Only 1 homebox L ,Moms and Clones ?

hello to all forum

it is my first grow.

i will buy a homebox L in 1 week.i have bought almost everything.but there is a big problem:

first, i have ONLY one growbox (that is homebox L ).In addition, i have 10 seeds.now my question:

i will grow my all seeds and i will have for example 7 female plants(and 3 male plants).i will have no seeds anymore.i want to continue always growing all the time without seeds.(i want to grow only using female clones )

that is why,i must do clones when my plants going to flowering (to see which ones female )
but it is problem:
i have only one growbox.and when i take clones from my main plants,main plants would be in flowering cycle(12 hours lights ).but my clones would need 24 hours lights (vegging period ).
and I have ONLY one grow box.

what can i do to keep on growing using clones without no more seeds ?

and remember,i have only one growbox .

thank you all.

Sorry dude you're screwed. You're trying to do something without enough equipment. You have to get a seperate growing area.. Last thing you want is to screw up while in 12/12

Well, is a microbox enough for me(eg 50cm x 50cm x 50 cm ) ?
or do i need a homebox L more ?
