Growing Auto-Flower Strain and Photoperiod in Same Cabinet

High guys a little help, i'm curious as to how i should time these plants. I'm growing G-13 auto diesel and CH9 Toxic Blue 33. I'm using cfl's to veg and a 150wt hps to flower. The auto diesel is 70 days from seed to harvest and the toxic blue 33 is 25 - 35 days ved and about 2-months flowering time. Should i start em at the same time or what? I don't know how long it take for the auto diesel to start flowering and i don't want the lighting schedule to get all fucked up. Especially if the diesel flowers 1st while the toxic blue is still vegging. I was thinking of putting a divider in the middle but that would greatly restrict airflow. How does everyone else do this?

if you were to start them the same time, you would have to veg your photo strain for the amount of time it takes the auto to finish, 8-12 weeks depending on the life cycle.
so i would start the auto before hand , grow it for about 4-5 weeks and then crack your other seed and you should only have a few weeks left of the auto and you can veg your photo in that time.

Yea, I thought of that, but I wanted to veg the photo under cfl's. I guess i could have a mixed spectrum but if i were to do that then the auto would be running at 12/12 and the photo would be running at 18/6. Also I have a grow partner, We both paid for everything half n half but I let him have the diesel (bc of some early technical difficulties) and the photo is mine. So he'd have his weed a good while before me which would suck ass. Wouldn't it be better the other way around? Start the toxic blue, let that veg for like 10 days then start the auto?
