yea man the ag is def. a fun thing to grow with, and it works very good. it just has limitations on growth i think. the reservoir is only a gallon just doesnt seem big enough to produce big time plants. but for yourself its really good i have nothing bad to say about it other then when your plants get big its hard to change the water. from what ive seen soil produces bugs, my buddy has them in his grow and i have none. and my ventilation is a 2 inch slot the entire bottom of the closet door, that gets the fresh air in. then i have a plastic door inside the closet, so then you have to open that after you open up the real door. then all the exhaust goes out the top through the scrubber.
i really have no smell problem unless i leave both doors open. if i do that my apartment quickly fills up with a nice skunky stench. other then that my set up has worked the balls. the whole reason i tried to make it smell proof is that i live above a restuarant and it gets a little sketchy at times. i kno the landlords real good(family) so i dont worry about them its just people down there i worry about. and so far i have no smell problems and inside the closet really stinks. so its all working as planned so far. and as far as my grow and my buddies, they were about the same height 2 weeks ago but he starting flowering a week earlier then me so his arent as tall as mine are now. he had some grow space size issues.
peace man
