Cannabis Grow Rooms

So i've been reading around the forums on lighting, and have heard people talking about having different lights for veg and for flowering. Is it vital to have different lights for the different stages? or can one get away with the same lights?

So heres the deal, im in the process of constructing a grow box for 1 possibly two plants and am struggling with finding the right lighting. Im going organic as opposed to hydro, and first of all cant decide between HID and cfls. I've heard that cfls are cheaper and not as hot as the HID which is good for me, but do they achieve as good results? Also what wattage would i need for either HID or cfls? i've heard from 70 watts to 150 ea. thats a big difference. its confusing. Any advice would be great. TGD

Sup, first time poster, short time lurker. so I have been doing some research on low-heat LED lighting systems and it seems to me that you can make a very cheap system in about 15 min, using blue and red led's and some Christmas lights. It seems that, blue LED lights by their nature of being blue, emit about 460nm wavelength (perfectly in the chlorophyll absorption range in the vegetative state 400 - 500 nm) and red LEDs by their nature of being red emit 660nm wavelengths (perfectly in the chlorophyll absorption range in budding state 600-700nm) dick smith/jaycar and others sell these for about .20 - 50c each. It seems that I can pin a blue LED filled Christma…

Hello Everyone, I have just purchased a 250W MH for keeping my mothers and vegging clones prior to putting them outside, just curious to see if anyone can give me an idea of how big (or small) a grow tent I will be able to use, I was hopping to have two mothers in the grow tent with at least four clones vegging (to about 30cm tall) continuously. what do you guys think?...is this feasible??

Hello everyone, I have decided to lash out and buy a decent light to keep my mothers under instead of just using fluros, I would prefer to just get a 250w MH or HPS ( prefer MH) but I cant seem to find any 250W for sale anywhere?? Could someone help with stores, would prefer not to buy a 400w if I dont have too

Am looking at setting up my first indoor grow. Purchased 4 130W CFL lights, 2 for growing (6400K and 14000K-blueish) 2 for flowering (2700K and 25000K-its purpleish). Using a converted outdoor dunny with about 90cm long, 60cm wide and as high as i need (2m, although won't go that high). Can double that space but starting small. From the info i can find on-line the 6400k and 2700k are right wondering about the others. How many plants (was thinking 2 or 3). Each CFL has approx 10-11000 lumens (so 20-24 at a time). Any advice appreciated.

Hi, everybody ive just setup my first and new grow tent (1.2x1.2x2) with a 1000w in a ducted cool tube and 3 big squirrel fans (one for intake and outake and one blowing through cooltube). I left everything on for nearly 2 hours for a test and the temps went from 32c to hovering between 36c-38c Unfortunately people would see if i was to stick the ducts out windows and i cant put it through the roof because im renting. I know the obvious solution is to buy a portable Air conditioner but im broke so for now the hot air will just have to circulate around the room. So my question is will my *cough* tomatoes grow good in these temps and should i germ my seeds (from a bree…

Looking for opinions on using a 400w hps for vegging mothers Thanks FC Edit: I mean as opposed to using MH, any opinions against it?

Hello all, I've build a grow cabinet in my bedroom with an old wardrobe i got for free. I'm exceedingly pleased with what i've constructed so far, but damn is the fan noisy! I've got a 240v fan from a local hydro shop, and it's no drama when people are moving around and the TV is on in the house, but when i go to sleep it's pretty loud. I was wondering if there is anything you can get off the shelf to reduce the current to the fan to slow it down a bit. Heat isn't an issue at the moment but i'd like to keep the fresh air circulating. Thoughts?
