Mother, my first responce to your comment was to think of stepping the spectrums at least at Nightfall, in order to hasten or delay the Nightfall process. After looking at last quarters pile of data, I'm still realling a bit and feeling sort of overwhelmed by it all. My rist has been laming my brain a bit lately to.

As per our question about using four cycles, it primarily has to do with changing the gene time used and/or the energy used for a duration or even a interval process.

For instance leaving the Blue signal on while while trimming one of the other spectrums here or there, reduces the energy input while maintain the Blue schedule unchanged. This would be more for energy concervation than reducing stem elongation in one such application.

Two of the flowerings I just went back and looked over had the same basic schedule that you just used, but they used less than half the energy to achieve the stem elongation slow down during pre- or early flower. In these two examples the number of cycles was not changed but the synchronizing between them was alterred to tune the plant percieved Darkness duration. The schedules were changed (minimally) 4 times, one for vegging, one for early flower, one for bloomiong and one for finishing/ripenning.

As far as suggestions, I can take you too far forward at the moment (I asked), but I can take you a bit laterally.

Although it results in a bit of subcanopy stem elongation, I would suggest that you consider using more Incandescent. Even if you used nothing but a regular clear Incandescent for your Blue signal, the increased tip elongation would provide you with enough new tip growth to observe the changes in morphology (leaf/flower formation) to know what the results of your Darkness schedule are, new growth wise.

Also during this preflower phase, you could reduce the amount of LED wattage used and still similar results, and if you are using Red Inc.'s during the Darknesss interval, reducing the Red LED wattage could give better results, but the timer would have to be reset to adjust to the gene clock speed increase.

I know what a shock the growth slow down can be, but if you can hold on till Halloween, I'm sure you will see what fruit this beastly thing ultimately bore.

Dog, I just reread you question about Reducing the Time Factors, sorry I didn't answer that one as I had thought.

To reduce the Time Factors lower than that of the Red Incandescents you're using, you can exchange one for a Incandescent Blacklight or even dim the Red Inc.'s. There are other options, but I'm limited in that direction at the moment. (Don't worry Dog, even you will have some surprises coming).

As always consider what changes in the timer might have to be made if you change the spectrum.

Personally-
Less than three months to go and I can't wait for some time to brain chill when it's over.

Some interesting news, I've been sellecting stock in my Low Haze breeding project, but now Rauber is calling it LED Haze since the seeds where bred using Rauber's methods and there are no current plans for using any other method for breeding the next generation, making this a LED bred strain. I should be making the next Inbred generation within a month. I'm hoping this will turn out to be a nice strain for LED, HPS and outdoor tests.

I hope that coverred it all.

Take care, Sal.
