Ventilation options

[Nath]

Just wanted to know if my only option for ventilating an area would be a centrifugal fan and carbon filter.. I was looking at these:

 

150mm fan - 15m3 per minute - $225

150mm x 400mm carbon filter - $210

 

Can I use an inline 200cm fan for like $150+ which pushes the same air but quieter.. and my own home made carbon filter with much success? Ill be using one 600w HPS so far... after this crop ill buy new equipment, so it just needs to be able to get a crop flowered.

in short, no

honestly, while those fans kick arse, you can get away with being pretty cheap and using those ceiling exhaust fans for bathrooms which only cost $20 a piece the only problem i see with this grow is that its summer and you are using a 600watt light which is going to put out an extreme amount of heat :thumbdown IMO your best option if you have the money to spare is to buy an airconditioner....while they are expensive, look in papers and on ebay and you should be able to pick one up for the $150 you were going to spend on a single fan and it would help cool the room alot better than anything else :thumbsup

 

personally, if i were in your position i would really look into air conditioning, your plants will grow like crazy thanks to the reduced humidity + it'll keep the temps under controll. I would also look at getting those $20 fans from a hardware store + some ducting so you can run the extraction through the carbon filter...will be alot cheaper than those expensive fans thats for sure + if you only have fans sucking air out, you create a negative pressure so you dont get smell leaks :smoke

 

some other people will reply with better posts that are more helpfull without a doubt but dont hesitate to give us the specs of your system and what you intend on doing with it because it'll make it alot easier to help you out :smoke

I got a bonair watercooler for the room... and in sydney i was growing with a 600w light and 250mm exhaust fan and got mould as soon as I put in the mylar when the buds started forming, it was pretty humid in there. At the moment all I have is one 600w HPS lamp, the water cooler.. lots of 40L tubs for DWC, nutes, panda film, seeds, pumps.. etc thats all I can think of.. there will be the bits and pieces that make it hard for me but its generally nearly all there..

 

My main problem is smell.. Ill probably grow in a bedroom with one light or try to section it off but its easier converting the whole room. Since the watercooler is square its hard to blow it into a room sucking cold air through it and maintaining a seal so smell doesnt get out.. thats why I was just gonna run it on low inside the room to keep temps ok. Then Id just change the door so I can cut holes in it and make it into two sections and have all the exhaust air going out the top half of the door, and the passive intake vent on the lower half of the door. I want to go cheap, it would make things alot easier for me.. but I also want to limit smell, since the place I can only really afford to move into will be an apartment with lots of dodgy people around to smell my lovely plants.

Just pulled the back off it its a Bonaire Maxicooler Snowgum, it has a 35cm fan in it and I could attach ducting to the back of it.. but it would lose its evaporative cooling effect.. but it would still be a wicked fan to use.. taking into considerating after this first crop ill be buying a new fan and equipment for a larger grow. But my main problem as I said is smell.. but I guess I could make a square panel carbon filter to sit over the top of that square front of the cooler and glue it on someone to it and just use the fan to suck air out from the room and blow it into the apartment through the carbon filter. Just seems a bit dodgy, I really dont want to risk it in the sake of a few dollars. But those few dollars can go towards me getting a better apartment or maybe even a cheapo crappy house somewhere in the ghetto. Theres no problems with me getting jacked, just problems with LEO.

Have you thought about a dehumidifier, have seen some cheap ones on ebay, could do the trick? I wouldn't be running a lot of ducting on a house type exhaust fan, it can put a lot of load on then and they can burn out It may be if finances are available to pay a bit more and get one rated for continuous use, still shouldn't use too long duct, if you want to run a lot of ducting (fresh air etc) you should use a fan designed for that purpose

Thanks for the link, looks like Ill definately be making my own.. I guess Ill just pay for a decent fan.. I really wanted to get an inline fan though because of the price they are $100 cheaper and quieter compared to the centrifugal type, and I wont be running much ducting.

[dsyfer]

Inline will work, your talking the round ball type?

this style:

Yeah that is what those type are made for, running in ducting.
