Not sure about the posted dimensions...is that a 1m x 1m x2m? All fans have a cfm (cubic feet per minute) rating. Sort out you cubic feet and match the fan to that. Seems like I remember hearing that you want to replace all the air every 4 mins, but I may be wrong on that number. Anyhow, your space is relativly small so a huge in-line isn't really necesary.

hi there mate,yeah my dimensions are all by meter,i just bought an extractor fan 4",the only reason for big light as given to me and on a budget!!!!,also added an outlet extenal flap wall vent(130 mm),not quite up to date with the how to calculate your cubic meter etc....(bit dense im afraid as i am new to this ha ha!!!!!)

apparantly the extract rate is 20l/s (72 m3/h. also has a humidity sensor?????????would this cause a problem.

thanks for your input,this site is the best for great info,any advise is being all taken on board

kindest regards

The fan is more than enough to circulate out the air in your space. I am a little concerned about the heat generation inside that small of a space, but that can be easily remedied by leaving some small gaps in your tent and running a small fan, which you should have to help strengthen the stalks anyway. Sometimes the only way to know if there are going to be problems, especially heat problems, is to just jump in and do it. As far as the humidity switch goes, if it gives you any trouble, disable the little bugger!
