600hps/400mh

[dekab247]

I have a question about this combo light. If there are any link in regard to this please post. Here is question I had.

If penetration of light of 600 was greater than 400, and 600 has to be further away from canopy. How effect is the 400 light in this double set-up. If it needs to be closer to acheive result. Would 600 not impede that? I know 600 is good, but it almost seems bad idea to put these two together. Other than good for mixing up spectrum a litle bit. Thank you...

they combine forces when you put them together...i would definitely use a 400 and a 600 together especially with the mixed spectrums...and believe it or no i can get my 600 just as close as a 400 to the tops

Unicorn,

Thank you for your response. I was curious so I asked. The reason I am interested in this light is to throw down a lil bit of MH onto Sat dominated plants. It is that or a double 1000. The latter would take away power from other spots I want for. Again thank you...

Hey dekab-

I was also wondering a few things on these combo lights. Have you thought about how they are pitched when sold. Yours was called a 1000 watter right. Mine as a 800 watter (400hps / 400 mhl).

Are they really the same intensity as, say, a 1000 watt bulb. I mean, do you keep the bulb the same distance from the plant canapoy as a 1000 watt bulb. Since the bulbs are right next to each other, in the same reflector; wouldn't you accumulate the wattage ( as the manufacture did on the package).



Unicorn,

How close should the light be to the plants using my cpmbo 0f 400hps/ 400 mhl.
And is the suggested distance due to its lumen output, or just the radiant heat hurting the plants.

Man, I am dying to know this. Have not seen anyone talk about these SunSystem Vll fixtures. I have heard about the benifiets of using a fuller spectrum in flower. Tighter buds, slower growth, less streching.

Is all that really true.

I also have 1 sun system 400 watt combo,what a dynamite fixture.I have it alongside a 1K MH for veg,I've used it in flower also.In my opinion you cant beat the combo,if I was to start over I think it would be with all combo fixtures.The 600/400 must really kick ass,dont let the difference in wattage throw you I bet its one hell of a fixture.Take note thaqt growzilla also makes a combo but puts their lamps side by side,I dont like that.Sun system on the other hand orients their lamps end to end which is a lot better.I cant believe how cool my combo runs too,about half as hot as my 1K MH.I dont ventilate my combo.Its quite a bit larger also than standard hydrofarm fixtures,its the best for veg.The only reason I dont use it in flower is I think the vertizontal with a 4 ft octagonal hood is about the best you can do for flowering plants.The combo's are perfect for veg

well that depends on what you have as far as cooling for your light

 

[Guest]

Unicorn- Thanks for the reply. So what do you think about streching, bud tightness, slower growth. Is all that true when combining the two spectrums of light?

If heat is not an issue (venting seperate from grow), then what would you say. I mean, I think you are misunderstanding my question.

Does the two bulbs equal a greater intesity than an individual bulb (hence, thier approximation to each other under the same hood. And how the manufacture labels the product as 800 watts.

I know that you would want to be careful about the radiant heat from these. Like skelator, have used both bulbs under veg. without venting, and close to plants without issue. But what chart do I use for the distance, and will they penatrate more than a 400 watt bulb?

Thanks unicorn, for your help.



Hey Skelator- I have seen you around here quite a bit. Glad to finally talk to ya. Those german reflectors are awsome, aren't they. I am using three side by side. In fact, it was the first thing I bought. Found them for 400 a piece to include glass, bulbs, duct fittings, and shipping. Could not pass that up. What I really like, is how the ballast is seperate here, giving alot of flexability. When the plants were smaller, I had two fixtures running. One for 9 hours, then it cut off. Then the other would run for 9 hours. Penetrating the canopy from diff. angles. The ballast have yet to get warm.

I am approaching flower, like dekab247. And wondering what all she will do for me. Frmrgrl at the other forum talks alot about this set-up. just not the intenity. One could mix the ballast in the fixture to give you two hps bulbs (instead of mhl/hps combo). I want to decrease the strech of the sativa. How hot much more heat does the 1000 put out over the 800. isnt that a great light. The reflectors are hughe. So I guess a four inch fan really would cool them both off. I was worried about the heat thing. Now I feel alot better. Man this stuff really adds up.

Thanks skelator for your comments.

mh definitely makes the buds aliitle denser and limits stretch

 

[Guest]

Is it the higher lumens in a hps bulb, or is it the red in the spectrum which makes it streech ?

How far would you put the 800 watt light above the plants. Are we talkinh 5-8 inches above tops with a well ventilated area.

 

[Jam Master Jaco]

My question for this thread is which is better...a 600 hps/400 mh combo or just a single 1k watt bulb?

 

[Guest]

Full spectrum for personal.

1000watt for comercial.

 

[Guest]

skelator-

How tight are those buds under that kilo watt of metal halide ?
Got some pics ?

Thanks

From what I've understood, yea it's the red spectrum that makes the plants stretch a bit compared to other, like MH. I also came across an article 'bout using both HPS & MH lights in flowering. (An ICMAG story I guess?)
The thing that MH lights have over HPS is the UV-B light/radiation, which is the same type that is produced by the sun. The article suggested that this addition somewhat increaces the THC/trichrome production.
I have no experience in using MH lights, but I thought some of you might find this interesting.

Hey Chilly Willy

Hey Chilly Willy

First off nice to meet you, and all others that responded here. I asked this question, because all I have ever dealt with was 400/150 lights with a single spectrum.

Chilly you are right. It is marketed as a 1000. It is a 600/hps, coupled with a 400mh. I have also seen those you mentioned the 400/400 with hps, and mh. As I stated earlier. I wanted that particular one for Sat's, or Sat dominated plants. I was hoping to get some more blue/mh to them. Otherwise all the other lights in my bloom room will be 600hps. 3400 watts there, and 400mhx2 for veg and a 4 4ft fixture for lil babies to be born. Then again I will do more research, but I think for that small area in the room. I will go with a 1000mh. Like I mentioned that will be more sat/ or sat dominated plants. I am still trying to decide what light scheduale to put them on. I see some damn good results with the more varied lighting scheduale with Sat's. That would entail closing off that part of the room though if I go with a different light schedule, and if I don't have to. Or feel the need then I won't do that. Sorry to get off topic. I will try my best to answear the rest of your ?...

You asked...
^^^Are they really the same intensity as, say, a 1000 watt bulb. I mean, do you keep the bulb the same distance from the plant canapoy as a 1000 watt bulb. Since the bulbs are right next to each other, in the same reflector; wouldn't you accumulate the wattage^^^

I don't believe they would lack intensity. They should do a damn fine job. If not as good. Close to the 1000. Tho' they may benefit, and make more with the dual spectrum. Unsure of where, but I believe I read it here. Many happy with reults from their dual spectrum lights. It seems to do a swell job. If you go by the lumens per ea bulb. 600hps and 400mh. Add two of them together you get approx 140,000. A reg 1000 hps will say 145,000 give or take. Depending on the bulbs you use. Plus the added bonus you get both light spectrum's. The 600hps should let you get closer to the canopy than the 1000 will. I tho' was just worried that the 400 would not get as close as it needs to the canopy. Thus limiting it's effectiveness. Unless I can prove otherwise. I will be going with a 1000mh. Or possibly a dual 1000 hps/mh, and just backing off on some of the other lights. I hoped I helped out with an answear. Anything else I can assist. Ask here, or in Pm. Whatever you would wish. Thanks for your input here. It has given me a few ideas to look into. Stay safe...and, peace...
