Hey there cture, thanx, i hope i do good as well.Well as for the advantages there isn't many really, there is just the main big reason......."Stealth",,,,,,sure it isn't that stealth but how much can u really hide the fact that ur growing weed,not much, and this is the best i can come up with for the amount i want to produce.You could always go smaller but this is whats gonna work for me.I plan on having a seperate small but tall closet in which to keep a mother in and cut clones off her for the rubbermaid box.The thing is with this set-up i can easily just pull the plug and it's off and discreet,and just looks like 2 rubbermaid containers which everyone has stacked on top of each other, with the other ways of doing this i have seen guys put the 2 rubbermaids together without using the lids and it looks real suspicious, although that style can be hidden somewhere, with mine i have it right out in the open.You may also notice i have no filter or anti-smell device, this is not a problem for me either, seeing as my house is full of weed smoke anyways,but if it were a case of needing it hidden, like i said i just simply turn it off and if i had to, put a cover over the intake and exhaust.Anyways i feel as if i am rambling here (:stoned let me know if you wanna know anything else......Love peace and resin grease !!!
