  1. Hi everyone, If any gardeners have opinions on the following I'd be grateful for your input I'm getting the kit together for a small grow ... so far have bought a DS60 (60 x 60 x 150) and a HLG 135 w 3000k from diyled so now concentrating on getting the right exhaust and filter ... I've looked at rvk kits and variac controllers ... thermostatic rhino fans... and td silent fans .. but have 99% settled on getting the following fan ... Phresh 6-Inch HyperFan (535 m3/hr) The size seems good (150mm by 300mm) for fitting into my DS60 and hopefully is powerful enough to be run on a low setting.. it also comes with a controller ..I read somewhere that there is a slight high frequency sound associated with the fan but hopefully i can live with that . I'm thinking I could wrap it in acoustic material when it's in place (I'd like everything inside the tent ideally) The filter i'm considering (PHRESH SKINNY LOW PRO FILTER 150 mm x 300 mm (300m3/hr)) is same make and same diameter. I've read that it can be good to go up a size with the filter compared to the fan to reduce noise however this fan is rated with more flow than the filter ... but I intend to have the fan set quite low . and Hoping it will work with passive intake . tent will be in an unheated garage for a period ... maybe a year .. then in the future will be moved into an old water tank cupboard upstairs . in the garage i'll just be recycling air in the garage , although fresh air does circulated to some extent because of gaps in doors etc . then when the tent is in the cupboard ill run acoustic ducting up into the loft (less than a metre straight up) thanks
  2. 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.
  3. Hello! I have recently purchased this Variac: https://www.sentera.eu/Product/Details/eng/108450/230-VAC-transformer-fan-speed-controller-15-A and this extraction fan: https://www.amazon.co.uk/XFLO100S-Inline-Bathroom-Extractor-Standard/dp/B01GCG35RA Despite reading the mounting instruction, I have literally no idea on what to do to connect the Variac to my fan. I have tried searching on the forum but I am not able to find a step-by-step guide for newbies like me. This is the last problem I need to solve before starting my grow, so I would really appreciate if someone who's got a similar setup could help me out. There's nothing on Youtube and can't seem to find anything that explains the mounting for a complete electricity illiterate. Thanks in advance guys.
  4. Hello! I am new to this forum and I'm about to start growing some plants. The main problem I have so far is that I bought a 'Variispeed Fan Speed Controller' to regulate my extractor fan speed, however, it makes a very loud electrical hum when I slow down the fan. Is there any other solution I can use that doesn't produce that hum? I've read about Variac, but it's very expensive for me at the moment. Are there any cheap solutions out there? Thanks in advance and sorry about my English (not my native tongue).
  5. Hi guys, After a bit of advice! Currently running a 6" system air rvk and it's a bit too noisey for my liking. Even turned down on a controller. After a bit of googling I've come across the Phresh Hyper fan stealth. Watched a YouTube review and looks pretty impressive. Any users on here that can shed any light on these fans or if there's better available I'd love to hear your suggestions please! Also been looking at the filter silencers for extra stealth. Would this be compatable and again any users out there? Are they worth using? And finally do you think it would be worth upgrading all my 6" to 8" so I could run it even lower therefore reducing the sound even more.. Would this work? Any help would be much appreciated!
  6. I guys I’m planning on buying some sort of controller to help maintain the temp in my tent. I’ve got a 600w hps. A 150w extraction fan in 6 inch duct. And a 2kw heater outside the tent. Any suggestions on best set up to maintain temp? Thanks
  7. 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

  11. 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
  12. How can I silence my extraction fan it is a 4" extractor fan running at 185m3/hour air movement in a 1.2x0.6x0.6 tent. It sounds like a boeing jet engine and the missus wont have i on when shes trying to go to sleep in the bedroom. Thanks Here is a pic
  13. I have posted a similar question before but was hoping it may been seen by more people who can help in this catagory. Going against the correct advice given here not to buy a complete set up, I did buy a complete set up. I wish now I had listened to the advice and not bought it. The equipment is all very well made but the 250w with 250w ballast HPS light is too hot for a tiny 50x50x100cm tent where I will be growing one plant. After setting it all up and leaving a thermometer inside I left the light and outlet fan on for an hour or so and the temperature rose to 35c/95f. I think this is too hot for what I need. After reading about how to cool things down I bought a 6 inch desk fan which has done nothing to cool the tent down. The ballast is on a shelf outside and above the tent and I have a 5" extraction fan. I thought of buying a lesser wattage bulb (maybe 150w) but it will not be compatible with the 250w ballast. It is strange as it's been very cold and the room/cupboard where the tent is kept has a temperature of 15c/60f. I am at a loss especially as the people where I bought the kit from are very unhelpful. Should I sell everything and start afresh listening to the advice i've been given on this forum or does anyone know other ways to cool the tent down?

  15. Hello grow chums. I decided that my 5"ruck was very loud and decided to put a sock in it quite literally. After looking around the forum I found that many people had exactly the same complaint and it seem to be popularly known as "WHOOSHING". There are many how to's on the DIY section addressing noisy fans however none are quite like mine. First you'll need some of this, it's that foam exercise mat stuff You'll also need this, it's the cover from your fan, and some tape preferably the stuff that doesn't come unstuck in humid conditions. Plastic netting, chicken wire would very probably also do. Wrap the mat in the netting ,making sure that it will fit easily around the filter cover then cable tie it shut. Make 3x these, and place one at either end and in the middle to prevent a collapse of the filter cover lining. As it nearing Christmas I've decided to cover the whole thing in bacofoil thus! Now, I was fortunate to have a 5-6" reducer lying around however, all you need to do is pull the ducting attached to your fan inside the unit and tape it up vigorously and generously. For very little spent you'll be amazed at how quiet it is with the whooshing minimised, hope this helps someone ,or anybody!
  16. Hi everyone & Seasons greetings ... Just a random question that I wanted to get some advice on ... First time grower here .. grow cabinet set up ... plants in early veg stage and everything is looking great. Im using a 6"Hyper fan for air extraction with a speed controller ...im running the fan 24 hours a day , 7 days a week ... ? Im just wondering if this is a good idea ... or is it advisable to switch it off for a few hours a day just to let it cool down / take a rest. I know obviously there would be issues with not creating negative pressure etc It doesnt over heat and runs very smoothly .. im just a bit paranoid the following ... a) breaking it. b) over heating - a risk of burn out - and starting a fire in my flat .. when im not there. Just wanted to guage other peoples opionions and experiences Cheers Bigbird
  17. Could an owner of a Phresh hyper fan or the Phresh HyperFan Hyper Climate Controller please open the controller and take some detail photos of what is inside please. I am interested to find out if the controller is just a potentiometer or if it is sending a pwm signal to the fan motor drivers. If anyone has one of the Climate Controllers please could you do a review as I have not seen one before and info is difficult to come by. Many thanks
  18. Good evening, I have a question that I could do with some help answering. I have a 1.2 x 1.2 x 2m tent, currently running a 6" extraction (500 cubic meter an hour I think) I have one of the passive intake pannels off. Temps are stable. Tomorrow I will be getting a second light 600w, givingme a ppossible 1000w to play with, 1 x 400, 1 x 600. I have a 6/inch can fan for the extraction upgrade and this will move about 720 cubic meters an hour. My question is should I remove the second vent pannels on the tent,so having 2/passives. Or could i use my 5" vk fan turned down to 50%, allowing me to close the passive intakes off.although this would mean my extraction would be on max. As I only have one speed controller until I can get a twin. Thanks in advance.
  19. So this time I'm looking for advice on eliminating the fan hum/buzz from my RVK 4" and 5" fans. I've tried building a leepy box although to be honest it wasn't a very good job but still found the hum to loud for my liking, I'm going to give it another go and try out different fillings.. I've got some acoustic foam that I was using but was hoping it would be more effective than it was.. but like I said it wasn't the best attempt.. and I'm not happy with my ducting either but the acoustic's fibreglass is a f*cking pain to work with although it does eliminate the "whooshing" sounds.. Someone has suggested using a "variac fan speed controller" although the ones I've found seem a bit steep in price and complicated to wire up.. I'd ideally like the fans to be moving enough air yet as near to silent as possible.. I only recieved my fans yesterday so not really looking to go swapping them and looking to not spend too much more on my grow but can't compromise security either obviously. also need to order some 4" ducting for my intake so can only improve my 5" for now but any suggestions for aiding in soundproofing my grow are welcomed! edit: ..attempting to solve it myself but It looks as if I'll be spending 100+ on a decent fan controller, can anyone confirm if these will definitely help? I'm seeing lots of different types but I don't want to go and buy something expensive and not very good.. Greens have "SMS Twin Fan Speed Controller 4.5A" which seem like they might do the job whilst still being plug and play but I've seen "hybrid" versions which look even better but cost a bomb. this does your head in
  20. Just need some advice/opinions on single fan filter and hood set up's, currently I have a 4" filter and and fan (wolfnado) twin speed. So currently have the filter connected to one end of the hood, the other end of the hood connected to the fan the fan is sucking air out! Some air is sucked through the not so air tight hood, so some smells do escape! A fellow grower has suggested that instead of sucking that blowing through the hood might be better? Any opinions on that? I know I should probably run a separate fan for the hood but I'm trying to minimise the amount of equipment etc...
  21. Hello everyone, I'm starting to look into making a new wardrobe and I'm stuck on the fan choice. I really need a much silent solution as possible, I've read that it's better to get a 6" and running it at slower speed then a 4" one, can you confirm? Is it worthy to buy a silencer? any recommendation? Is it worthy to spend extra money for the Tornado MDF Acoustic fan? Any other solution or recommendation? thanks
  22. fan

    Hello, I have some limited space with lighting and I wonder if I can place the fan like this. [/size] If I use ducting to place it on the floor it will be too far away. What do you think? Can it cause problem to the top of the tent ?[/size]
  23. Hi guys, I,'m a newbie, so this is my first post. Your forum is really amazing with lots of useful information from the pros. Im about to set-up my own grow room, and I've ordered 2 SL-400 LED lights. Now I'm trying to set-up the ventilation system, so I decided to go for system air for its performance and durability. So my grow room is a master bedroom with an attached bathroom, and the bathroom has a little window with an extractor fan. I was thinking about taking advantage of the bathroom fan by taking it out and install a wall-mounted system air fan with a carbon filter and extracting the air directly outside without worrying about ducting. However, I'm not able to find the KV 150 XL Circular duct fan or any similar unit anywhere online. Could you please help? Your input is highly appreciated.
  24. So the pixie tents gunna be 60x 60x140, well 60x50x140 when I've shortened it a bit to fit the space I got, and will be using 300 wattx 5 watt diode led, not a 3 bar fire in there. I bin speakin to other micro joes on this site and they say that a 4" make too much noise. Last 1x1m grow I did I used a 4" on half power most the time,but it did have fresh air intake where as this time I will have bedroom air for intake prob using a pc fan to encourage air flow It seems to me folk maybe goin for overkill on this site, that said noise is an issue this time round so it's goin in the attic. My thoughts at the mo are 5" on half power or less gotta be better un running a 4" at full pelt eh, or maybe even a 4" on .75 power it aint like I'm extracting the gladsto dance tent, thorts please folks.
