Thx Ice for testing this out
Is there any knowledge of W vs area or how much these 70W IR covers ?

Looking pretty fine Ice
Nice, looking forward to the grow

Hey there Ice, what is that clone tray with the brown cubes? I see the water level is sufficient to be above the bottom of the secondary trays. You should grab an air pump and little stones that can fit between the secondary trays. This will Oxygenate the water and make rooting much faster.
Edit: Oh yeah, plant's look great!
Hey Billyjack! glad to have you! I'm looking forward to it too! can't wait to see if these Far Red panels do their thing with a extended daylight flowering
Thx Ice.
I see these panels are brand new and not available yet ?
All I see is EM 1 and 2 with 660 + 730nm.
I think about use them mainly as flower trigger but staying at 12/12 as I grow perpetual.
So still undecided if that make sense.
Please let me know what Paul says. I have one of those too. Got it the same time you did. I haven't used it yet because my understanding of the emerson effect is limited. I just think I'll stay on 12x12 and run it for for hours during the light cycle like you. It will be interesting to see the differences in your yield.
Thanks man. I really enjoy your posts and grows. You are one of the few folks I follow. The site has many great growers but I do not have time to follow them all. One of the things that I learned was to grow within my skill set, which is simple grows getting a decent product. You on the other hand are a master alchemist doing great stuff. You have a deep knowledge and you are always willing to share what you know.
He got back to me, but I didn't understand the response so I asked for a little detail or clarification. I'm going to try it with the 14/10 schedule and see what happens, If I see something odd or the plants struggling to flower than I may bump it down slightly but I have a feeling from everything so far I have read it should work.
Right now I'm using it for 4 hours during the middle of my 18/6 daylight period, so it comes on around 6 hours after the lights come on, runs for 4 hours and then goes off. I'm not really noticing much difference other than my plants seem to have much larger leaves on them, similar to the old HPS and HID grows I used to do, where LED seemed to make for slightly smaller leaves, but it could just be my eyes too, as I don't have a side by side to compare to. Whether or not the Far Red is really contributing its hard to say, but I guess it can't hurt since the sun has a 1.2:1 ratio of Red/Far Red, and most LED grow lights are much higher of a ratio.
I'm wondering how adding the Far Red may effect trichome or terpene production, but I haven't really found any info yet on either, but will definitely post it if I find it
Actually, lol...
I can imagine a scenario in which, for whatever reason, the "darkness" of the dark period is sub-optimum. Say... more light getting in to the grow than the average illumination provided by the sunlight reflecting off the moon at night. Maybe enough to interfere somewhat with flowering. Is there any way that these kinds of wavelengths could offset this?
I don't mean a short period of (relatively) bright light - I mean dim (but still significant) light during the entire lights-off period. So it would not be a case of quickly firing up the "far red LED panel" for a short period of time and then hoping that the remainder of the "night" would then be sufficient. But maybe, IDK, leave such a product on all "night" long? Or does it not work like that.
I'm feeling dumber by the minute!

I also thought it should be used just before lights out, 10 to 15 minutes of far red at dusk.
Just watched Harley Smith's class "How to Maximize Yields" and he actually mentioned along
with the fact Far Red ( 720 ) puts the plants to sleep and that the Blue Spectrum is responsible
for waking the plants up

Abstract
An experiment was conducted to determine whether the high R:FR ratio in high pressure sodium (HPS) lamps contributes to lateral bud breaking in roses. Rosa hybrida cv. `Samantha' plants were grown under HPS lamps, HPS lamps fitted with blue gel filters to reduce the R:FR ratio or metal halide lamps. Spectral graphs showed R:FR ratios of 1.05, 0.5 and 3.8 for HPS, filtered HPS and metal halide respectively. Although the R:FR ratio in metal halide was notably higher than in HPS the total energy in this range was much lower. At a 24hr supplemental PPF level of 70-75uEm-2s-1 more flowering shoots were produced under HPS and metal halide lighting than under filtered HPS. There were more dormant shoots under the filtered HPS. No differences in quality were found among flowers from any treatment.
