13ft by 13ft by 8ft grow room setup

I have a 13ft by 13ft by 8ft grow room.

Also 9 600W lights, all are air-cooled.
Also Carbon filter installed plus CO2

Using 2.5gallon pots with soil.

How many plants can could be the best quantity to have and how tall would be the best to let them veg?

My goal is to get the most yield out of it.

Thanks in advance.

2.5 gallons is to little for the size of the room u have ...................2.5 gallons of soil is 2 and half months of power(goodies inthe soil) after that the plant will be complete depent on your feedings for life ..........u should increase this if u are doing bigger yeilds strains or longer grows .............other wise u will paying out ass in feeding the plants to keep them alive along with maxium yeilds

your lights are air cool tubes good now u need to make a grid lay out for the lights and the ducing and start figuring on the amount of ducting inline fans and booster fans needed to keep the room cool ...............i am currently running 2 600 watts on only one 400 cfm fan it has little issuse so i added in a 240 intake worked out fine

if u are new at this do not except to have massive yeilds untill u learn about feedings and soils this takes time each planting u do the yeild and str will increase do to your talnets and understanding

if u are tring to turn around and recoop some of the cost of starting up and still learning ............look in to auto flowering plants 60 to 90 day turn arounds this will allow u to run several strains at once and get the results u like ...........short ones that give u a once a plant to larger ones that give u up to 400 grams

u will not get the 400 grams but u can safely figure atleast a QP to HP off each plant for new growers .......................now do not cram the room with plants u will have alot of trouble feeding and trimming go with something where each plant gets 2 square feet for each plant (for the 400 grammers ones) the once ones they only need about 1.5 feet ...............this is all untrained un scroged planting
