hi all my grow room is 3m x 1.6 and 2.3high I am running at the moment a 1000w epapillon running 18hrs and have a 8inch canfan running all day. with everything running it only gets 22c in there so I bought a growlush fan speed controller slow the fan down to make it hotter but the motor makes an awful humming noise even when backed off 10%. Just would like to know if you can put the fan on a timer say 15mins on 15mins off for example or dose that cause problems. and can you get any other controller to work without it making that humming noise Thanks all

Hi guys, I currently veg my clones under a 250w MH to about a foot high before sticking them outside to flower in winter. I have a new batch of clones ready to go but have just been surprised with a fishing trip to NZ by my girlfriend in a months time. My question is to veg these clones faster so I can put them outside before I leave would it be better if I used a stronger light say a 600W? Or should I just try and increase the nute levels to the maximum they can handle. Any advice would be appreciated

Hi guys, I'm a noob and needed advise on the correct cfl to use on seedlings.I already have 6400 and 2700 cfl's ready to go but read somewhere the other day not to start seedlings on the 6400 because it to much.They went on to say use a 23 watt cfl to begin with.I'm confused, but if this is correct then when should i change to the 6400 or should i just start with the 6400 cfl.All advise welcome, and thanks Widowman

Going to get myself a 1.2 x 1.2 x 2 meter tent and wondering what fans you guys would recommend.. Im also wondering what you guys find to be the quiter running fans.. This will be my only intake as well... CF > fan > outside I would like something that I dont have to run at full speed to get the negative pressue.. I have heard someone else on here mention its good to get a bigger fan and dial it back to assist with noise.. so any brands that have a controller included would be good.... Thanks

Hey all. This is more of a query and to see if there would be interest before I start a classified ad. So, my work place is currently replacing all it highbays lights (400w MH) with LED versions. There should be 22 units up for grabs. Electronic ballast, E38 light fitting, 400w MH lamp and big dome shade. Also I am unable to say how old they are/hours used, sorry There is a thread on here somewhere that shows how to convert them to separate ballast and fitting but I'm unable to find it, although its a fairly easy process! My boss haven't said a price yet but If anyone is interested, let me know and ill find out exactly what sort of price they are looking at. It wont…

I am in need off some seasoned advice please. I just bought an entire new set-up and this is what I have. 5'X5'X8' Tent, 1000W ballast and bulb, CO2 genny, 8" fans for lighting and ventilation. I have been using LED's in a much smaller tent and would like a little help with setup for instance: What is the max (give or take a few) temp inside the tent when using 1000W with CO2 level of 1500ppm? I am using an oscillating fan and 2 static fans for air movement. I turn my vent system on every 3 hrs. to cycle the air and provide fresh CO2. After my 12/12 I use the vent system until it's time to start over the next day. Using Advanced Nutes full pH perfect line in …

Hi Ive been using these domed 600w gavitas for the past 12 months after a friend gave them to me. I think they are awesome and dont require the usual reflector setup. But i cant find a shop that does them anymore. ( apparently they have been replaced )?? Anyone use them? Know where to get them from? Thanks

Hi, Recently I have been noticing that my light isn't turning on sometimes. I need to unplug, then replug it in to fire it up. Light is a 400w son-t agro and ballast is a solistek 400/600 digital. Timer is a manual type with the dial on the front, not the cheapest model they had. I don't think its a timer issue as when it happens, the ballast light is on which means power is going through. I believe that narrows it down to the ballast or the globe. The globe has seen 20+ weeks of growing, is that old? and do old globes sometimes have probs firing up? I believe that my ballast is meant to keep attempting to fire the lamp unless there is something wrong. Anyo…

Hi, Can anyone tell me if this is a reasonable ballast? I got it 2nd hand but the seller couldn't tell me anything about it. It came with a 600w HPS and a 400w MH globe, both work in it. I tried googling but couldn't find anything about this brand, given that it says Australian made Im guessing it should be OK but Im wondering if its safe to run the 400w MH (or any MH for that matter). Thanks

Hi guys first time grower here and have a few questions regarding the build of a grow tent. Im thinking of using a 1.2m x 1.2m x 1.8m tent but im unsure of what kind of lightning / heating / cooling setup i can use. Ive done a quick MS paint in how i think it needs to be done, Does it look correct? Do i need another fan in there gently blowing over the top of the plants as well just to imulate a breaze or something ?How bad would the smell actually get? this is just going into my shed and i was hoping to vent out of the tent and out the back of the shed, Will a carbon filter get rid of the smell? Some companies claim ZERO ODOR but im not sure if thats real? for the fans c…
