First time room setup, need opinion

So heres my situation. I have a 13ft x 71/2ft space dedicated to my room. I will be using reflective mylar as my walls. My question is what percentage of my room should i dedicate to flowering?

I would say at least half...you need more room to flower than you do to veg moms/clones...But it depends on how many plants you want to flower and how many moms/clones you want to veg. What lighting are you using?

veg I would do no more than 1/3 probally less. if you got a mother plant and growing from clone a 4x4 veg room will supply enough for a 4x8 flower room so up to an 8x8 if you veg 1 month flower 2 months. but you'll need a little extra space in your veg for 1-2 mothers and cloning.

if you dont have a plant limit then you could SOG almost all of it. Just have a small veg tent or side for your moms. AL B Fuct style.

Well im gonna have 12 going, 6 veg 6flower. I plan on using a 600w hps to veg and 1000w hps to flower.

Then I would grow bushes or trees. Or even Scrog. I would probbly have 2/3 be your flower and 1/3 be your veg. What kinda medium you running? What kind of strain?
