Topping and training tips that fulfill a imaginary grow room of...

3 600w lights; 13ft by 4 ft, 8 ft tall room. growing 4 plants - 1 soil in a 7 gallon pot, and 3 in a RDWC system of 5 gallon buckets. How to fullfil the grow room completely and maximize growing potential and yield. The soil was put in there after the plan due to it being fem so it doesn't exactly fit the original plan. At the end of the grow, hope for them to be 7 ft tall, and 3 ft wide covering the area of the room completely... I need training advice as this is my first.

That wont work , 7 ft tall plants will only have buds about 2 foot from the top, the rest will be all stems a nd popcorn. better off with 4ftx 4 ft plants or sea of green.
