First attempt at a 24-hour "Martian Method"

[Mother]

Lets start here. How come SOD with far red is not the same time factor as SID with the same amount of far red. How come they are different? let's say the time we are measuring in both (SOD) and (SID) is 12 hours for this example.

Hey Dog, I think you might have just read it wrong...

SOD by default already includes Far Red. SID does not. It is the Far Red, and only the Far Red that makes the difference in the time rates between the two. So, a given length of SOD will be exactly equivalent to the same length of SID if the SID has the same exact amount of Far Red added in.

How did we flower with an (AD) time factor of 11/2 ? ......With alot less blue or no..

I think you're dividing total AD time (11) by total SID time (2), which is not the number you're looking for.
What you need to do is divide the total amount of AD time by the amount of SID time that you're trying to make up.

You need a total of 12 hours of SID or "SID-equivalent work".
If you were running 11 hours of AD time and 2 hours of SID. Subtract the two hours of SID that you already have from the 12 total that you need, and that gives you 10 hours of "SID-equivalent work" that needs to be done by your 11 hours of AD time. So:

11/10 = 1.1

So your spectrum needed to be 1.1 or less, and since you were running RedInc only, you may have been close, because RedInc is fast, and faster means a relatively lower time factor. Remember that Sal said (paraphrasing) "RedInc light is fast, but still not as fast as SID". Which means RedInc light has a factor something larger than 1, but not that much larger. Since you had success with it when you needed light with a factor of 1.1 or less, that seems reasonable that it worked out for you. But since your plants didn't like it indefinitely, the real factor for RedInc is probably larger than 1.1. More data, Dog! Awesome!

If plants outside are running .8 x faster then indoors. How do we speed up our indoor plants .8 to match outdoors.

If you wanted to simply match outdoors, you'd just have to add Far Red (only!) at the same rate as it occurs outdoors (and I have no idea what rate that is). Make sense?

I also realized that none of this takes into account light intensity, and I don't know how that affects the whole relationship. Oy!
