i dont mean to offend...
honestly, i dont believe u have been reading about growing for 4 years. and no, u dont know what u r doing.
if your using co2, y do u want to have like 5 different rooms? why not have all the plants in one vegging room? u can still do perpetual harvest with that. just put them into the flower room at different times. theres absolutely no reason to do the room setup u mentioned.
and if your using T5's and LED's u WILL NOT get what u expect. especially with a 6 foot tall plant. the light just will not be good enough. go get 2 1000w HID lights. one blue spectrum for veg, one red spectrum for flower.
growing plants to full potential DOES NOT mean a huge plant. it all depends on your setup. if your growing with small CFL's, u dont want the plant to get too big, otherwise the light cannot penetrate through the foliage, and the weed that comes out of it will have weak potency. the same goes for all other lighting, they all have their limits. growing a 6 foot tall plant will not only take forever, but it will be a waste of time in your situation. it would be better to do two 3-4 foot plants, than one 6 foot tall plant.
why not go get clones? growing from seed not only takes longer, u have no idea what it is. u could grow the plant out to 4 feet tall, only to find out its a male when u start flowering.
i would recommend getting 2 clones. put them in the veg room. after they grow for a few weeks(1000w is kind of overkill for 2 plants though), cut 2 clones off of each plant. now put these clones in the veg room as well. u cut 2 clones incase one dies... so if they all survive and root good, kill off one of each strain. now u only have 2 clones, one of each strain, just like at the beginning.
once the original plants get big enough, throw them in the flower room. when the clones get big enough, cut clones off of them.
do u see how the perpetual works? it does not need more than 2 rooms. it would be a complete waste for u to do more than 2 rooms. considering the cost of lighting, co2, and convenience, its just not a good idea.
i dont mean to sound mean... i just want u to see
edit: actually, now that i think about it... 1000w is overkill. since u only have 2-4 plants in the room at a time, id go with 600w or 400w
