Update on my 630w cmh. FIRE!

I'm kidding. I love this thing as always. But, I have noticed there's a hell of a hot spot in the middle 4 square feet of my 5x5 tent. I have the standard 315 hood with the dual bulb setup. I'm thinking of cutting along the seems of the aluminum hood (drastic?) To open up the footprint a bit. Think itll help with hot spot as well. The coverage on the floor looked pretty good at 4x4 without the tent. But having to keep the light a minimum of 28 inches from plants is about to cause ceiling issues. Its pulled to the ceiling at almost 7ft and I'm only a week into 12/12 flip. Got 3ft between light and canopy but they havent taken off into stretch.
So what do you think of cutting the seems on the hood to open the footprint and allowing me to put light a bit closer?

I like the reflectors on the sunsystem 315's. Mine is vivosun. Figured for the price and the versatility of running one or both bulbs at the same time.....I was sold. Loving it, but kept seeing different charts showing conflicting area coverage for different wattage. one said a 315 light would be great for a 4x4, yet another said it was good for only 3x3. So I popped in second bulb, both at 4200k, and it seems to be going fairly well for the most part.

Let me know how it goes if you do cut those seams open and spread it out.
I've thought about doing it with my 630. I'm not real happy with it though tbh, if I could go back I would have put my money on either more of the the sun system 315s or COBS.
My 630 is a double ended bulb, both bulb and fixture are growers choice brand. My beef is that the footprint is real small, maybe 3x4 and puts off some serious heat. It almost has to be kept atleast 30" from canopy because of heat and to get max spread but at that point it causes the plants to get fairly stretchy. Its honestly a light that I dont like to grow with, wish I could sell it. MSRP was something like $450 :roll:

Ouch. Must not be in the US? I got mine for 220 with free shipping. Ah! But I DID pay 90$ for each of the bulbs separately because I didn't trust having expensive bulbs mailed.i guess it's about the same then.

Australia has a company that has an amazing hood similar to the raptor xxl I see for ho s setup. If I can find the link I'll post it. Pretty sure I can Frankenstein something seriously awesome with it.

LOoks like what I did to my reflector today. Lol
What do you think? I got the temps down enough at the canopy to lower the fixture about 4 inches from where I had it with this . Light footprint definitely seems bigger also.

No I'm in the US. The double ended bulb setup was pricier than the 2 single 315 setup, plus it was a year or maybe little longer ago when ofcoarse prices were jacked up because it was a newer thing

I now run a mixture of sun system 315s and cobs, in a checkered pattern and I'm real happy with how its treated me

Sounds pretty nice. I like my cmh lamp, but I would like to have had just a little more red spectrum. Debating swapping one bulb out for 3100k. One of each would be pretty nice, but I'm working on other issues right now. Seems more important to make sure dumbasses watching my plants actually feed them anything. I'd be happy with even just water at this point

All you guys using 315cmh bulbs or multiples of, does anyone know what a burnt out bulb looks like?

I lent mine to a mate for the last year, don't even think he plugged it in til last week, then he said it tripped the electrics.
So I took it back to take a look.
Just tried firing it up and it does nothing.
The ballast has a slight noise , like ballasts do, it then clicks every 5-10 seconds like its trying to fire up.

The bulb now has a green/grey tinge to the globe bit in the middle.
I just want to know what a burnt out bulb looks like so I can determine if its the bulb or ballast.
For all I know its been thrown around in transit or he could of half screwed the bulb in or something.
Im hoping its just the bulb. Its a Philips.

If you're sure you're using the correct ballast, I'd guess it would have to be the bulb. Make sure prongs are clean on the bulb. My bulb has a greenish hue to it. You're sure he gave you the correct bulb back? Take it to a hydro shop and they can tell you. I haven't seen my bulbs with the power off since I got them to be honest, but it doesn't sound like a blown bulb.

Hello fellow CMH growers, I suppose I am going to add myself to the CMH club since I just got my first LEC fixture just a couple weeks ago! :) I was wondering if any of you all had issues with cal/mag deficiencies since moving your plants under CMH lights? I love my CMH so much, I just can't seem to get this calcium deficiency under control and it only started once I moved my autoflowers out from under their 1000w HPS and into my 315W CMH tent. Anyone else had this issue? I'm assuming it's from the more widely available spectrum and increased UV?

I’m about to join the club...chose over qb and cobs.. price being the main reason..
I’m upgrading from blurples.. my ? is what’s the advantage of hood vs hood less. Are some of the lesser valued 315’s just as good?

For me in coco, veg or flower, under cmh. Starting with 80% ro, 20% tap.
Where others, using the same medium/nutes, did not require additional calmag......I was forced to supplement to recover them. Used calimagic @ 4ml a gallon every watering. (I had pre-buffered the coco too)

I swooped a pair of these on sale...free shipping. 3yr warranty on ballast. Philips. Remote ballast. Yet to see better bang.
