much need info to help me on my grow

hello,im really in need of some advice regaurding my plants,i currently have 6 auto big devils that have been on a light cycle of 22/2 for approx 5 weeks,but along side them in the same grow room i have 2 normal photo period plants,1 lemon and 1 sour cream which are about 16inchs tall,they have been on the same light cycle as the autos,now im wondering if i want them to start to flower if it would be ok to take them out of the grow area when they have had 12 hours and put them in a dark seprate space for 12 hours then reintroduce them back to the grow room,is this ok as i want to trigger them to start flowering?and if so with them being veged for 5 weeks how many weeks should i flower them for?i really do need some advice,thanks....

if you want the non auto plants to flower, put them on a 12/12 cycle

ive never grown autoflower plants

how many weeks flowering would you say as they have been veged for 5 weeks?

depending on strain 8-13 weeks. just make sure all the hairs have mostly changed color, get a pocket scope(radio shack $13)and check the the trichs..you want mostly cloudy for a head high, and amber for couch lock

respect mate!!!
