Informative Far Red video
Really flash light meter (wickedly expensive)
I want to thank @maxlev for turning me on to this particular highly prized addition to my lighting toolkit. Been looking for something like this for awhile, most similar high quality tools are much more expensive and more lab-like.

Made me feel like this when it arrived this morning.


More to come when i have some time to play with it...

You're the one trolling mate. Even if you pretend you still don't realize this after about a few dozen people told you so. It's of course all those people that are wrong while you are the brilliant one out.

Still, I can't imagine the great wisdom you will dig up from where the sun don't shine using this device. Comedy gold for weeks to come I'm sure.

All reds up and ready to grow some ginormous colas.

Far Red Bar: currently running for first 15 mins after lightsout

View attachment 4189247

HLG QB-35 Emerson Boards: Four of them mounted in offset pairs on each Timber 48sams, will be running for full lightson once stretch is done.

Far red bar is also on (never will be on when other lights are on), but relative intensity perceived by human eyes is too low to see when other lights are on.
Spectrum of two 3000K 48sams (eight 288 V2s) and four qb35s in 4x4, at cola tip height, approx 24” from lights:

Massively Yellow, Orange, Red (570-585,585-620,620-780)!

Here’s hlg 550 V2 spectrum:

Yea, that's with 4000 Umol. Some strains like a little bit less, so if you still continue to see unwanted stretching, I would lower the time a bit more. but this should be a good starting point for you.
Hey mate!
I just ordered a far red initiator from Rapid led (https://www.rapidled.com/far-red-initiator-puck/)
They 4 x use Cree XLamp XP-E Leds. Would you recommend I run these for 1-2 minutes before lights out and 1-2 minutes after lights out? My grow space is 2.5x2.5x6

Thanks < 3

After reading designers info in old thread on here.
On for 5 min after lights out.
On before lights on does nothing.

Dont know if I agree with that, because u can achieve the same affect with 90cri and there is no far red at lights out with it.

Which is exactly what I wouldn't want!
SO I think I'm going to play it safe and just do 2 minutes of FAR red just after lights out.
Lots of people do 15 mins, post your results with 2.

What lightson hrs:lightsoff hrs you going with?

Not sure if you saw it, but if you diy, rapidled’s emerson strip does both emerson and initiator effects, pretty sweet bogo..,

Hlg has an emerson bd but not dual purpose....they’re workin on it, i’m told...

might want to get a Sonoff timer for it. few bucks well worth it for this puck. You simply splice an extension cord, and just plug it in.

I actually did see that one! but since my room is 2.5x2.5 and the coverage for the little guy is 3x3 I figured It might just be enough to create the emerson effect on its own no?
I'm going to be switching to flower in 3-4 days. Will do 12-12 I figure and just two minutes of far red after lights off and see how that goes.
The funny thing is that Growmau, the maker says in his video to use it for 15 minutes too. so I'm wondering mhm.

I actually was going to use it with my Wemo Insight. You can schedule on and offs times as well as monitor the energy draw through mobile phone. Should be ok right?

I believe the one i linked might be too long for your setup. That puck i thought was only a far red initiator, does it have red and deep red diodes too, you need them for emerson?

I’d go with 15 mins, won’t do anything negative if other lights are out. The story (anecdotal as best i can tell) is that you can go upto 2 hours longer lights off (10:14) to get some additional flowers, and that the get closer to 12:12, the extra sleepytime helps shorten the duration of flowering period.

I’m running both full lightson emerson and 15 min lightsoff far red (12:12), my feeling is that the emerson is doing way more than the lightsout far red, but i have no evidence to present.

I trust @Randomblame ’s opinion, maybe he’ll chime in.

One suggestion, don’t start emerson or initiator until after stretch, unless you’re trying to boost internode length.
