lighting question

Alright so im going to be ordering my grow stuff in like 2 weeks. Im going to be using 200 actual watts of cfls 14,300 lumens and be growing Nirvana northern lights auto and i might get bubbilicious auto to. But could i run 18/6 since im using a fuck load of light for one plant and get a good yield like 1 1/2-2 ozs and northern lights is a big yielder

Grower you shouldn't have a problem to get a 1 1/2oz with those lights, on my first grow I was using two 125w actual watts cfls and some T5 for side lightning and I pulled 3.6oz from two plant's one was Diesiel Ryder from Joint Dr, and the other one was NL Automatic from G13 I got around 57g from that NL Auto.
But it also depends on the genetics of the plant, set-up, ventilation, all kinds of stuff is going into consideration but I think you should be fine with those lights and reach your goal of 1 1/2oz

Good luck on your grow.
