cheaper.

Also the built.in timeer boxes. If the timer fails, the unit is worthless.

I use this light controller as a power supply for my ac, and use the trigger cord plugged into my greenhouse controller as the on/off source.
@DemonTrich would you mind PM me a little more info on how that controls the lights and the environment. Is your a/c on the thermostat controller?
 
t9 designates single wall glass tube and t12 designates double wall glass tube
Thanks for that.Seems im using a t9 in an open hood.I talked to the store and they assured me it was perfectly fine and they had sold hundreds etc etc.I then read the 450 lec grow in colorado and hes in open as well.I'm loving the light but im a bit confused as to the risk? Is it any more than a metal halide for instance?
