this is what i was thinking, tell me if you would alter it and how?

i wanted to smooth out the ground best i could and have 10 planter boxes built out of wood that are raised up enough to drain and for the water tubs

i was thinking of doing soil and having around 60 or so plants down each row

i was going to do a spray system attached right over the planters with clear plastic or not clear if i want to direct the light right down on them?

the plastic would sit inside the planters so if it hits the side it will still be directed down to the soil to the plants

i would make a drain system underneath that directs outside

i was thinking of starting with seeds, feminized of coarse, and try 6 different quick growing strains but yield high. i have read that white widow is a good one and low ryder as well, again suggestions are welcome!

now i have watched the dr. green thumb videos and i know about cloning and the chemicals and all that. do i have to use CO2 and what is the major benefit and loss if i don't use it?

i would like to have harvestable herb every 6 months, is this possible?

feel free to give thoughts on that set up!
