@DapperDon do you really think these de hps lamps are full spectrum at 2100k ?would mixing those with a 6500k de not be better for plants say at a 2 to 1 ratio 2 hps to 1 mh? Because that was my plan for my next build
With that much lighting, you are entering into the neighborhood of diminishing returns. The co$t of running all of that lighting will not justify itself let alone the other co$ts involved with cooling an area with so much added lighting crammed in every nook and cranny. Simply put, you can achieve a lot more with proper planning, cooling, and spacing with DE fixtures than you ever will with bigazz hoods and led panels all over the place. I am not now nor will I ever be sold on LED lighting for growing. Can it be done? Yes. But there is not an led in existence that can compare to the quality that you will get with HID. To me, LED growing is the same as putting someone on life support. Yes it keeps the body alive. but there is no quality of life with it. I would suggest rather than spending added money on mismatching equipment chasing a dream, that you take a hard look at your overall system and then what it is that you want to achieve at the end and reverse engineer it to find what you may be lacking.
Almost a cliche statement. I talked more than a few people into getting Gavita and they all made similar comments after their first run. Others brands are just knock offs from Philips and Gavita inventions.But the very first run I did with Gavita changed the way I look at lighting. Nothing I have ever done up until then gave me the snow white granite hard buds
Not true, dutch kids don't start lashing out till they are at least 10 yr old. :mooning: FYI Gavita no longer sells to dutch cannabis growers/growshops...When the dutch get their feelings hurt they lash out like 6 yr olds, apparently that trickles down to their end users as well.
bro i was a bit of a sceptic on led but im turning over a new leaf haha pun pun,but no really check it out week 6 start.my same cut of mk i been running under hps for years,looks decent to me.starting to put on the frosty goodness as well.but yeah im not gunna pack more lights than i need in there,my plan is 5 foot centers on all de fixtures with maybe 4 mars panels in the corners but inside or in between the de lights.If it makes you happy then cool. I too am an advocate of "Different Strokes" as well. But with that, I am just not a fan of LED's or over lighting. I like a very streamlined and aesthetically pleasing garden and my equipment and layout are a reflection of that. PUN INTENDED LOL!
Really glad to hear, thank you for your input motherlode, do you run it on 825 during peak flowering weeks or at all?
Thank you both for your input,
By 90% you mean at 750w? Gavita isn't really clear as to what wattage the bulbs are designed for their optimal spectrum. They are called 6/750 yet they go up to 825 and also beyond with the setting label EXT, which from my understanding is another 5% boost. But I am assuming the best spectrum is at the wattage of the bulb which reads 750w, hence why raising it to 825 might fook with the spectrum and shift to more red and less blue, which would mean either more yield less quality, or same yield less quality. Dunno where I read it but Gavita does state these fixture at 825 is a BIT better of a spectrum than the 1000w fixture ran at 825, which I guess should be obvious. Regardless I will be emailing Gavita just to double check if the spectrum suffers and how much when running at 825. Also, do you mean you veg a bit longer motherlode? that is why you don't run at 825?
Thanks guys for the input, sorry to the fella that started the thread and I am getting off topic here, but instead of PMing I'd rather have the community see this info as well.
Yeah what i see is if you dim it down to 600 or lower its gives off a really red spectrum and 700 and higher is really white or blue light.at 800 its hard to see any red but im sure its still in there lol.after you stare into the lamp @800w for 20 or 30 minutes its hard to see any colors at all or anything else for that matter lmfao :)
According to Gavita Rep:
The highest bulb efficiency is at the 825W setting.
The highest blue/UV is produced on the 600W setting.
The change in spectrum is minimal and so you will have 0,5% more blue/UV on the 600W setting than on 750W.
The difference between 750W and 825W on the blue/UV is 0,3%.
If you want to add some more blue to your crop in flowering phase why don't you use an additional light source for that?
We recommend to use plasma fixtures for additional high quality light which includes UV-A and UV-B.
