Wow, never mind that, my last order was from Seedsherenow, I really would recommend them. I just checked Darkhorse again, they're sold out of almost everything and aren't carrying half the old vendors.

Dude, wait, what?! Your alien blues looks totally different than mine. Here it is about 2 weeks before chop.

jusess christ, yours look 5 x bigger than mine. there is a lot of different heritage in that strain, could be many vastly different phenos.

That's what I was sayin. Huuuuge calyxs

@Growmau5 seeds here now also does not say how many seeds per pack. 5? Cause the dank team sells 10-pack La Plata strains for $60-75.

Yeah man, if I'm not mistaken (could very well be), the Alien in the Alien Blues is Alien Tech x Tahoe OG. Alien Tech was a land-race Afghani brought over to the states by a soldier who I believe is Obsol33t of Franchise Genetics. I think I just had the luck of an atavistic Afghan pheno, I was pleasantly surprised! It seems like everything grows like an OG nowadays.

Then again, DNA has that Martian Mean Green, that has nothing to do with a land-race, and I've heard crosses with that being referred to as "Alien xyz". Biology always pissed me off with it's lack of persistent nomenclature, cannabis isn't even the worst culprit. Do some work with master regulatory genes, hox genes, desert hedgehogs, sonic hedgehogs, robotnikin re-uptake inhibitors, all pure fucking nonsense made up on the spot by the guys that discovered them. This is why I chemistry.

yes they do. its just hidden in a drop down box. you can select 5 or 10 packs based on stock level. if 5 packs are out of stock, i believe it doesnt even show as an option.

another knock against dank team is. you go to the website and it shows every strain they have ever carried, you have to click thru 2 or 3 page reloads just to find out , the strain you are interested in, is out of stock.. with that said, they do have a very diverse selection of seed companies, general with full lines.

first I have to say thank you !!! that goes out to all the members who have freely put their hard earned knowledge and experience
out here. thank you !!!!!! I have 2 cabinets that measure 41" w 28" d 42" tall . I currently have 2 85 watt hans panels plus 1 htg
supply supposedly 250 watt panel in one of them. killawatt tells me 252 watt total. I want to purchase 8 3590s for the other one .
my questions are what is the difference between 2 and 3 step binning witch is better? is there a difference in driver efficiency
when using a pot v pwm dimming? how long can the leads from the driver to the cobs be max? I want to put the driver outside the cab. less heat to deal with. again I can't say thank you enough!!!

I don't see this asked a lot, nor do I see many people running their drivers outside their room. I do just that, however. I called the guys at Meanwell, your driver leads should not exceed 50 feet, so you've got plenty of length to work with. The driver is 100-102% running at capacity with no resistor or pwm on the control lead, and drops to 98-100% when you have a pwm controller or 100k pot, doesn't matter which. Just closing the leg reduces the driver output to 100%, you won't really notice a difference though. Top bin just means that from the factory, there might be a 2% difference across a product line in terms of output when tested, so the chips that test higher than others go into the top bin, the rest go into subsequent bins. It doesn't really make a huge difference, as we're talking about the difference in quality control for chips that are made with a pick-and-place robot in a sterile surface-mount production facility.

The 2,3 or 4 step Macadam ellipse represents the quality of the color as it relates to human perception. It's apparently not something that affects plants and should be disregarded.

Much better explanation of binning, thank you Danielson

So is binning just a CRI thing then? I remember looking at some graphs back in the day, and it almost looked like lower CRI chips of the same temperature had more of a shift into what I would think is photosynthetically active ranges. Like I think higher CRI makes red shift toward yellow, where I think it might be beneficial to have the red in the case of photosynthesis. This would of course be a deficit if you are trying to illuminate an art studio where color rendering accuracy would be where you would be shopping for a high CRI chip.

I might want to look into high temperature, low CRI chips. That'd be cool, like a 4500k that was really unbalanced so the light was blue-ish pink. I think that's what is going on with this really weird 36v Citizen CLU044 Vivid Series Light-pink chip that I have running right now, it isn't just pink, it's got like an eerie blue to it as well. I think if Cree made something like that, it would terrorize a garden.

Wait, holy shit, YO GG! I need you to twist whose ever arm you twist to get Cree to pick that up. Damn that's fucking rad that you can do that!

thanks allot!! now I can move on to the next step. here is an idea for gwowmau5 or anybody else for that matter. I saw I one of the teck talk videos you were trying to think of a light mover. a driven vertical shaft with a foot (for want of a better word) sticking out horizontaly . the light fixture would hang 4 to 5 inches off center. that would be an 8 or 10 inch orbit around the center of the driveshaft. my thinking isn't about more coverage but moving the shadows caused by the upper canopy. my guess would be 4 to 12 rotations per hour. users choice .give it some thought

Ya just need something to bump the light every few seconds , I thought of this as well

I like the smaller seed companies that carry their own product ,but it's all ways limited production
snooooze ya lose like the Crockett gear GG talked about : Now sold out !

Hello Growmau5,

You run your cobs at 0,7a and each driver provides electric power for 8 cxb3590s.

Is it possible, lets say for a limited time for each daily 12h-light-cycle, to tune up the cobs up to 1,4a with the same driver set up? As I understand the whole thing, voltage is fixed, while amperes and therefore wattage is flexible.

The idea is to simulate intensive daylight comparable to noon hours when the sun shines most brightly for a limited period of time...

Thanks a lot for answering!

PS: I am aware that I sacrifice lumen per watt efficiency, but I think for a boost of overall lumens its worth the extra electric power for 2 or 3 hours a day...

no mention of the appearance on the dude grows show? spreading the word, great stuff @Growmau5

WHAT MAU5 CONGRATULATIONS DUDE!!!!!

The thing about white COBs, there's no UV at all. My belief is that the addition of UV-A is beneficial for potency while having very little detrimental effect on yield, as UV-B does. The Black Dog site has a page about it. They found UV-A was enough to enhance potency. The good news is that blacklight CFLs are cheap, unlike reptile lights, and you don't need much, maybe 10% of main lighting wattage.

Dude, that's pretty cool, I didn't know green was the brightest color to humans. Totally makes sense from an evolutionary standpoint. Like green is everywhere, all that vegetative matter that is reflecting green light, it would be beneficial to see in enhanced green. Like if you lived in the ocean and hunted by sight, you would probably see blue as the brightest because there's so much blue reflection. Very cool.
