Dual Bulb hoods

I was wondering if anyone has tried using one of those dual bulb hoods using 600 watt metal halide in one socket and 600 watt high pressure sodium in the other for the duration of the grow opposed to a single 1000 metal halide for veg and changing to 1000 watt high pressure sodium for flower and what the results were.

Thanks

just get a ceramic metal halide if you dont want to switch bulbs

Yeah i understand that ceramic is defenitly the way to go and if there was a 600 watt ceramic I would jump on it, I was just wondering if anyone has used the dual bulb hoods and if the diffrence is worth the extra cash....

Aparently no one in the forum has tried using both types of bulbs in a dual bulb hood, or dosent think that the results were worth posting. Please let me know if you have tried this and if it worth the money..

Naw, get one of the new dual arc bulbs and save yourself the hassle of two lamps in the same fixture.

People who don't understand the question shouldn't answer it.

Yes. Using both throughout the grow would be superior to using one or the other.

People that don't understand a response shouldn't post snarky responses.

A dual arc bulb WOULD be using both throughout the grow, just not in seperate lamps and the hassle of a fixture requiring two lamps and two ballasts!

That still wasn't answering the question.

Dual arc bulbs have a terrible PAR rating and are, until the technology is improved, vastly inferior to either technology individually implemented. Recommend inferior single bulb solutions when CMH bulbs are now readily available for both MH and HPS ballasts is also a tad silly imo.

I apologize for the attitude in my initial response though. It was uncalled for.

i have seen these on the market like the "
[FONT=Arial, Helvetica, sans-serif]Growzilla Dual Bulb Air Coolable Reflector[/FONT]


i believe they also have the air cool tubes . i would also like to know if these are any good. You would be giving all your plants both spectrum of light, benefiting from both bulbs at the same time with out an extra lamp or needing to change them. i think you still need to ballast for this one hood.

Sorry, I have not seen data showing poor PAR in either the Ushio or Hortilux dual arc lamps. Are you sure you are talking about the same one I am? http://www.growlightexpress.com/hps-mh-bulbs-7/dual-arc-hps-and-mh-68/ushio-1000-watt-dual-core-tube-lamp-887.html

If you are, please link to any info regarding poor PAR performance, that would be greatly appreciated. I heard about these on ICmag forums and they sounded great.

I heard good things about CMH but I didn't think they came any bigger than 400w. If they do, then I apologize, that's just me not keeping up with the latest/greatest.

Here is a pic of my DIY combo hood. 600HPS and 400MH. I use just the MH for the first 2 or 3 weeks of veg. Then add the HPS a week or so before transition. Then both up until the last 2 weeks or so before harvest. Those last few weeks I add a HPS on the MH side. I use Lumatek ballasts. I like the results. I think the blue spectrum especially helps control some of the vertical growth during the transition.

Thought I better add a pic of the results so I do not get yelled at!!!!! LOL IMHO I think anyway you can have more of both spectrums, more natural like the sun, you cant go wrong. I know I am enjoying experimenting with it. And love the results!:weed:

I Recently tried the dual socket hoods and it was actually pretty nice other than buying two very expensive bulbs. I found heat was a bit of an issue considering you have two bulbs worth of heat.

Thank you cowboylogic. I was just wondering if anyone had done exactly what you have sown. I like the results, would you say its worth the extra cost?

Your welcome. And yes I do. 400 watt mh bulbs are much cheaper than a 600 watt hps to mh conversion bulbs, use less power than the 600 and produces about the same lumen output. If they made an actuall 600mh then I would use 2-600. But since they do not I will stick with my 600/400 combo.:shock:
