@Lights out, I run 730 for 5mins with all other lights (cxb 3.5k and v29, 4k.) Then 730nm for 10 more mins by itself.
13/11 light schedule during flowering

see, thats just the thing. It takes 2 hours WITHOUT sleep initiator, but with it, speeds the night process by 2 hours. So, really, if you think about it, without the "Forced Initiator" the plant only gets 10 hours of hormon gathering. 14 dark, 10 Light, 14 dark, 10 light is the way it should be for theroy purposes.
So now, the plant is 2 hours AHEAD, meaning 10 hours of sleep, 10 light, 10 sleep, 10 light, cutting 4 hours a day, or 120 hours a month, should knock off almost a week of flower time.??
I dont have flower initiator YET, but I know the value and benefits from it. SO I currently do 14 night, 10 Light, for flower. ( Im 3 days in ) They love it.

What 730nm LED set?
So what was the electric cost increase in those 7.5K of lights over 30 days in your area?
For me, adding 16K hrs a day was found to be not viable per the return benefit of that 2 hrs x 8 1K lights on the area I tested in..over a 30 day billing period...
Here, you pay at a higher rate as you raise K hrs to reach a new tier level. Not to mention the increases in pre and again at prime times use hrs....
Not saying it didn't work for me. Just not cost effective in my location vs. electrical billing rates vs. return benefit.
Nice 730 timing though. I did the same.
Bottom line, it works.
If I ran a closet or a tent or 2. I would be more inclined to do it.

Interesting to be sure.
In over 40 years. I have not seen that loss in yield when we changed to the 11/13 vs. a 12/12
too many strains to list over that period.
So it's an agree to disagree situation.....No disrespect given or taken.

Hey, (3500k-4000k) I was referring to to the Kelvin temp of the cob light.
I have a lil 2 x 4 setup that is 1/2 cxb diy and 1/2 old optic vero29. Ive strapped on a t5 UV and the 730 bar.
The 730 rig is a single bar, 8 diode jawn that I built back when the "far red thread" was popping.

likewise dr who, all respect to you my friend. ..i have tried a few different lighting patterns with different strains in the past and after having read the great feedback here i'm left scratching my head in wonder, i am a committed tinkerer which has it's drawbacks sometimes....
i think i had an issue with a knackered bulb that i wasn't aware of until recently , my yield went from 11/12 oz to 10oz then down to 7oz at which point i had eliminated all other causes and so replaced the whole lighting set up for a couple of 600w hids..... this may have been an issue when i tried the last time to run under a different schedule.

Cool, thanks for the comeback...
Yeah, you have the perfect set up for the use of the available increase in lighting from a 730nm set up!
I still run HID.....The whole thing was set up just as COB LED's were hitting the market, same for CMH and I needed a better footprint vs. the 3 available from CMH.....
Ordered one for vegging - reduce elec. cost........Better effective light delivery over my T5's and less power use if I go to a second one over the 1K MH for the last stage of veg.
Hows that T5 UV working for you?

I've been trying different cycles for several rounds, from 12.5/11.5, now down to 11.5/12.5. My driver was a better balance between finish times and yield. Second round at 11.5/12.5 and I'm liking it. No noticeable drop in yields but all my strains (control clones) are finishing faster than either 12.5/11.5, or 12/12. I do use 730nm initiators at the end of the cycle (10 minutes), also use 660nm initiators at the beginning. They did nothing imo under 12.5/11.5 (longest finish times) but seem to be doing the job both at 12/12 and now 11.5/12.5. Will be trying 11/13 next for a few rounds to see where that goes but liking the 11.5/12.5.

I had a ballast once, that would cook bulbs down by 60% in less then 2 weeks. Took a bit to notice as it was still running. Things took longer and developed slowly/poorly.....Light seemed dim when I really caught it (to busy looking at plants and for the wrong answer to the problem-lol). Got a new bulb (figuring) and in just under 2 weeks it was shot the same way. Replaced the ballast - problem ended.
Got me a good expensive light meter after that. Check my lights regularly....

I've been doing 10/14 for a long time with no initiators.

Please excuse my ignorance @CannaBruh but are the flowering initiators FR and EFR lamps ?

Your guess is as good as mine, I just shut the lights off. I think growmau5 was using mono LEDs?

i know he has a walkthru for F-red 5w diodes on tube
3-3W 730nm to be exact, running 700ma, 6watts at the wall

@Dr. Who re uvb
Ive been using the hortilux UVB t5 since last year when I broke my agromax. The hortilux works fine especially especially to smooth the transition to the much higher irradiance in the flower room. But I don't feel it has the UVB punch to effect the plants potency as noticeably as the Agromax.
I just ordered a replacement Agromax. I'll report back.

This plant was switched to 13.5/10.5 one week ago
Agromax bulb arrived Friday, I promptly toasted my lady by spacing out on the timer. Instead of 15 mins i gave them 4 hours. They have 5 weeks to go and I expect they will have a full recovery. No question in my mind that a fresh t5, agromax uv throws plenty of radiation. You cant see the effect so much in this pic.

Why are old threads frowned upon? You said that perfect. I couldn’t find the right words without being respectful.

Well handled bro.
as others have mentioned you are fine to DECREASE hours of light during flower, but you definitely dont want to INCREASE light by going from 12 on/off to 13 on /11 off as you will run risk of hermaphrodite expression at worst, at best you will slow your flowering cycle down and add weeks to the grow. Decreasing light mimics fall-wimter and signals the plant to bud and reproduce (if possible), but lengthening days are only seen in spring and early summer sending a signal to (re)veg or confusing the plant hormones (auxins).
yes reducing light during flower makes them bud and finish faster, typically.
