new grow box setup

i have a new setup it is a 3x3x4 ft tall box. and i have 8 plants in it with 11 23watt=100 watt clf bulbs and one fluro tube i am wondering if i put some lights lower on my plants so that light hits the lower buds to.
because i have all my light is just on the tops of my plants and the only light that is hitting the lower buds is the light that gets that far so if i where to put like 4 more 100 watt clf's lower on the buds will this increase my yield at the end.

now is it true that when you are using clf the more light the better.

can someone help me with this question

you have the right idea, the more coverage you get the higher yield. these 11 plants you have aren't sexed yet?

this is my lay out and does this seem good or bad

sorry about the shitty drawing

yes all 9 of them are females and they are now 4 weeks into flowering

it might be easier to get a hps bulb. do you have ventilation going or just fan in your box? as far as hanging bulbs you can and it will help though. if you can make there location adjustable you can work it around your colas too

i am going to stick with the clf they are working good. i think i just need more bulbs so the plants get more light i think i might just add like 6-8 bulbs so i have 20 clf's over 9 plants.

how long is the growth stunted when u transplant.
