Oops my bad.. No SID in the mix = pretty much no Lag time... So you basically need 12 hours of equivalent SID. A PAD time factor of no higher then 1.66..

Once you think about it... There are many different Combinations to chose from...

The only problem I see right now. You are using an estimated time factor of 2 and an estimated time factor of 5.5 to get an estimated time factor of 5.2..... estimated x estimated = estimated... The good news is I think you overshot your estimated time factor and your plants will act more like a 11/13 type of flower. I think that gives you more (if you want) PAD on time...

Let's say your PAD time factor is actually around 4.2. Then you could run 10 hours of PAD 4/10/10
and you would have 12.3 SID

Now the question is can we get Sal to look at your PAD lighting you got posted and give his estimate on an estimated time factor.
