i got mine from htg supply. http://www.htgsupply.com i had 12 girls like 5 ft tall indoors and holy fuck did that smell before and at harvest. carbon filter helps a lot. my main concern was thieves cause i dont grow in the house i live at. seriously them bastards will risk breaking into your house. wish they would try breaking into my house i live at so i could legally shoot them.
no problem. i got almost all of my equipment for that site. i spent over a $1000 but was by far worth it. i highly recommend everyone to check them out. they can be pricey but you get what you pay for. their customers service is also top notch. one thing though is you need some kind of exhaust fan to pull air thru that filter, and they are sorta noisey. you can get mufflers for them, but overall it can get pricey. this is what i got http://htgsupply.com/viewproduct.asp?productID=52531 i didnt get a muffler but if the noise is an issue you may want one unless you can get a quieter fan. its really not that loud and is not an annoying sound. but it may draw attention to your parents. its about as loud as a newly installed bathroom exhaust fan. my grow area 56''x56''x78'' its a tent from the same site. http://htgsupply.com/viewproduct.asp?productID=51335 i got excellent results my first indoor grow but i also use a 400 watt mh and hps. check my grow journal if interested.
