â???â?� : ventilating a C-24 close t: (-) pressure and how it benefits

[FRIENDinDEED]

I have decided to grow in a C-24 cab and figured Iâ??d start with the components of a closet first and then once I get the closet I can set everything up in it. So far I completed my DIY carbon scrubber and am currently going to wire my DIY cool tube, just have to drill a hole through the reducer/inducer for the connections, and am in the process of finding a cheap/er can-fan and I wanted to know:

-Can a blower be used in the same fashion as a can-fan regardless of CFM rating?

-Anything other than e-bay, that I can go to , to physically see a cheaper fan
*( NYC by the way)

*my scrubber is about 14� in length, 6 x 4 inducer/reducer, ¼� batting on inside around core and a layer on the outside so I have about 1- 1/4� of activated charcoal in there now, giving me about 10 or so inches of filtering space.

-What amount of CFM fan do I need to pull through the scrubber, past the bulb, past the ballast and to out take? With say about 9-10 feet of vent coil tubing.

-How many plants can fit in one of these C-24 cabs?

* I plan to seal the closet with weather stripping to create the negative pressure I have been reading about?

-What are the benefits if any of negative pressure environments for the plants?

Ofcourse all responses are appreciated, I am the same here as I am at the other sites I have subscribed to. This question has been posted elsewhere to get the maximum information possible. My name is the same as well at the other sites I speak of.

I have a double C24 and can put about 15 in there if kept under two FT and a low side branching strain. I think that you could go with 8, but 6 would be optamal IMO. The other questions you asked may depend on the light your using, I may of skipped it.

ok , since my last post I have been doing some serious searching and have pretty much found what I needed to know as far as the necessary amount of CFM I would need in a fan to pull through my carbon scrubber, around 200+ would be sufficient.

Q: Is there a significant difference between a blower and an inline/can (squirrel cage) fan? In regards to CFM, power can one do more or less than the other? I have read that it is kind of difficult to attach/ adapt a blower to an inducer/ reducer. Can a blower be used the same way an inline/ can fan can?

Thanks for all the replies, I really think that these are questions that may be added to a faq one day, so I am trying to gather as much info now as I possibly can pertaining to the specifics about fans , for all, especially the noobies to growing and set-up a closet.

***sorry it takes so long to reply/post. been busy searching, but i am trying to "blaze a trail" about this topic

***here is the closet/ dimensions i am talking about(on the bottom): http://www.millspride.com/assembleinstall/closet_specbook/wardrobe.htm

:jointsmile: Hey FriendinDeed
Yes there is difference between blower{squirrel cage}and can fans.The size of the blowers are much bigger than can fans.I 'am going with a 4" vortex fan in my cab that I'am building at this time.The 4" has 172 cfms and pulling air throught a 6" cool tube light and out the carbon filter.Air intake from two dark room vents at the bottom of the cab.Go to {plantlightinghrydroponics.com} they sell the vortex fans cheap ,a 4" fan runs around $110.00.The cheapest I have found so far.What kind of grow are you planing, flood&drain or drip or soil?Please keep us posted and I will do the same as I build my cab.I plan to start the build in a few weeks,right now I'am working on the details that go with it.Well thats my two:twocents:

CRAZYWILL: :D thanks so much for responding to my question(s).. :o i have been worried alot about the fan since i have a DIY carbon scrubber. mine "seems" like the ones you see online but it is kinda fat, so i am not shure how it measures up to the fans needed.

i too am building my components as i go, i want ot be able to just "put everything up" when i finally get the closet, i guess i will post pics then from the remote location, once my closet is up.

:jointsmile: gonna do a "promix" soilless type (DIY ofcourse) with organic nutes. :D trying to see if i cen get around the prices of the CO2 emitters as well.

my cool tube is a DIY out of a hurricane style vase. they are mainly used to cover large candles, open at the bottom (MICHEALS craft store, PIER-1, TARGET, etc.). i have had a hard time finding one long enough (one i have now is a inch longer than the bulb, think it could be longer) so i may have to just go ahead and cut the bottom off of a taller tubular vase.

:o trying to keep a VERY LOW "MAIL IT TO MY HOME/ ORDER OFF LINE" profile. most. already have my clone/ seed hook up so i got that out of the way as well.

:jointsmile: i am all about info trading so if there is anything i may help with just let me know since we are both pretty much at thebuilding stage. thanks for responding once again :o i can get a little obcessed with the whole "is this right " thing.
