I don't know what to do.. Should I flower??

[offtheradar]

Ok, I have 18 plants in a homemade cabinet that is 10 ft x 5 ft and 8 feet tall with 2000 watt hps. One large bubbler and one large drip system. 14 of the plants are into the 6th week and already within 2 feet from the top of the cabinet. 4 plants are only 2 weeks old and still very small. I need to decide If I want to start flowering now as I'm probably going to run out of room very soon. I can't bend the plants because they are already so bushy that there is no room unless I have to remove the males soon and make room. Should I sacrafice the 4 new plants?? Strains are White Widow, Durban Poison, Sex, Island Lady and one plant from some bag weed I bought.

Sorry, I was wrong they are near the end of the 7th week.

Well, since no one answered my question and the only posts on here are mine, I did what I thought was best and sacraficed the 4 new plants and started 12 on 12 off for those interested...

sounds like your in trouble. Six weeks of vegging (18/6 or 24/7) is too long unless you have limitless room and height. Your plants will at least double in height when put into flowering (12/12). I would cut it down to no more than 4 feet high, or bend it over and tie down with string. I think you may have too many in your cabinet too. It's always better to have fewer plants with room to grow rather than many plants crammed into a small area. You will get the same yield or better with fewer plants and adequate space.
