16 plant grow room (plan)

Hello it took a while for me to do this so please give me your thoughts on how to improve this plan. I am also going to have 2 mother plants, i am going to take 8 cuttings off each mother plant. After they have rooted i will put them in a flowering cycle straight away. This is the plan of my flowering chamber.

Pretty sure it would be easier getting , or make 4 Hydroponic system . Your way is good but the tubes are in the way and under the lights . I wouldnt keep them under the lights

What CFM your 150cm fan can push? I don't know if a 6inch fan hooked to a carbon filter would be enough to keep the room cool with 4x 600w lights/ballast.

I would hook the carbon filter overhead in the middle of the 4 lights. I would also hook the ballast overhead near the filter.

Heres the fan it doesnt say the CFM i had a talk with the guy at the grow shop and he said if i had 4*600w lights i would need a 150mm. And i had looked at ebb and flow systems and they are wayy to expensive i just want something simple so i dont have to water the plants everyday.
