  1. Hi. I am trying to design my own grow room. Right now the dimensions are going to be either: 50 cm (width) x 75 cm or 90 cm (length). I have ordered the wood and everything but now I'm starting to wonder if 50 cm is big enough? This is my first grow so i don't know what the minimum dimensions should be. The reason why the grow room is only 50 cm (width) is because i live in a small apartment and i want to keep it stealthy. Do you guys think it will make a positive difference, if i made the grow room bigger? (60 cm width instead). I can't make it bigger than 60 cm though Stiggy
  2. Hi guys. I need some help so I have a couple of questions. I’m going to build a small grow room (scrog) 55 cm x 55 cm x 120 cm (height). This is the calculations I did for the fan: 55 cm x 55 cm x 120 cm = 1.80 x 1.80 x 3,93 (feet) x 3-4 = 38,19 - 50,93 CFM = 86 m3/hour I guess my fan needs to have a higher cm/m/hour than that. I have been looking at this fan: I am going to be using a variac speed controller. I think I want to use the fan at 40 % of its max speed, in order to make it more quiet. http://www.onestopgrowshop.co.uk/fans-filters-and-air-control/duct-fans/systemair-rvk-5-inch-125mm-l1-in-line-duct-fan-341m3-hr.html : 323m3/h or 190 cfm. 40 % speed = 129 m3/h or 76 cfm. I have also been looking at the Ruck (can fan) and rhino fan. My first questions is, how powerful should my fan be for this grow room? Is this okay: 129 m3/h or 76 cfm? How much higher can a fans m3/h/CFM rating be than what the grow room needs as a minimum? My grow room is not that big, but I think I would be able to fit that fan inside of the grow room. I am going to put it in a box like this: https://www.icmag.com/ic/showthread.php?t=229614 (of course not as big) and then use oversized insulated ducting. The lights I’m going to use will be something like this: http://timbergrowlights.com/200-watt-cree-cxb3590-4-cob-grow-light-kit/ (DIY by following a guide) What size of carbon filter should I use for this grow room? My grow room is not that big, so I hope I will be able to fit everything in it. Should the carbon filters cfm/m3/hr rating be higher or lower than the fans cfm/m3/hr rating? I hope you are able to understand my English J Stiggy123, Denmark

  6. hi people i have some extra room in my veg cabinet roughly around 40x40 in width and depth, with about 80cm height (50-60cm in grow height) i have some Sweet Seeds Black Cream Autos available, as well as a freebie Auto Seeds Auto pounder with Cheese my plan was to stick 2 in the cab, so i need to make sure that they dont grow too tall. my guess is that pot size will have a great influence on how tall they get, So what size pots do you guys recommend ??? i have 1L, 1.5L and 5L pots available cheers Gmaan
  7. Evening guys, hope you're enjoying your weekend! just a quicky about seed size.. I've had quite a few bag seeds over the years, so have got used to the general size they come, yet I've just received my seeds from Herbie's and they seem to be very small to ones I've had before? I've had a few seedy kind of bits of bud that 'half-formed' seeds have infested the bud and these reminded me of them. I'm just wondering does the fact they are fem'd somehow make them smaller? or are different strains different sizes? - no offence towards Herbie's, and I'm yet to even try to germinate them, just a general question about these magic beans!
