kal17117 Posted May 5, 2002 Share Posted May 5, 2002 my grow room is about 4 1/2 ft high , 2 1/2 ft wide and 2 1/2 ft deep. my loft is directly above. i'am planning on 400watt grow light. now if i cut a biggish hole into the loft and have a oscillating fan blowing the hot air upwards would the hole in the ceiling act as a kind of chimmney flu drawing the hot air through it. if i do need an extractor can it be wired up to a normal plug. any thoughts would helpfull. peace....kal.

Delta Bravo Posted May 5, 2002 Share Posted May 5, 2002 Hi matey, Sounds just like the airing cupboard I used for my first grow. I had my 400w in there with an ossilating fan and I ended up cutting the hole roof of the cupboard off. I strongly recommend an extractor. Any DIY shop will sell them and yes, you can wire them to a normal plug. Good luck mate Link to comment Share on other sites More sharing options...
chip Posted May 7, 2002 Share Posted May 7, 2002 Hi Kal Yes, is the simplest answer. A 400w can get quite hot so a couple of fans, one blowing in and one extracing will keep your room cool and provide the plants with more than enough CO2.
