For example trying to tag @captainmorgan; old user last seen years ago: he does not appear in dropp down list: ... But hes still listed as a member at least to my understanding. Not asking you to fix anything just trying to understand, and maybe show a unnoticed issue :) Seems like theres...

Is this "90 days no login= dead account" the reason why some people doesn't come up in the dropp down list when trying to tag them re any other business? :)

And steal away this nice price from you guys? Coming up Im going to spend 3 months very far away from any growing; a tent and a light would just mean having to rent more storage space right now :) thx for thinking of me though :)

To me it seems hard to believe its a straight percentual influence; if the plant really senses the absolute percentages then what are all those actionspectrums with peaks and valleys for? I mean it seems like the plant definitely likes some parts of the spectrum better than others. This study...

Very nice post :) One thing i wondered about their research into blue light response is if they can reliably say whether its the blue light amount or the height of the blue spike that is responsible for effects. Do the effects come down to the % amount or the intensity of the dominant blue...

You guys seem to have this under control :) If youve made sure its the driver then some small notes: - those drivers usually have 7 years of warranty with the manufacturer, Meanwell. Id try to get it replaced under that warranty (Cypress are less than 7 years old afaik) thru the seller. Check...

Tube UV supplementation doesnt seem to work aswell as uv leds in tests ive seen. At least not significant results or even lower than led uva in GLA tests.

Another way would be getting a little water movement over the sink. A small fan in the middle will bring down temps on the boards but still generate the same heat in the tent. And yes OP it will provide all the light you need in a 4x2, figure out how to grow under 240 before pushing higher. It...

Their new range is 2.1 ppf/w which is a lot better than older models at ridiculous 1.3. I think there are better ways to get to that spectrum they use, more efficient, but i dont doubt the spectrum as something close to ideal for cannabis and aligns well with my own current working hypothesis...

Except for Moes voodoo veg tent where no laws of nature seems to apply. Thx for reminding me, lol.

While i havent been posting ive watched your grow thread: even the vertical grow with leds in the middle. I never jumped into the thread back then cause it seemed like the more posting the worse things got. I have feelings for anyone who has to live in fear of Russian/Soviet soldiers - my...

What kind of smells and terps are you getting in the new kitted tents? From what uv diodes and wattage? And in comparison to what you used to get:) Only asking to cross reference: added a fairly aggressive amount of "exotic blurple" to a few of our trays and got some very varied results: some...

Its more or less what youre saying? How does "plant dont recieve this in nature" become "this is dangerous to plants"? How does RF of the rectifiers hurt plants? Youve missed that step. Only showing that there is rf in a led lightbulb doesnt really show any danger from led growlights, that...

Yes, plants do love lights that emitt heat aswell as light. With leds comes an adaptation to this. Then seems to be fine. Also most incandescent or his have a continuous (all though very low in some places) coverage of the spectrum. Even hps has a small sliver of blue on one side. This is an...

@driver77 is using some mars uv/ir strips and could probably chipp in with opinions. In my opinion adding some uv and some "par uv" - violets lower than 440nm but still mainly within the par range is beneficial but you should be careful the lower you go in the uv range; you always need more of...

N No link? Ill try to get into this and google when theres nothing important going on cause all this sounds like loonie tunes a bit. Anything at all you could say about those EMFs from leds? Wavelength? Source within the diode? Anything but "lord save us from the led"? After google : Dude, the...

You are not understanding simple facts, growing with LEDs is like growing your plants under a microwave oven. -youd need to show that to thousands of growers, both cannabis and other crops, who use leds successfully. No spectrum change will change this fact. - microwaves are EM radiation...

Is there something other than "trust me bro" behind this? Whats the difference between one watt of HID red and Led red after they have been emitted from the light? What RF interference are you talking about? We harvest with radio on and we can hear when the phone rings in the speaker but nothing...
