Ballpark in a perfect world.. 8 weeks 18/6 veg, 10 weeks 12/12 flower.
By the way, 18/6 won't flower unless you were smoking seeded lowryders. Brickweed schwag or mids could be anything at all. Brickweed where I am is usually Mexican Sativa straight from Mexico. Mids are usually BC Big Bud (Beasters or Cannugget, on the street). Kind in my region is almost always a Diesel or Kush.
My advice to you is this.. veg (18/6 light cycle) until you move. Veg usually doesn't smell (unless you have something pungent as hell like a Diesel), so veg. them out for the 2 months and when you get to your new place, 12/12 immediately. You'll start seeing flowers in 1-3 weeks, then 8-14 weeks (depends on genetics) flowering.
Your lights are perfect for veg. They will suck ass for flowering, though, which is what you REALLY want. Replace all those with 2700K or less cfl's when you go to 12/12. Also, if it's from brick, you will definitely want to read up on LST, as your plants could get mammoth fast. My first indoor plant was like 4' high in a month. That's tough to deal with. LST will allow you to fit your plants in a much tighter space.
Luck, bro. Also, check my grow if you want to see more about CFL. I'm running 2 computer cases.. one veg., one flower.
