When should I switch to 12-12

I am starting a new Aeroponics grow 1st time with this system. It looks like I can let my girls grow to approximately 40 inches and maintain about 1 ft. clearance from light. I am growing Lambs breath(lambsbread), Green Crack, Hash Breath, and Blueberry. 3 of each. My question is how tall should I let them get before switching to 12-12? I know these may not be compatable strains, but kinda forced to use them as they were the only ones I had enough of to fill my system. ( Stinkbud's system)

Variety is the spice of life!
I Love your collection.
I would guess 2 and half feet would be your finished height so the timing may vary slightly.
Do you have a second spot to Flower?
Then you can let each plant veg to its own maturity.
I am a Noob so let a more knowledgable person chime in.

Switch to flowering when they are half the size u want the finshed product! ! So if u ultimately got 40 inches of space to work with veg till they hit 18 just to be on the safe side and switch them over to 12 /12
