Cannabis Grow Rooms

Alrighty, someone here will probably think this is a silly question but to be honest with you I'm stumped. Currently my grow-drobe is running a little hot for my liking (26-30 degrees during the day, yeah i know not the end of the world but id like to see it come down a few degrees, so my question is this, I want to add some active intake, currently I have a few vents supplying fresh air but I want to lower the temp beyond what vents can do, so I ask, what is more beneficial, higher rpms or higher cfm, now i know that rpm is the speed of the fan and cfm is how much air it moves, but it just seems odd to me that a fan that when held against your skin feels like its hardly…

My brother just bought a second grow Fridge thing (Monsta Grow) ,, and on the shade there is a box/adapter that says it will run up to 1000 watt HPS Has any one seen anything like this before ? I will try to get some pics of it sent to me .

Hey guys i just put my little seedling 4 weeks old on its 5th node now under a 48W (200W) CFL i am wondering could i grow it under this light here for 3 - 4 weeks then put it back outdoors when October starts cos then its spring. also approximately how much would it cost me to run this globe 18/6 for 3 - 4 weeks?

Hi, I've got a 400w high bay light that I want to convert into a remote ballast, I know roughly all the electrical stuff to do but my plan is to connect the ballast to my current euro reflector that I have. I was wondering if I would be able to use a standard (tube like) bulb? I want to do this as i've heard the round reflector that comes with the unit tends to focus the light rather than spread it out, plus the bulb that is in there is a oval shaped mercury vapour one. I want to put in a 400w mh bulb. I know that the bulb will physically fit but will it work? Here are the details I can get of the ballast: Luminaire: prismpack 3 No: pp93 Use: 400 watt GE/MH Lam…

Can anyone reccomend a reflector for my wardrobe dimensions are 91cm wide 54cm deep. I see the adjusta ones how well do they work?

hey guys i've bought a primair fan controller, with a thermostat and speed control for 2 fans. My problem is that my filter/fan combo is meant for a much larger room. My room has (and can only have) one vent for air in. so when the temp gets above what i've set on the dial and my exhaust fan comes on full power i can hear the motor strain as the room is under negative pressure. Before i bought the primair controller i just had my fan on a fan speed controller i borrowed off an old ceiling fan. Can i some how wire that in to slow down the fan when it comes on full power? or, as i'm not using the 2nd fan dial, can i wire that up to control the speed of fan1 when the ther…

Hi there fellow members, just picked up a GE Lucalox HPS 400w horticultural globe for nix, any one used one? Can't find much information about them on the net other than hydro suppliers group them with the Son-T's and the GE Lucagrow.

What level of humidity is ideal for grow rooms?

Anyone out there used leds for growing before and what sort of results have you had. They seem to come in 90w, 300w, 600w and claim good results with minimum power consumption. I know they dont have the aus safety tick thats why the shops arent selling them??????????????

Hi W.G., I have a few seeds of Romberry, a Romulan and Blueberry cross, Original Blueberry, Green Crack and two others but I don't know what they are but only know that they will be good stuff. The two that I don't know were dropped off at my house in the states from another grower I know who always had some exotic shit but I wasn't there at the time to mark they're names on the bags and I forgot what the names were. It was when we were right in the middle of our move to here to this country so everything was a bit crazy at the time. I just tried to sprout 12. Nine sprouted and after transplanting six of the nine died. So I am now sprouting more. I had a problem …

Are led lights good? How many would i need per plant? How much do they cost? What type of LED would be use for marijuana colours red and blue? Any info links ect will be appreciated...

Hi Guys, Because of high temperatures here I have been forced to run my lights as much as I can during the night to keep the temperature down, last night i found a BIG problem.... due to it being a rental property and I cant vent though the roof, I actually vent my fan out the window, which is covered by a thin cotton curtain to allow air to penetrate the curtain, the window and curtain in then covered in builders plastic with only a small round hole in the builders plastic to allow the air to be vented through the curtain and out the window. ...unfortunately at night the vent shows up as a glowing yellow hole through the curtain....looks pretty suspicous, fortunately…
