Verticle bare bulb cmh

Right, thnx. Theirs little to no worry on turning the actual hood fitting vert I take it.

The hood itself is just sheetmetal and maybe a piece of glass; it doesn't care. Some hoods have gravity heat vents- they're on top because heat rises- but if you remove the glass it shouldn't matter.

All helpful, thnx again.

Hopefully my quote is pertinent to the topic, I run 2 bulbs 600w each hanging vert, hoodless , hps + mh spectrum along. An old school grower told me that as a tip for a set up and I don't see any thing wrong w that and I had to hang the bulbs w a vertical mogul socket w a 25 ft long cord so I could keep the ballasts out of the room and made sure to get vertical bulbs as well.
Does the combo w led + hids result in better yields ? View attachment 3688386

Which 600W MH are you running?

Hortilux Blue 600W horizontal (recommended) still running strong vertically

High One,
I's running both spectrum w a 600w mh digilux along a 600w hps powermax 18/6. I flipped yesterday 12/12 and start w 2x 600w hps (Powermax & Ushio opti-red) 2 vert bulbs . I picked vertical bulbs due my low budget at that time, and later , I also heard that the hoods could hold a serious heat in the grow room even more than a bare bulb, so that wasn't a option for me cuss my garden is in a attic, yeah some people say it is daunting or impossible, well I insulated the walls, put a ac unit , a fan and created an exit and an entrance for air from out side. It is dry as a desert most of the times, windy and I'm a 28ft high above the street, away from eyes and noses.

My plants responded better to the 315W CMH lights than they did to 600W HPS.

r these CMH bulbs 4 magnetic ballasts?

No. Run them on the square wave ballast for best results.

Can you provide an example of one?

For a 3x3 tent would I get by well with one 315 CMH run bare or would (2) 315's be better, or something else completely?

My current CMH is the Sunsystems 315w LEC running the phillips bulb

How you going to deal with heat running two in a 3x3?

I'd say one would be more than enough.

Badass ballast, discontinued
Horti Platinum ballast, out of production
Revolution Micro integrated fixture
Sunplix is rumored to be coming out with one.

One 315W per 3x3 is right about the recommended density.

My ceramic science ballast has been solid however I believe phantom also makes a square wave. If you hang them bare heat won't be as big of a limiting factor as one would think.

So then for right now I'm SOL lol.....

He isn't gonna want a philps 860 in a 3x3.

I think 2 315's spaced to give the vertical coverage desired would be doable

You think (2) 315 hung vertically bare bulb is too much?

In a 3x3, yes, unless you can deal to the heat. I have a 600w mh in mine horizontally, but that's in a cooltube.

If properly exchanged every 30 seconds no problem.. vertical is a completely different heat signature.

Even one would be fine. I was answering two different questions.

Heat? I would say a 315w lec/cmh puts out the same heat as a standard 100w incandescent lamp, maybe less.
The ballast is another story....

My ballasts don't run too hot to touch.

What are you runnin(brand)? I'm running just the advanced ballasts wired to vert lamps.I'm guessing yours are wired @315w and not the lower 200 and something setting?? I'm running 2 sets of 4 & 4 in fan cooled enclosures and the heat pumping out is at least 140 deg....never touched it, learnt that the hard way but the lamp I just couldn't control myself. Lol
