Dilema...

I have 4 Pot of Gold plants going in a 10gl DWC tub from seed. They are around 33 days old in vegetative state with 15/8 lighting. Everything is healthy, but they haven't shown preflowers yet. Last time I grew this strain in soil they showed preflowers after 3 weeks. I want to have at least 2 plants that are female so that I can clone and fill up my bigger 18 site aero tubs. I have already taken 9 clones from each plant (36 total) and they are a couple days into rooting. Problem is I am under a timeline...I need to have this grow complete by Dec. 20th before I go on vacation.

I'm wondering if I should take 36 more clones and switch the 4 plants to 12/12 or if I should just be patient and wait. I did number the plants and corrosponding clones so there is no mixup when they do show sex. Anything I can do to speed this process up or any suggestions on what to do? What would you do?

if ya got room take your clones and number em or put your babies into flower and as soon as they show sex take clones from lower branches or take clones and put em streight to flowering or ???? um thats all i got but yea you should be able to start flowering and get em to show in like a week or 2 you should be cool cuttin it close maybe but cool actually i have found that if you switch to hps and flower nutes a week before 12\12 they show sex faster but you don't have that kinda time i guess so i would just flower
