Hi guys i need some advice on how to make my fan quieter. I have a 150mm Axial Spectrum fan, surrounded by 200mm x 3m of Insulated Ducting, The fan can still be heard from the road. What is the next step to reduce the noise? I would like to get out of this as cheaply as possible, the options i have thought of are; Wrapping 250mm insulated ducting around the 200 150mm Odor Sok (would it be able to pull air through this?) Some sort of silencer box (made of Styrofoam) or other material to be advised? An extra x m of ducting Fan controller Thanks guys, your help would be appreciated.

Hey everyone, hope everything is all well. Just a quick question about my cab, I have a grow area that is 2.5 foot wide, 3 foot tall and 5 foot long. Its in my room so i have to keep it quiet which i have achieved pretty well, it has a 250 ball-baring inlet fan which keeps it cool, and another 6 inch cpu fan that sucks the air out of the cab, through the cool tube and blows the air out of the cab as my outlet fan and keeps the cool tube nice and cool. Was wondering if another 6 inch fan would have enough force to suck the air out and through a small carbon filter to take away the smell or if i would be better of mounting a ozone generator to kill the smell inside the…

Maximum Yield Article. LEDs: Lighting for Hyperspace Crops or Just Hype? "There has been a lot of buzz surrounding LEDs (Light Emitting Diode) amongst indoor gardeners in recent days. The feedback varies; some people are wowed by this new technology while others are disappointed. So what are some of the reasons for the polar opposite views when it comes to LED lighting for crops? In this article we will examine some aspects of LED lighting, and perhaps shed a few photons on just what LEDs have in store for the future of indoor gardening. This certainly won’t be this writer’s last article on the subject either, as this emerging technology continues to evolve. As …

Hello everyone. I am doing a closet grow SOG style, and the two separate cabs are about 4 foot long, 2 foot deep and 4 foot high. I have a 400 watt cool tube hooked up and i want to keep it quiet so i was wondering instead of running fans, can i just hook up a aircon unit, and run a tube to cool the light down, and another down to the cab to keep it at perfect temperature. I will open the door 2 times a day to let c02 in and all that. But was just wondering if thats do able instead of running fans to keep the tube cool and cab cool. Thanks heaps

Hey folks sorry if what I'm asking is common knowledge but I'm only on my second grow indoors (ever) Should my light (400w hps) be running vertical or horizontal from the top in my grow cupboard? The light globe is currently pointing down at the plants (vertical) I guess it will be a SOG as there are six in a smallish area

Hey guys. I'm in desperate need for some help. After a week of working fine, I plugged my 400w (and ballast) in to start a cycle and I got this almight crackling sound through my cords. I know the sound was electricity, and when I unplugged, the metal tines on both plug attachments were blackened. Why? What? Everything was going so well. I checked the wall outlet with a normal lamp, and it seems to be fine. The extension cord I was using has been fried and doesnt work anymore. Everything else in the house is working fine. I'm too scared I'm going to kill myself so I haven't plugged the 400w back in and my babies (4 days old) and on the window sill. I'm afraid i…

Im looking at 4 Phillips Ecotone Cool Daylight, High Lumen twister with built in fans 65w CFL's (degeres kelvin 2700-6500, colour index reading 65, light output 5500). Would this be enough for a 6-12 seeds throughout veg. I plan to grow 4-6 in my grow tent. I have a 600w growlush HPS but am thinking ill use that to flower and use the CFL's to veg (less power consumption). Ive got a recurculating hydro setup ready to go. I read so many confliction ideas, can i have some of your opinions???
