Hi all, At the moment i am running a 4" extraction system that draws about 250m3/h. I have found a good deal on a 6 inch fan that will double that up to 500m3/h. I am wondering if i would be able to run the 6 inch fan with my 4 inch carbon filter using a ducting redactor. With the carbon filter only being a 4" how much of the 500m3/h will i lose? Is it worth it or just invest a bit more and get a new 6" carbon filter. The only thing is my 4" filter is brand new so i feel like its a bit of a waste if i can put it to use. Thanks

Got a budbox xxlr and my plants are growing like mad so I'm constantly pulling thr lights higher but now my filters in the way. Is it ok to place it on the floor? I'm still going to have the fan attached right next to it and then just run the ducting straight out the side. I know heat rises but right now were hitting colder months and I'm hoping a few fans just blowing the hot air around will suffice. 7

Hi, I've seen quite a few posts recently about saving head room in a tent, or not being able to lift the equipment to the top of the tent. It is often assumed that this is where the carbon filter must be located but there are other options, the fan & cf can even go outside the tent it necessary. I am in a wheelchair so had to opt for #4 in the below diagram with the fan & filter in a box on the floor (outside the tent) with a cushion underneath to dampen the vibrations/noise and it works a treat. Good negative pressure in the tent, no whiffs, job's a good 'un. (Fan blows air through filter). Hope this helps a few of you Tip: fully stretching out ducting reduces noise. Found this diagram on this forum but forget who posted it. If this is your picture, thank you

I've always bought Rhino but the latest is faulty - just been in back garden and its minging defo filter - checked everything else.. I found a thread recently that had a few people with the same problem with Rhino and a few people were recommending a different brand but I can't find the thread...

Just went up to the local grow shop to get a Mountain Air carbon filter after reading all the rave reviews on here. Stupidly didn't ring before hand and they didn't have the 150/500 in stock. They guy behind the counter was trying to tell me Phresh and Mountain Air filters are made by the same company, same spec, same Australian carbon etc.. I've got him to order me a Mountain Air anyway but wanted to know if there was any truth in this or was he just trying to sell me a filter there and then as I suspected!?

Morning all gonna take advantage of a black Friday discount a supplier is offering and upgrade my carbon filter. my rhino pro is at the end of it life well at least for the flower tent. Im set on getting a CarboAir as heard good reviews on them. question is which do you think would be the better choice 6inch 50mm bed 330mm length 6inch 50mm bed 660mm length 8inch 50mm bed 500mm (with reducer to 6inch) 6inch 60mm bed 660mm will be going into my 1.2 tent. Any experience with the different thickness bed of carbon? Im thinking best to go for the thicker but are they worth the extra money?!!

Welcome to my new thread which will be used to document my fun goings on down the back end of the garden for the remainder of this year. Current status: The Sweet Seeds competition has ended and I have a variety of plants in various stages, plus competition-winnings-seeds to germinate. A Cream Caramel clone who nearly died months ago, was waterlogged and took forever to root, the others were fine but this one I have nursed and nursed - Now she has rooted, taken off and I have topped her twice and had some bonsai type fun. I hope she will, in the end, bring nice large half metre long sticks of lush sticky buds: The Cream Caramel clones which did take off well, there were three, are well into flower, I think week 6 is now completed, could be week 7 I am unsure. There is also a single Cream Manderine which rooted well but its other 3 failed to take, so on the left side of my shed I have these four ladies: There are also four smaller Cream Caramel clones nestled in the middle of the shed between the larger Cream Caramels and my new Crystal Candy ladies which were sprouted from seed when I made the original clones. Here are the Crystal Candy ladies, I tried some LST but they were just unwieldy and two grew real high and fast for the sky Here is the largest bud forming up well: Since all of the above are a month from being cropped I have put on some new seeds, Sweet Cheese (on the left), Green Poison (middle row), Gorilla Girl (right side): Here they are in the tent, I had to take out one of the four legs to fit the box in as it is too big but with some black awning covering it - No light escapes. That's just a 125w CFL to keep them happy during night time. During the day the box is moved into the garden to get the best the sun has to offer That's where I am at right now. Fingers crossed ! So my setup is 2 x 400w Sylvania bulbs, not dual spectrum, brand new. Biobizz All Mix soil. Biobizz nutes: Grow, Bloom, Fishmix, TopMax, AlgaMic, RootJuice.

Hey Guys, just got a greenbox tent off Amazon, its 40 x 40 x 120. Been researching for the past few weeks for a quiet inline fan and good carbon filter for the tent for a small grow. Was trying to find one thats pretty quiet because its close to the room where I sleep. Theres a lot of mixed reviews out there of various fanned filter setups, I was hoping to get some opinions of what you guys think would work best for this tent size? thanks in advance!

Hey Guys, on the hunt for a really quiet inline fan and carbon filter to go with it. Tent is 60 x 60 x 140. Came across the cloud line t4 fan by ac infinity. Seems to have all this mad tech in it to make it really quiet and a unit that helps adjust the fan speed to match humidity and temperature. Will all this really make a difference or should i just go with a traditional unit and a variac controller? Now I've been adding up my costs for the tent, lights and fan and carbon filter...and my god is it getting expensive. the phresh carbon filters that everyone recommends on here are an additional 100 quid at least along with a good fan that's another 100. Tents are a ball ache to find a good one, fairly sorted on the light front but now im struggling to deal with getting good extraction for a decent price. really want something thats quiet as it will be in the house. Any recommendations guys?

Hi currently buying bits and bobs for my first grow il be using the dr60 (60x60x170cm) made my mind up on the light il be using the diyled scope-150. Just really stuck on what fan and filter to use want the best one to get rid of all smell and a fan thats not that noisy if possible moneys not really an issue just want the best one for the area im growing in. thanks

I have a 4" carbon filter which still has plenty of use in it. I'm thinking of upgrading my fan though as temperatures got dicey when I added more light in bloom last time and don't really want to fork out for another filter. Will a 6" fan (Can max-fan pro) make my 4" Rhino hobby filter die extremely quickly? Thanks all.

Hi all I posted a few weeks back, asking for some help and advice as my friend (@maverick40b) and I are getting set-up for our first grow, we got some good feedback across the various posts we put up and some great help along the way. It seems like this has now been going on for a while but we believe we are now very close. We have put together an itinerary of the equipment we have gone for and think is necessary to get everything setup. This is now our final step before committing and spending alot of money on this, we would appreciate any feedback and advice from you guys, what do you think of the list? have we forgotten anything? would you change anything? reasons for changing any equipment?

Hello again all. I scrapped my tent and decided to go for a small closet grow. The room is 2ft x 5ft x 8ft, with a 12 gallon pot under a 300w cfl. My carbon filter is suspended directly above the light and I've run insulated ducting through the wall, into another closet in another room and up into the loft, where I have my DIY box fan, then approx 4m run to a wall vent. The loft was the only place I could have the fan due to the vibrations and sound, I tried everything from wrapping it in insulation, acoustic ducting, suspending from rail etc but still too loud. My question is - would I be better venting into the loft space itself and letting the stale air naturally disperse (its a large loft with room to stand up and walk round in some places), or as is - directly to outside? I know my little light wont be putting out much heat but I was thinking with a copper chopper flyover on a cold day hot air gushing from my eves may be noticable? I've got some pictures but still unsure how to upload them? Thanks anybody who reads

Hello all and thanks for to admin for approving me. Excited to join the community after spending many hours reading up on several topics. I'm looking to start my first (small and low budget) grow and although as stated I have done quite a bit of research I'm getting some mixed information so would appreciate if anybody could point me in the right direction on a few things. I intend to grow only two plants to begin with, most likely some autoflower NL or Jack Herrer as I've read that these are short, easy to grow and less difficult to keep on top of smell wise than say Blue Cheese or White Widow. TENT Firstly, I have a tent 80cm x 80cm x 160cm that cost me next to nothing from Amazon. It has a couple of pinhole (and I mean a hairs breadth) that are sometimes visible through the zip - will this have any negative effect? This may sound silly, but I've stood inside it zipped up and I can't see jack, so I'm guessing it's nothing to worry about? LIGHTING I impulsively bought 2 £30 no-brand "216w Dual Spectrum LED UFO Grow lights" to go with it. I saw on Youtube that the actual draw of these lights is 65w but they apparently emit the same amount of light as a 216w HPS. The description is as follows - LIGHT SOURCE: 72 pieces of 3W LEDs, high lumens of 21,600LM, high power Par Value ensured, it is environmentally friendly. BLUE LIGHT: contributing to plant photosynthesis, promoting growth, protein synthesis and fruit development. RED LIGHT: promoting rhizome growth, blossoming and bearing fruit, extending flowering phase and increasing output. FULL SPECTRUM: wavelength of 410nm-730nm, white and warm white, providing natural light for various plants in different growth period. GREAT HEAT DISSIPATION: built in a cooling fan ensures great heat dissipation and long lifespan of 50,000 hours. After further research on these cheap no name LEDs I have come to the conclusion that this description is most likely bullshit. I stuck a couple of Komodo Dragon chilli seedlings in the tent a fortnight ago, to give the lights a test run and also to see if I could control temperature and humidity with the basic equipment I have. The fan in one of them is already bust and I'm going to return it. I don't hold much faith for the lifespan of the other one either and still have 20 days to return them both for a refund or replacement. Would I be best to get a refund, steer clear of these shitters and go with a CFL, perhaps a 300w as this would give me approx 50w per square foot? VENTILATION This is what I'm really struggling with . The tent is in a bedroom, which I spend most of my time (I live alone in a large upstairs flat and its cheaper for me to heat one room in the winter) and from what I've read, for me to effectively run exhausts and intakes outside would mean I'd need ridiculous lengths of ducting and stupidly high powered fans all over my place or start knocking holes in ceilings (which is a no). Is it okay to run intake and exhaust into a small tent from within one room? My tent is 35 cubic feet. I have a small duct booster that I intended to use for intake that is rated at 103/cfm. It's nice and quiet, low powered and didn't cost much. I'm looking to purchase an extractor and have found this formula on google to work out my needs - "To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet. Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM." By this theory I'd only need a fan with a rating of 11cfm which can't be right can it? After using another calculator on a Hydroponics store website they advised me that I would need a 200cfm fan with a 300mm carbon filter. Does this sound more realistic? Also I've read that the restrictive effect of the filter will deduct 20% from the CFM rating of the fan which would only give me 160cfm, which I'm guessing won't be enough with my 103cfm intake to maintain negative pressure. This shit is baffling me. Would I be better to buy a 200cfm extractor and filter, open up all the vents for a passive intake? Would that mean I'd have to run the extractor fan non stop night and day, or would I have to do that anyway? I'm guessing so if I need to maintain negative pressure. Carbon filters - After much reading I pretty much get the jist that Phresh, Can etc are the dogs bollocks and the cheap £20ers are not worth a wank, even that the Rhino Pro's arent 100% in odor control. I've learned from my experience with the lights that there is a lot of shit out there and skimping can be a false economy but my budget is seriously tight. Can anybody tell me from experience if some of the cheaper but branded filters like OX, RAM, Rhino hobby, Swiftair etc actually do the job (even for 6 months) of removing the odor. Like I've said I'm not talking about a warehouse full of prize winning Cheese here, just two plants. I also know there is the DIY option, I'm pretty handy but I would be pretty pissed off if I spent the time and effort making something that is no better than a £30 jobby I could have ordered from the bay. I've found a site selling Rhino Pro's starting at £35 so I'm edging towards this, but the skimper in me says to try a cheap nasty £45 full kit with a fan from ebay. After all they've sold over 1500 with mostly positive feedback. Thanks in advance to anybody that reads this and can give me any tips, hope I've not put you to sleep. BN

Hello all, Still new to growing so looking for abit of advice. I don't have much height in my grow tent, limited to 170cm. This run I witnessed massive stretch and the plants got quite close to the lights. I couldn't raise the lights any higher due to my carbon filter being in the way. It's a loft tent so thereunto much space at all above the lights because of the angled roof... The only way I can move the lights higher is to somehow re-arrange where my filter is sat. There's definitely no extra space above or around the lights. Where the filter is now is the only place it fits...Ive seen grow rooms with filters on the floor, so I was after people opinions on this. Is this somethiythat you lot would suggest doing in my position?

Hi guys. I need some help so I have a couple of questions. I’m going to build a small grow room (scrog) 55 cm x 55 cm x 120 cm (height). This is the calculations I did for the fan: 55 cm x 55 cm x 120 cm = 1.80 x 1.80 x 3,93 (feet) x 3-4 = 38,19 - 50,93 CFM = 86 m3/hour I guess my fan needs to have a higher cm/m/hour than that. I have been looking at this fan: I am going to be using a variac speed controller. I think I want to use the fan at 40 % of its max speed, in order to make it more quiet. http://www.onestopgrowshop.co.uk/fans-filters-and-air-control/duct-fans/systemair-rvk-5-inch-125mm-l1-in-line-duct-fan-341m3-hr.html : 323m3/h or 190 cfm. 40 % speed = 129 m3/h or 76 cfm. I have also been looking at the Ruck (can fan) and rhino fan. My first questions is, how powerful should my fan be for this grow room? Is this okay: 129 m3/h or 76 cfm? How much higher can a fans m3/h/CFM rating be than what the grow room needs as a minimum? My grow room is not that big, but I think I would be able to fit that fan inside of the grow room. I am going to put it in a box like this: https://www.icmag.com/ic/showthread.php?t=229614 (of course not as big) and then use oversized insulated ducting. The lights I’m going to use will be something like this: http://timbergrowlights.com/200-watt-cree-cxb3590-4-cob-grow-light-kit/ (DIY by following a guide) What size of carbon filter should I use for this grow room? My grow room is not that big, so I hope I will be able to fit everything in it. Should the carbon filters cfm/m3/hr rating be higher or lower than the fans cfm/m3/hr rating? I hope you are able to understand my English J Stiggy123, Denmark

Hi, Could you recommend a size fan/filter for a 1.2m x1.2m x 2m grow tent indoors in spear bedroom with 1 VIPARSPECTRA 900W LED light in tent? Soil grow,hand watering,autoflower,easy access to tent at all times. Was thinking maybe 5" would do it as LED light is half the heat of conventional grow lighting? Was also looking at purchasing the 600mm carbon filter but don't want to jeopardise noise? Noise and odours are unwanted so your recommendations/guidance would be greatly appreciated👍 Thank you

Happy 4/20 peeps! Hope everyone's having a blazy day! I have a large CF that was bought about 7 years ago and never used ... (larger diameter than my fan). It has been stored in various different places not all of them dry or free of odor. I read somewhere that the carbon will just suck up bad smells even without a filter pulling through it and as I say its ben lying around for years in damp smelly places. Basically I want to know if I can still use the carbon from it to re-fill my other filters as money is very much an object and the house is starting to stink! Cheers fam Happy 4/20 MM
