ppl helped me here u go

ac unit if u use one u need to account for the water if it is a window unit ........the water will smell like weed and tip dogs off .....to counter this plant hot peppers and strong smelling flowers like jasmine(best choice they use this to pack and smuggle) / lilac

as for the fan power u want to get yourself a 6 infan (cfm 400) and a controller for speed ............the scrubber u need to make that CFM it is 6''x16''.........6 inch ducting and some silver duting tape.........go to a home depot and get the ducting u do not want the rigided stuff u want to spend the extra money and get the flexible stuff

u got the lights covered ............order some auto plants they are easier for first timers .........start with soil grows sinnce they are more forgiving to mistakes then hydro
