if your looking at the filters keep in mind you still need a blower to hook them to.i made my filter it has a duct booster fan on it and the whole thing only cost like $100 here is a pic of it
what light did you get? the light is going to be a big factor in your yield.if you have not started yet i swear the 100% perlite in a hempy bucket is better than a soil grow.you can get a light that has a switch that will do mh or hps bulbs thats how my light is.for air smell you have a while...
i have a bag of the walmart mg perlite right here it says nitrogen .04%, phosphate .01% , potash .06%,,thats the mg ..i use it just as it is because its so little amount but you can rinse it first if you want to
if you plan on doing more then 2 plants in the future this is a way better deal its a few $ more but comes with a timer and yo yo hangers.but its twice the light for the same price and you can cool it with a cheep duct booster fan,if you need to.any...
ok..for your light the Mini Sun 400 HPS (50,000 lumens) is only a few $ more and is a lot better light(EDIT SEE MY NEXT POST I FOUND A BETTER DEAL). the miracle grow perlite from walmart is fine it has a very small amount of nutes in it .(its only .1% total) so it has no effect thats what i use...
if this is your first grow and you want to keep it cheep and easy do hempy buckets get a plastic mop bucket($2) and a bag of perlite($4) from walmart .put a small hole 2 inches from the bottom of the bucket fill it with perlite and put your plant in it .its easier and better then soil grow trust...
i would do hydro or hempy buckets with a 600w mh and 2 1000w hps an 8 x 10 room is good to bud in with both 1000 wattters and a 6x8 or 8x8 to veg with the 600w. .big bud or anything mixed with big bud gets you a lot of weight per plant.but i'd like to smoke white rhino mixed with bigbud .
new pics my soil plants are flowering and my hempy buckets are still veggin after doing both i will not be doing soil ever again hempy buckets are better and easier in every way. walmart has a square 3 gallon plastic mop bucket for $2 and a bag of perlite for $4 so $6 and a light your ready .

your yield depends on a lot of things,light, nutes, strain,and more but here is a calculator i've heard its good but it can't always be 100% right, but it may give you a good idea http://www.angelfire.com/cantina/fourtwenty/yor/yieldcalc.htm
