New Grower Lighting Cycle Change Question

[wbojb]

I have a question regarding my auto grow. I am 36 days in and have a Pakistan Ryder which is flowing as it should under 20/4 light. Also in the same tent I have two Kannabia "auto" strains, Hobbit and Mikromachine. I moved the Hobbit into my 2x2 tent for 12/12 because it would not get past preflower stage (no swelling).
However my Mikromachine is just past preflower with some slight swelling but still some minor verticle growth. I need to kickstart it into a full flower mode, but I dont have any more room in the 2x2 with the Hobbit.
My question is, how much can I lower the light on hours without hurting the Pakistan Ryder to help the Mikro along?
Thanks for the help!

But I wouldn't go under 16/8. I've done auto's under 12/12, but it just seemed to me that they lost potency. The stain I did under 12/12 I did under 20/4 several months back and the seed were from the same pac and all. It, under 20/4 was more potent...But then again, some auto strains do better under 12/12 than others. So see what happens...

I would give that Mikro another week before doing anything. A lot of strains will go a full 6 weeks before going into full flower. If you're still getting vertical growth it's not done with pre flower yet.
