Cannabis Grow Rooms

Just a quicky here. Can you tell me if or how to use cool tubes on a light rail?

Hey all, found some interesting info for anyone setting up multiple ducts in their room. Chef Read On: Flow of Air Now, the challenge is to get the proper amount of air into each room at the same time. This is where things begin to get complicated. Here is the problem. The furnace blower fan only creates a certain amount of energy at any given instant. This energy is constant. If one room gets too much air (energy), there won't be enough for the remaining rooms. Remember, different amounts of air (energy) are going to each room. To achieve the goal of getting the proper amount of air (energy) into each room at the same time is to have equalized static pre…

hey all, I have a 6x6x6 room with two 600w cooltubes, and am wondering if one 150mm centrifugal fan will be adequate to vent the room through a cf AND the cooltubes. My room has a passive intake. i am a bit stumped on setting it up. Should I go : CF, fan, split to cooltubes, exhaust? Or: Passive intakes for cooltubes, 3 way splitter(one for the Cf), fan, exhaust? I have heard it is better for the fan to blow air through cooltubes, rather than suck hot air through the fan. Any suggestions will be greatly appreciated! Chef

Hi people, Got issue with room hovering around 30-32 degrees under lights. I have two pedestal fans, a 200mm inline air intake from outdoors, a small portable aircon (which does F'kall) and carbon filter drawing air out. To me it seems the carbon filter isnt drawing out the air quick enough. Would it be worth getting a 300mm inline fan just to draw that extra hot air out of the room Summer hasn't even kicked in yet. Also my room is set up properly and insulated. Your thoughts please................

hey guys im almost finished seting up my grow room all i need is 3 fans cooltube and ph/ec testers going to get that tommorow. i need a 250mm fan for the CF a 200mm for intake and a 200mm for cooltube i really want them to be whisper quiet which brand should i go for also did a room calculation and it says for optimum i need to move 93.2 Cubic Feet per Minute but i want to go for the max which is 110.2 Cubic Feet per Minute i looked at alot of online hydro shops but none of them tell u that info. also wanted to know how many watts are the fans as i dont want to exceed 1000w for my grow op couse then im better off bying from dealers.

Hi all, I'm having a lot of trouble figuring out the best choice of fan for my new tent. Ive been reading so much my brain is starting to overload and I still cant make up my mind so was hoping one of you nice people could double check my calculations please (mostly worked out with the Cannaversity calc.) Tent - 1.5mtr x 1.5mtr x 2.0mtr (5ft x 5ft x 6.75ft) = apx 25.0 sq feet light 600w CFM - 139 Light 1000w CFM - 153.5 (Will be running a 600w HPS for the hotter weather but do want to upgrade to a 1000w HPS later on.) So going on the 1000w specs the room requires 155CFM, x2 that for pressure resistance via carbon filter = 310CFM, x 1/3 for temps = 360CFM x…

This is my first indoor grow, I have a 4 pot dwc in a 36m2 room. I have yet to purchase lights, but am thinking of running 2 600W HPS+MH digi ballast cooltubes for about $380 ea. Has anyone used these, and what did you think? Id really like some good opinions and advice before making my biggest purchase. Thanx, Chef

I recently bought a new carbon filter, after some comments from neighbours... I ordered a mountain air brand, but the one they sent was indoor elements Are these 2 seperate brands or does indoor elements make mountain air filters?? basically I feel they have sent me a cheaper, crappier brand thanks

Hi guys, hoping for some advice on my indoor grow pls. I have just upgraded my inline fan to a centrifugal fan and carbon filter but am really struggling to fit both together in the space I have available. My questions are - does the fan need to go directly onto the filter or can I run ducting from my filter (in the grow room) to the fan (outside the grow room - this distance would be no greater than about 1.5 - 2 meters) without loosing efficiency of both the fan and/or the filter. - can a centrifugal fan be baffled in the same way as an inline fan ? i.e. I baffled my inline fan by having it inside a 200 litre brewers barrel and using pillows/blankets etc as a …

Running a couple 3k 600w MH sunpulse globes... Who else is runnin them? What are your thoughts on them? Anyone had any problems with these globes? How do you think plants flower under tkhese globes compared to HPS? An does anyone know how many lumens these bulbs put off? Cheers, Burnz.
