Hello! Would love to learn to grow as well as you do! Just got a brand new es180 v3 light and am I hoping to learn some new techniques to become a better grower! You are amazing at what you do! How soon do you start bending your young plants? Do you top them? Or just start bending? I’ve been looking everywhere for some advice and how to supercrop the main stem…
I guess what my goal really is, is to try and make the main stem as thick as possible, and obviously you are very good at that.

Another amazing grow!

My decision to finish the first seeded clones in a tent on the same 13.5-10.5 light schedule as the larger room but without EOD far red has given me some usable information. The cloned girls receiving far red for 15 minutes after lights go out have continued to stay in flower but have still been stretching well intro week 5 of flower but they appear to be starting to slow down and adding some weight. The clones without the far red, which were much deeper into flower when moved from 12/12 to the 13.5/10.5 and have started to reveg a little. The stretch and reveg seems to be occurring mainly with my Sativa dominant hybrids so I will be adding a small IR led to the seed tent to make it convert back to flower. In 2 weeks or so I will increase the darkness and continue lengthening it over them for the remaining 5-7 weeks of flower. I hope to quantify some of the expected increase in flower time with the longer light cycle as compared to previous runs of the same clones.

@dbrn32, You made the comment that smaller seeds were more desirable provided they were fully mature. What is the logic behind a smaller seed versus larger seed?

Killin it my friend… 
How many watts of light do you have going in there…?

Your tent never ceases to impress me

That tent has approximately 3400 watts over the 65 sqft of canopy, ranging from UVB through IR. I will be changing up the layout as I shift to a smaller SOG for pheno-hunting and breeding.

Another interesting result that I am noticing with addition of the EOD 730nm IR is that the leaves start praying towards the lights within the first day of adding it. Even the burnt larger fan leaves that are essentially dead or dying with almost no green left start lifting toward the lights after a day with the 15 minutes of IR.

Thanks for the info @Stonedrus amazing work.
Also Intrested to see what @dbrn32 says about the seed thing.
I do want to ask if you can clarify are you running red and far red for the emerson effect or just far red?
Secondary can you explain what exactly your doing here lol?
You took clones, at what point?, you were deep into flower when you took clones?
And now your running some with far red from one cutting batch and another without far red yet your running them both on more daylight hours then flower hours?
Finally you are adding a small ir led to the seed tent to switch them back into flower? Your seed tent is in veg?
All very Intresting but confusing sorry I haven’t followed as closely as I should have I Geuss.

They are said to higher germination rate and pop faster.

I prefer working with clones after you have selected your mothers and fathers so that results can be duplicated. Seeds can have a lot of variation and do not provide a true comparison. I only take clones in veg so that there is minimal recovery and turn around time.
The mothers, and vegging clones currently run on a 24hr light cycle with a heavy dose of blue led to keep them compact. For this round of flower, the 10x10 and 4X8 were both running 13.5 light / 10.5 dark at flip to flower. The 10X10 flowering tent was running with both 660nm red and 730nm IR running for the Emerson effect throughout the day hours and then 15 minutes of 730nm after lights go out at end of day to speed phytochrome conversion and induce flowering.
I moved the first round of pollenated females, who are producing seeds after about 5 weeks of flower from their original 2X4 tent at 12/12 over to the 4x8 which was on 13.5/10.5 but did not add an IR end of day light. The girls with seeds were left to continue flowering at the new light schedule while the next round of clones went into the 2x4 to pollenate with the next male. I will move those girls over to the 4X8 to finish up and the next round will go through. Wash, rinse, repeat.
The clones in the 10X10 have continued to flower with the EOD IR and 13.5/10.5 schedule but the clones in the 4X8 without IR started to reveg a little over the last few weeks. I have added an IR puck to the 4X8 running on the same timer as the 10X10 to fix this issue with phytochrome conversion, which should kick them back into full flower, while the seeds will continue forming. I have begun adding more darkness to encourage them to pack on weight and begin to ripen the trichomes.
Clear as mud.

@nicky,
I have been manipulating the spectrum of light to influence different end results that you may see in phenotypic variations of the same strains. The Led lights allow for some very unique tuning of the spectrum for the plants which modify growth characteristics, but It is the same principles as using a CMH, HPS, MV, and fluorescent reptile lights.
330nm, 365nm and 385nm increasing THC and resin production
450nm for node spacing, leaf production, and terpene enrichment
660nm for flower development and white tips on buds
660nm + 730nm for Emmerson effect (debatable on the impact)
730nm End of day phytochrome conversion
White light at varying Kelvin to ensure a balanced coverage over the canopy
In the old days we would use green lights to work in the gardens at night, but I am not sure of the true impact to the plant being interrupted with green?

Please fill anything that I missed that you are aware of.

Me either, because it seems unlikely it puts out a true green light. I assume all other spectrums are there, but it’s green biased and that’s what we see.
If I need to work after lights out, I simply use a dim light. Doesn’t appear to be an issue. Your grow may vary.

Nice break down of the various light spectra.
I use all of the wave lengths listed with good results.
I don’t work after lights out but have known a commercial grower that uses green lights for working during lights out. I agree with @Covertgrower on the issue of the green light purity.
