Jilly Bean from seed questions

Im gonna be starting my first outdoor grow and its also going to be my first time working with seeds rather than clones. I plan on starting 10 seeds and im hoping for 6 females... if i dont get 6 ill just take a few clones to complete my 6 plant limit. Anyway, my questions were:
A: when growing from seed what is the soonest i can safely bend my stems to use the "supercropping technique"
B: when should i top them? doesnt seem right to pinch them before they show sex...

everything ive read tells me stressing the plants will decrease the amount of female plants i get.... but id rather not let them grow straight for the sky as i would like to keep them as low profile as possible. any answers will be greatly appreciated
-thanks alot

You should get your 6 ladies. TGA has always given me a high female ratio. You can start topping and supercropping at the second node if you like. I always top at the 2nd to take a cut, then force flower the seed. With tga I think my average has been around 70-80% females. My last run of 30 qleaners from seed gave me 24 females and made it very difficult to pick keepers. You picked a great strain for outdoors btw, and good luck!
