Any suggestions as to if my exhaust should stay center, or towards an end. Air flow left to right. Lamp definately fills her up! Lots of cable, wire, rope etc to configure and secure. Still 2 clip ons to go in as well. Beast of a light. I think ive mentioned that. 
I can slide exhaust front to back if needed as well
Is that supposed to be no closer than 15” maybe?
If that’s the case, that nothing at all should be within 15" above light, I would have a problem.
Recommend mounting height from the “ceiling” is based on air flow to keep the fixture cool… you can close that gap. I recommend installing a clip fan directed at the light
@dbrn32 i cant seem to get any other rough insight by others using the 350r, as to %watts and height above plant per stage of plants. any suggestions at all. even googled and no experiences came up.
Hlg gave me a general, but would like some possible input from anyone else who had either used or knows of others who have.
I have my chilled tech set at about 30” and I have her plugged into my killawatt meter so I can see my watts and she’s sitting around 130 watts. She started to stretch when I had it at like 3 feet and 100 watts so lowered and turned up a little
Wish I could help but my light is smaller (lamp envy) and my stupid seed won’t germ so my light is sitting unused still
What kind of meter can I get to read output?
Not funny but way you say that…stupid seed one of mine that popped yesterday, still has seed shell stuck to it. Im not touching it though. Nature fix it.
I’m wondering if it’s just too cool in the house for seed to pop, I’m gonna put on windowsill or outside see if I can get that bugger to come to life
How long it been? Mine 3 days and popped.
The plants in solo cup? I would run about half power probably 2’ above canopy then just kinda see how things go.
I meant throughout the grow. Most lamps give a suggested per growth stage. This one does not.
Killawatt meter on amazon
Yeah you want the Killawatt meter to measure the lights power draw. Set up is looking great though man! Glad you are getting set up right.
Hlg recommends keeping between 15" and 24". Larger space you are in the higher will need to be in order to have light coverage equal to the space.
Depending on conditions the space and particular plants, they may be more or less sensitive to stronger light intensity. So giving you predetermined guidance isn’t always going to give you the best results.
I’m still at the 2 day stage so I’ve not given up just yet 
4 or 5 Days is normal so…
