H562D and F562B ... those are both single row and 22" so what are the differences between them?I want to know which one is better and why cause just looking at them they don't seem to differ that much

What is the difference between gen3 single row 2' H and F series?

It's a little plastic screw lol

Basically it's a difference between night and day temps...the bigger the difference the more your plants will stretch...if you want to slow down stretch keep the temp as close as possible between night and day or lower them as much as you can for the first 3 hours when your lights turn on

I use temporarily 5000k 90cri for veg and 3000k 90cri for flower...more than satisfied with both

Just finished auto anesthesia from pyramid...bought 5 more right away and put them to germ so that says it all...if foto version is anything like the auto, here is what you can expect...frost and glue, this is by far the frostiest and stickiest plant i have ever seen or grown, nothing comes even...

Good to know, it seems like they stabilized it a bit...it had a reputation as a bit unstable but so good that despite that everyone wanted it lol...lucky you didn't get the wild pheno, one guy ran out of height in a 7' tent, said he tried everything but couldn't even slow it let alone stop it

Dim the light, volume on max, full screen, press play :bigjoint:

Looks like you got the one with a lot of flowers...looks beatifull mate :clap: Did you defoliate and did you see any bananas around maybe?Some reported it tends to go hermie if you slam the door shut too loud during flower

Maybe the ratio of far red and deep red is different?I dunno i am guessing here, i know one makes them stretchy and the other is more focused on developing the roots so plants stay shorter...should check where the red peaks for citi 6500 and cree and veros 4000 and compare if there is any...

Do you think for different spectrums it could change a bit more?Altough i don't see it making that big of a change anyways, even if it would be a 5% change it should still be pretty much the same and shouldn't cause visibly bushier plants

I think i read something a while ago also about the spectrum shifting from 32 to 36v...it was something about 3500k shifting it's spectrum to green the higher the voltage of the chip...basically the result was that the chip lost around 20% red photons when switched from 32v to 36v which doesn't...

I think if both drivers have the same efficiency then the efficiency of chips/spectrum/ppf should be exactly the same

Lol there is always comfort in company but i think we actually might be correct in this case...or at least we are somewhere on the right track...we need someone with the proper tools and a will to experiment

Lol me neither but i see a lot of apogees and spheres on this forum so only matter of time i gues till someone does it...in cree datasheet the spectral chart is at 2100mA...i would be curious to see the same chart at 700mA, will probably not be a huge difference but i suspect it could shift a...

On my phone so was replying to you and vertnung at the same time, he asked about height...i think you raised a good question and am also curious to know the answer...there is also a factor of temperature of chip...from my limited knowledge the higher the phosporous coating gets the more spectrum...

@Evil-Mobo You can lower the lights only up to a certain point...i noticed it on my 5000k 90cri...i use a lux meter to calculate ppfd and it shows the spectrum color quite correct...at 30-35cm(12-14") 3000k is +-1% 3000k and 5000k is 5000k +-1%...when i raise the lights to 60 cm the meter...

Didn't notice any spectrum change when dimming...i only noticed it with raising the lights, the more you raise the more spectrum shifts to red

Here is what the guy from dinafem said to me when i inquired about it some time ago Our critical+2.0 is also called the bilbao cut of critical as she is sold in a lot of Spanish cannabis social clubs. She has several phenos which have a typical 2-2.5x stretch in the bloom stage. She produces...

11 pages of pure crap with no relevant information whatsoever, i think this is a record even for this section of the forum @the topic - Yes mate they are worth it
