Overdrive newer HPS bulbs to match best LEDs?

Running nice 4 QB's 600 and 1 Crecer PanthrX. May be moving to few big plants with higher ceilings.

We have two mega huge XXXXL - huge. The biggest I have seen and can do 5x5 easily. Keeping all the LEDs. LEDs are it.

I had heard there were new SE HPS bulbs that were like 150,000 lumens where the regular ones are about 105,000. Using one or two XXXXL fixtures in the winter with the other LEDs can work. The heat can help at night in the middle of winter even with CO2 propane running.

Anyone know about these new technology HPS bulbs?

Those hoods are ok but just know that the light is so diffuse those hoods are best used for scrog with a canopy no more than a 6 inches thick. I used them for a long time and they do alright but because of the diffuse light you'll yield less per sq ft.

Your 5x5 will yield the same as a 4x4 under a differant hood if that makes more sence worded differantly.

Not to disregard your experience and anecdote, but the more diffuse the light is, the further into the canopy it can penetrate.

So your saying if you use that in a 10x10 it will work just as good. That's not how it works diffused light does penetrate better but if you are using less watts per square foot you lose those benefits

That's not what I meant lol.

Obviously PPF is relative to the space, which equals the PPFD. I was just saying how the extra diffusion would mean your canopy could be thicker. Those magnum xxxls fit in 4x4s and kick ass

Well go ahead an get some an lemme know how it goes. I've ran every type of hood I've ever head of.

It's not that I dont like these hoods, I do. But the same yield can be had in a smaller space with other hoods.

What these hoods do give is a nice extremely uniform bud shape and size over a 5x5 but it's not more than another 1k hps in a 4x4.

There is however a learning curve to using them as in practice the buds 6 ish inches down dont get any light at all and dont develope.

Sorry to argue with what you belive but over the years my results were pretty obvious to me...
I've ran parabolic, batwings, multilight reflectors, really you name it I've prolly ran it.

I understand what you're saying, i just wanted to put that out there as general information. I believe you can definitely use a smaller hood in a 4x4 and get the same yield, but in a 5x5 it will use the entire space much better if that's what you desire, but like you said your yield per sq ft would be lower (but the yield will be about the same). When you run a smaller hood, it covers more like a 4x4 so you get big buds in the middle and larfy ones on the edges.

Personally if you're running HPS in a 5x5 i would look into air cooled double ended hps or just run 2x 600w in magnums.

Exactly. I ran a xxxl in a 5x5 for many many cycles, so I understand it. There is a benifit to it.
It's just not going to be "more"

Currently running a de hps 1kw over a 5x5 though, differant shape hood, covers the same area, better yield. So I'm happier where I am now. But it's been less than a year since I was running the xxxl hoods.

I can say for scrog I'd take that style hood over others if running scrog and not running de hps

Some actual hands on info from another forum member -
I tried the "Par Pro hyper-arc" lamp from sunlight supply. Basically a DE arc tube in an SE lamp. I would not recommend them....
I purchased two of them. Admittedly I ran them dimmed to 600W - then 750, 1000, etc to ramp them up as the weeks went on.
One started randomly having problems igniting within about a month. Swapped back and forth on multiple ballasts and narrowed it down to that lamp.
The spectrum also seems a bit whack when compared to the Hortilux Super HPS (which is what I went back to).
I belive USHIO has a Mega 1000W SE HPS lamp as well and I would definitely give that a go based on the quality I have seen in other USHIO lamps I have in the garden.
I run raptors as well and you can definitely cover a 5x5 with one.
So my recommendation would be Hortilux Super HPS or USHIO. Both of which can be run on a DE ballast and boosted to 1150 if you looking to squeeze a little extra out of them :peace:

I thinknits also important to say that de gavitas DO NOT need the height I keep hearing people say they need.
I keep seeing people (generally new members parroting what they read) say that you need 10 ft plus ceilings to run them and they need to be 3-5 ft over the plants. That's total bullshit. I dont run them any differantly than a single ended hps with a hood that shape and I dont have any issues at all. My ceilings are 7 ft, light is about 20 inches over my canopy.

No light burn, no heat issues. I even bump them to 1150 watts.

I dont know where that myth came from but it needs to go away.

Maybe it's from the fact that when you run a lot of them you can run them 5 ft over the plants, but that's true with regular 1kw bulbs too so even still...

At 20" your flowers don't look like this?

Even Sunlight Supply warns against the massive infra-red radiation emitted by open DE Hoods. Honestly the above issue is one of my primary interests in LED. I feel with proper spectrum flower quality will improve and be more even from top of branch to bottom.

I run open hood 1000w DE and I have not seen anything to that extent. I am about 30 inches away tho with a lot of airflow and a high ceiling above the unit to take the heat.
