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.
