Make sure to clean and disinfect the equipment... and I'd look at buying some of the soluables, Foxfarm's soluables, or Advanced, Humbolt make some, basically all the same, boosters for the flowering stage... like Beastie Budz, Big Bud, Overdrive chaching...
I definately recommend growing in a bigger container than a two-liter bottle, you could pull it off in a hydro setup, but that's not enough rooting room in my opinion, to have a decent harvest...
stay tuned for those pictures...
