with that much space how many plant can i get away with in there with long planters and walkways between them?

i see a few pics on that page you sent me to and it looks like that guy has a bunch clustered and packed in so can i do that as well...

is there a space limit for different strains, i would need to know that before i could build the appropriate planter to put them in. i was thinking rows of 30 and two side by side with about a half to a full foot between them?

so like around 60ft X 3ft planters and do like maybe 10 of them in that area

off the ground like 3ft with drainage that takes it outside

drip system above or i was thinking a mist system

thoughts on how that set up would do?
