Cannabis Grow Rooms

Ok so I'm using a grow lab tent and I bought a new led diamond series xml 350 light it works great plants seem to stretch alittle but nothing horrible . The problem im having is the temps in the grow room are alittle cold running about 70-71 degrees f when I want about 75 maybe this is the cause of the stretching but I was wondering how I could raise the tempeture I have thrown blankets over the tops and sides. The tent is on carpet and I put 2 fans at the top of the tent to blow the hot air down but the temps are still low how could I raise the temp to optimal range. I have read humidifiers but I don't really wanna drentch the room either any suggestions ?

Hi Guys, After some advice. Looking to build a room going to use melamine 2.2m high, 1.8m wide, 1.2 meters deeps. Thinking of building my own 315w ceramic metal halides using the $200 Philips ballasts globe and and adapter in the gavita triplestar reflectors. looking at having 2 of those and 1 600w hps in the centre. What would be the recommended intake and extraction fan for that room looking at doing two plants. Advice would be appreciated.

im thinking if i can come up with the $600 im going to think about adding Co2 for my flowering period but im having difficulties using the online Co2 calculators, does anyone know how to calculate how much Co2 is needed in litres? im on this site https://hydrofarm.com/resources/co2calc.php i punch in 4.5x4.5x8 foot as a rough estimate of my new tent (1.4x1.4x2m) desired Co2 levels 1500PPM its saying i will need 0.2 cubic foot per hour that equils 5.66 litres per hour now looking at Co2 cylinders there is one on ebay 9kg holds 6 litres if im correct that cylinder will last 1 hour? how does this work? the whole imperial to metric has me confused, should i just thi…

Hi All, I'm after a bit of advice. I'm in the process of planning out my grow room/space. I have an under the stairs spot that's approximately 1400x800x1000. I've got myself a 400w HPS. In regards to ventilation, I am in the process of putting in sub-floor ventilation into my place to keep under the house dry and intend on splitting off one inlet to my grow room. I'm concerned about a drop in pressure as this ventilation will be running the length of the house, not to mention having 3 inlets. The fan will be a centrifugal 200mm fan. The inlet will be dropped down to 2 x 150mm inlets and then one will be split off to my grow room. So there will be three inlets in tot…

Looking for a fan for the cooltubes and came across the Panasonic Whisper Quiet Line Series...USA only. They are 120volt so will need a transformer, but are meant to be super quiet. Anybody tried one here in Oz? http://www.panasonic.com/business/building-products/ventilation-systems/products/whisper-line.asp

Hi all, we're setting up some more LED vs. HPS experiments to identify better growth patterns with different LED spectrums blends and day/night periods. As such we're looking for some gear: Grow tents 1x1x1m roughly 250W HPS & MH kit 600W HPS & MH kit Who's got the best HPS systems these days, I've been looking at hortilux and growlush, but obviously there are hundreds of brands. What are people using most these days? I know the philips ones are great, but they're damn expensive. Any recommendation for some super cheap tents?

So I have myself a good tent for 'tomatoes' that's about 2 metre tall by 1 metre wide. I've been looking at lights that a) arent those 225 things from China that reak of 'great build quality' reasonably priced I've come across some lights, however need a bit of advice on the wattage/price and the type of light, To my general understanding, more wattage= more coverage/ slightly better yield However I must take into account the size and coverage of the light and costing. http://www.ebay.com.au/itm/2013-240W-LED-Grow-Light-10-Spectrums-IR-Indoor-Hydroponic-System-Plant-Ufo-Hot-/261216390610?pt=AU_Seed_Starting_Hydroponics&hash=item3cd1b5cdd2 is a 240w full spec…

Long time smoker 1st time grower ( 2 successfull yields ) like the write ups of the Phillips D-papillon 315w. There seem to be variations on what to buy. ie: open reflector, some have a protective glass for Uv from bulbs cracking. Anyway anyone use these ? if so please give me some advise, Iam both baked & confused.

Gday all I think I already know my answer. But here goes my tent is 1.4 by 1.4 by 2.4 I have 1 4 inch fan pulling air out from top another 6 inch fan attached to my vented hood that I have some ducting connected to suck hot air from under the light and beside tops of plant. My intake is 4 inches down low. My temps get up to 31 with door closed but if I open it half way I get temps down to 27.5 degrees. So I'm thinking I need a bigger intake would this be correct

has anyone here imported anything indoor growing related from the UK? looking at one of these particularly http://www.ebay.com.au/itm/150mm-6-370-m3-hr-Acoustic-Low-Noise-Silent-Inline-Box-Extractor-Fan-Hydroponic-/331406587163?pt=UK_Baby_Baby_Feeding_Bottle_Warmers_Coolers_LE&hash=item4d295f351b 25db sound levels and half the price of a local silent fan bought over here im keen to order and im coming up to a harvest so looking to redesign my veg and flower tent, possibly run one fan and vent both tents with filters at the moment running one filter in the flower tent

hey guys im a bit of a newb when it comes to "technology" i have only ever ran old technology magnetic ballast so i have a question, in my 1x1m tent i feel i need more light so i have the master plan of running a bigger light on my next run i was thinking of going with a magnetic 600w light but than i thought i should ask before hand, will i be better off going with a 400w digital ballast on super lumens, 600w magnetic light or even a 1000w digital nanolux light dimmed to 50% which will be 500watts of course if i was to go the 1000w HPS dimmed at 50% does it put off much more heat than the 400w HPS? i have never owned a digital dimmable ballast before and i have never…
