Anyone running 315 CMH and 600 HPS in a 48X48?

Did my last grow with 315w cmh and 600w hps worked awesome. Vegged with cmh and flowered with both. Grew fat buds that got me high as fuck, I recommend it.
Soon I will go full Led 50% because I want to 50% because power is so expensive and I want to grow more weed (who doesn’t lol). I ordered a grow tent 8x4 to flower in. I’ll be running 2 400w version of this light. Seems to be working for my mate he has yielded ok but he said he would get 20% bigger buds with his old 1000w hid setup v his 600w version of this light.EEB53167-291D-4077-9625-937D32B0DECA.jpeg
 
Your assuming I havent seen the many articles about "why 600 watt hps is more efficient than 1000 watt hps." I said I've read them. I've seen them. I've seen it spouted over and over. Fact is I've seen them and i dont care to read them again just because you posted the link.

Guess what else can be linked? Why burples are actually good. Theres science backing that as well but in practice we have learned differant is true.

I dont care what people think about my attitude or how i come across, I've tested the 600 watt extensively. I've tested 1kw extensivly. Ive also ran 400 watt. I've tested many many differant makers of bulb and differant spectrum. I know what works and I've been doing this a long time. I've seen countless new growers who say they know everything about why this or that is better than a 1kw hps but then for one reason or another a year or 2 goes by and all the sudden they are using the 1kw hps.

You may notice I never disagreed about cmh though. I think cmh is great and I recommend it.

I just dont think a 600 watt hps in a 4x4 area is going to hold a candle to a 1kw hps running a hortilux super hps.

Hate me all ya want I really dont care, at the end it's his grow an he can do whatever he wants, if he wants the best looking most resin covered bud then he will go with the 1kws. If he think the 600s are better then hes going to get smaller buds that just dont compare.
If I may explain I'd like to at least relate to you on an eye to eye level, if you care to understand the main reason why I have experience with the 400w mh/hps setup, then all one needs to do is look into the past, which setup would be the least likely to get noticed a dual 400w setup or a dual 1000w setup, the setup me and my friend had going consisted of about 1200w total, fans, and extra fluorescent bulbs included, smaller bulbs + smaller space: less chance of anyone noticing, it's what we felt safest doing at the time and we felt it was the smart way to do things, and although it wasn't even my grow at the time, I was there every other day for months at a time checking on things, enough to have caught on and say I've had experience with them and to have seen what they could produce, if things weren't so life threatening to have gotten caught at the time maybe we would have went with a larger setup but me personally I was in my early 20's I wasn't trying to catch a 20 year sentence over growing a meager amount of medicine that I/we needed at the time.

So if anyone would like to know, I come from mostly outdoor and greenhouse growing, I'm still new to indoor in some ways but I'm working my way toward being an intermediate, I don't feel a newbie is the proper word for someone who's been growing and been consistently working with and around plants for 20 or more years, the great outdoors the best place to start gaining a level of growing skill for free other than your own time spent putting the work in, if you check your plants daily what does it matter if they're indoor or out? It's about the time you put in with what you have, I spent years growing legal plants with a goal of someday having the chance to use my skill on Cannabis and other desirable medical plants so that I could have the cleanest purest form of the medicine I seek that is realistically possible, and now's my chance so I'm starting over, and I have chosen to start back up with LED this time around, I may revert back to some HID, but like I said I have experience with smaller bulbs and it's going to be my choice to stick with the lower wattage because that's what I'm comfortable using and that's what I've seen enough of to know I can still make good things happen without needing a larger fixture and bulb setup.

My blurple setup are just x2 250 watt vanderlife lights that I bought off Amazon during blackfriday of last year, I actually have access to a third if I need it over at my father's place, the lights were half price at the time so we grabbed a few to test out, they run a bit warm but they do put out some intense light. The blurples I have are not going to be ran by themselves I'm going to add extra lights In with them (even if it's just fluorescent) i've got 6 6500k strip lights that are 30watt each that I had planned on running these with the blurps but it looks like I need to figure out how to dim them down first, as initially my plant reacted to the light I bout with curling leaves like scolded by the light, but I must have had them too close and no dimmer, so I'm learning to solve the issue as we speak.

I'm not a professional, I'm just here trying to help out with what I am able and I think I do pretty well, I try and stick to topics I know about mostly, and your correct @growingforfun I still have much to discover & learn and then later pass on my knowledge, but that doesn't mean I can't have a say on a topic that I've atleast have some experience with, I know my level of intelligence and I speak when I feel I'm able to answer a question, plain and simple. Thank you for your input and for showing me your viewpoint, and yes their must be something special about the 1000hps otherwise I wouldn't hear about someone using them day in and day out of this forum, I am a fan of hps I just dislike the spectrum, but here I haven't seen the latest and brightest bulbs either I haven't been around hps in close to 8years, so please bare with me I don't know what might have been updated since I was using the smaller 400w setup back when.

So if I say something that might make me sound like a newbie, that's just because I'm not in fear of what others might say, I know my level of experience I can portray what ever image I choose and then the next day go purchase the next greatest light and be caught up with everyone else in no time, all it takes is a little intelligence and know how, it's not about who's got the best light it's all in how you use it and proper spectrum, from what I've seen so far one light does fill in a full spectrum array of light on its own, every light source has its flaws and inherent disproportions that make it sub par to sunlight, this is why many people have found (like myself) that the best option for broadening the light spectrum and coverage is by not relying on one source or type of light for a plants photosynthesis needs, if photosynthesis is what is most important to the plant then spectrum should be held at a much higher value than most of us here are adjusted to, spectrum is number 1 in regards to light sources, just look at all the past success people have had with simple fluorescent bulbs, why because of spectrum, there used to be dozens of different manufacturers and CFL bulbs that had all types of different spectrum(cheap too), and that's why they did grow some decent plants at the time, main drawback to them is broken glass and mercury poisoning that's why society has moved away from them, other than that they weren't the worst light sources, definitely not HID but they had there space in many a small grow.

If spectrum isn't important then why are so many LED manufacturers loading their light fixtures with multiple types of diodes, pretty soon we are gonna have a rainbow assortment of diodes of the very best lights because those lights have been manufactured entirely based on spectrum alone, while we also see the broadened light bar strip kits with spacing in between each strip all mounted to one fixture, you know the big square LED setups that are selling for $1000+ , these companies know what they are doing, just look at all the attention they are giving to spectrum and wide canopy coverage to see what they have discovered to work best in their new designs.

I'm not saying anyone is wrong here, I think we are all capable of coming up with a good argument and just feel we need to respect the fact that another person isn't completely wrong, most arguments there is correctness on both sides, it's just that thin details that cause the disagreement, it's all about respectfully revealing your viewpoint of the matter and allowing yourself to be open to how another person views a topic or has had experience with said subject/topic or idea.

I'm not offended or upset at all, I just wanted to clear the air and hope to remind you of where some of these lights had first gained their popularity and why people where fond of certain fixtures or types of bulbs and sizes over others, their is more to it than first meets the eye, there is some history involved, that's my reason for posting this detailed message, if anyone here would like to add some history and their own experience please do, I would be open to accepting any and all viewpoints anyone here could offer.

Thanks for reading, take care.

So much to respond to in there... I'll take a few bites though.

Led companies are selling lights for 1k+ because people are uneducated and have more dollars than sence in many cases.

The hortilux super hps has a amazing spectrum you should look into, I didnt say spectrum doesnt matter, I said trying to mix spectrum to get some ideal doesnt matter because as far as hid goes the hortilux super hps IS the best flower spectrum.

315 watt cmh is very nice, I'm happy with the results im getting from it, I was a little more happy with cmh until a couple days ago though because my hps buds of the same strain beat it considerably on quality this time around. It's been a trade off for the winner my last 3 runs so it's still inconclusive.

When your trying to be safe the answer is perfect air filtering not more small lights.

A single large fan running at reduced speed makes less noise and move more air than small fans.

Take the wire screens off wall mounted fans and put them on low, makes less noise and moves a lot more air.


Hope some of this helps.
 
If you want to get into led, great go for it. Theres a lot of great options out there. Just know to get a led that better at growing than a HPS your likely going to have to assemble it yourself, and theres a lot of great information on that here. Unfortunatly burple LEDs are actually less efficient at growing bud than HPS is, as you read up around here you'll find that's a fact. Burples cause a lot of problems for plants and when they work they only work alright.

Well that would be an issue, but only if your growing a strain that has a high terpene and scent dispersal from out of its flowers (& room size), the plants we were running put off very little scent, so actually no charcoal filtration was needed In the small setup we were running, in a rural residential area, scent wasn't much of an issue, until harvest time of course be even then we were able to get the scent down within a few days, we probably were a tad more risky than we needed to be as far as air filtering, you are correct.

If you're speaking of air filtering, one thing I dislike about the vented fixture is that what happens in the event of a fan failure while the bulb is still running all day, do most fixtures come with a shut off fuse? I just don't like the excess heat factor that has to do with a vented HPS in the event of a fan failure, I suppose running a dual fan setup would help piggyback the system in case of one going into failure, that's just a little side idea I thought of, not to side track this conversation.

Thanks for your help.

2 things, it ALWAYS, ALWAYS, ALWAYS smells more than you think.
Fans are less likely by far to malfunction than your light.

In 10 years I've never had a fan fail. I've had several lights fail. I've had lights start spewing sparks from the ballast, hoods fall, numerous things.
But a fan has never failed me. I've had parts on fans start to wear, and the ball bearings start to go out and make more noise but continue working perfectly fine until I replaced them. I actually still use the first 2 inline fans i ever bought.

Ok awesome that's good to hear, yeah being mostly from outdoor experience there was little ever a need to use a fan at all, now in the greenhouse yes, but it wasn't for the purpose of dropping the temperature that a light bulb puts off, it was more just for motion of the leaves and overall cooling of plants in general, (or to evenly spread heat from the heater/heaters during winter) never really used a small ducting type of fan in the GH either, only larger mass air moving types like a box fan or oscillating pedestal fans, that and the thermostatically controlled cooling fan up top & center but it probably used close to 2000 watt just by itself kicking on, plus the opposite front or rear vent that opens to let the fresh air inside.

So yeah no I'm still discovering all there is to know about indoor and the various differences, there's just a few things here and there, like for instance I did not realize how durable a small vent fan could be, but now that you've spoken up about it I feel a bit different about the matter and not as concerned as where I once was towards the over all reliability of those vented bulb types of setups, your reply made sense to me so yeah I do think you're correct the vent fan would probably be the last item in your setup to fail, and may give signals such as vibrations or sound before they do break entirely, I agree with that because I've seen a few break down this same way that you've mentioned, I had a few fans that would work on high, but then would not work on med or low setting, then the fan slowly just stops working on high shortly afterwards, so I agree fans aren't the hardest items to diagnose as to whether they are functioning properly and shouldn't be that much of a concern, thanks for helping me clear that up, seems logical.

As far as scent goes, you are most likely right, just like the light bulb spectrum we've been speaking of, one nose can't smell every scent, I shouldn't assume my own nose would pick up every scent that another person might pick up on, so that's another aspect that indoor growing brings to the table, definitely something I could use a bit more experience with, thanks for reiterating this for me, I would like to stay below the radar as much as possible as far as any neighbors catching on to what I'm legally doing at my own home, although legal it's not for the world to know, not in close quarters, if scent places me at risk then I do need to appropriately expend some effort there.

Thanks.

Yes it seems like it is just difficult to match a 1kw HPS fixture for fixture of any kind of lighting...now in regards to multiple fixtures, such as many 315w CMH's vs a single 1kw HPS or many of those 600w LED's you posted pics of vs a single 1kw HPS is a different story. I think that is where you can make up for the 'less bang for your buck' light fixture per light fixture. My point is, with all of the heat 1kw HPS creates, many environments are only capable of using 1 without overheating. Whereas, with the LED's you shared pics of or a CMH, could have multiple fixtures creating more uniform coverage over larger spaces, sort of compensating for the loss of light intensity from a single source. The downside, of course, is the upfront cost. That's why, only if possible, I prefer using both my 1kw light and cmh (even though that could also be swapped with LED's if desired) to be a pretty good setup, if you can deal with the heat which is a matter all in itself.
 
No problem, happy I could explain it well enough.

I've learned any smell can bring in the wrong sort of person. Mainly meaning junkies looking to ruin your day an make a dollar. Had so many friends end up wishin they didnt go threw things.

When people come to my house there is no smell ever. I run 3x carbon filters at all times. One filter exhausting from the room, one filter scrubbing the room, one filter outside the room. Each filter on it's own is rated for the space.

For me this is the area that is most important to focus on being perfect, and an area I STILL want to invest more into believe it or not.

True.
The heat is also a factor I live in Australia hot summers with hid and air con it’s too much power. Electricity bill’s here are ridiculous. I’m hoping this summer to just run leds and air con the six hottest hours of the day. In a perfect world I’d run every type of light just because I love growing and comparing. Like the Ts 2000w Mars Hydro is giving my 315w cmh a run for its money, which never In a million years would I of thought that would of been the case. I’m doing a side by side scored the led cheap off a mate who’s wife wouldn’t let him grow hahahahaha, lucky my wife loves it as much as I do. But I also will chuck the hid in for the last month of flower just to get the buds dense

I run a filter in the tents and outside the tent I agree prevention is worth every dollar

Oh my, I feel sorry for you buddy being in Aus growing, the heat there is seriously no joke!! At least it's winter time over there for now though, right? Or is it still hot then as well? Lol anyways yeah I can totally understand you're hesitance to run HID's, it's a fine line to walk between achieving the light intensity for dense buds, without getting temps so warm that it makes the buds airy. I tried experimenting with running 1, single autoflowering plant under just 1 315w CMH light in a 3x3ft tent and was able to pull close to a half pound untopped and untrained. So, I've just been trying to recreate that yield except on a larger scale in my 6.5x6.5ft flowering tent with 4 plants, and that's what I'm hoping that my 2x 315's and 1x 1kw HPS will achieve, so fingers crossed!
