ColoradoHighGrower is right, it will greatly depend on your tents air intake and exchange. I would add to this that as long as you've got cool/cold air going into the tent a 315 would be absolutely fine.
I myself have an 8x4 with an 8" inline fan pumping in the cold night air from the outdoors. Then theres another 8" inline fan sucking it all out on the other end of the tent. Due to the heat here in Northern California I have to shut down that CMH tent from June until October every year.
@Bad Karma I am finding that when I water the plants in 8x4 the humidity jumps to 65%. There are 2 315cmh using 2/3 of the tent. The other side is just vacant. Do you filter your intake fan? The room and house are at 50% if that. Do you find the intake fan helps? I have intake fans in my 4x2 tent but not the bigger ones.

Yes, an intake fan will definitely help lower your humidity. I find it helps to run my lights overnight so I can pump in the cold night air from outside, if you can. Also, that vacant area in your tent should be for a couple of fans. Place some high, place some low, but all of them moving the air over the soil, and helping to dry it out faster, thus lowering your tents humidity.

I do run my lights at night. I added another clip fan and ordered a oscillating clip fan. I also added a lasko fan to the room and the RH in the tent is 54% during the day with the lights off. I am holding off on plugging the dehumidifier in just yet. Its day 23 of flip. Thanks @Bad Karma

Currently just running the 3100, but i tend on getting the 4k to separate out the spectra per photo-period stage.... not too bad though... so which do you prefer for both stages @DCobeen?
I said it wrong I like the 4200k over the 3100k where I have 4200k I am seeing more color coming from my plants and a bit more resin production. I am now ordering more 4200k bulbs and gonna alternate them in flower so each row of lights will be like this for flower
4200-3100-4200
3100-4200-3100
4200-3100-4200
this is a 9 x 9 grow area. I need to get 1 more 315 to make this happen and the 4200 in the middle will be a 630 DE 4200 to help overlap better. I will see how this goes(yield light coverage) and if needed the will change the 3 middle lights to 630 DE

Interesting - since the 4k is intended more for veg, i wonder if it's the higher UV with the cooler spectrum that gives better color/frost by the end of bloom? I actually looked into/tried to buy a 10k finishing bulb, just to see what it would do, but after getting two consecutive defective/broken bulbs deliverred from hydrobuilder, i gave up.. just haven't had time to look at other options yet. I'm thinking i might get the 4100k, use it for veg, swap out to the 3100k for bloom, and swap back to the 4100k for last two weeks to finish them... I also have 6 24w 24" T5s in there, with 3/3 veg/bloom bulbs for supplemental light. Ideas?

Dollar for dollar, what do you all think is the best 315 complete system to buy for just a 3x3 room? It does not have to have a dimmer, but would be preferred.

You could get a cheaper one, but it'd have a cheaper, small, horizontal setup, and attached ballast. Then you have like Nanolux that are $319 vert mount, with a MaxPar bulb, can't run a Phillips according to reviews, blows em. Has ballast attached.

Then what I got. The tried and true SunSystems Remote Vertical Reflector. Despite what I thought about verts initially, tests show you can get better par with em, and a nice uniform square footprint for the 3x3. You can put the ballast outside the tent. They go for like $150, but there are deals that pop up on eBay for $110-$120 I grabbed a non-dimmable Prism Ballast that came with the best CMH bulb according to testing, the Phillips Agro. $200. I've had no issues so far. $350 brand new unless you bargain hunt. Spend more and you could get a Phantom or Gallaxy with the bells and whistles and still keep it external. There's my 2 cents :eyesmoke:

I have grown start to finish many plants under my 4200k 400 cmh and I like that spectrum. I also had 4k bulbs in my 12 bulb t5 right next to the cmh and both did great jobs. Using actinic and coral plus bulbs in my t5 added even more color and frost with allot more resin production. If you look at the spectrum of the 3100 and 4200 bulbs you will see you a bit of UV but gain in photosynthesis.
That is why I am mixing the 2. Here is a test showing diff lights for 315 cmh bulbs and the uv output.

It's all about your budget. @Underground Scientist is right on about the hood. I have shorter celling's so I went with cheap complete units and so far I am happy with them. You can find complete 315 lights with hood and bulb for $150 or can spend $450 its all about what you can afford. I went cheap as I have 8 of them and 2 630 DE units and still need to buy 1 more 630 and 3 more 315 lights so I can have a spare 315 as I really don't trust the cheap ones and a spare unit is a good thing.

So if not a sunsystem unit what else would you recommend? What has the bells and whistles?

I want to get a 315 again for my 3x3 and I'm debating whether to cheap out on the socket adapter prism ballast and Phillips bulb and run it in my Daystar a/c hood or to buy something new. Anyone mess with the DE 315's?

I know that my 630 DE puts out as much heat as my 1000 watt HPS bulbs did and just as much par so read reviews about the 315 DE as far as heat and par to see if its worth it.

Did u just say Socket Adapter...Michigan Med Grower will be jumping out at you over the loss in efficiency with that...lol

A good dimmable ballast is supposed to be the Galaxy. Check Growers House website. Don't quote me, but I think the phantom hood you can draw heat from, and a phantom is similar in price to sun systems.
