Hey fellow tokers i just ordered a Secret jardin dr60 so basicaly 60x60x150 and am stuck with what fan to get. I can get a 130cfm 3 inch inline fan but not sure what itll do after sucking through a small diy filter. Thats basically the closest size i can find in a reachable price range. Due to the tent purchase funds are mostly gone for now, i havebalready got a grow going at the moment which has no way of venting so only got oscillating fans inside so hence the purchase for tent and smells getting bad. I live in new zealand so the cheapest fan i can find is this 130cfm bildge fan for venting boat engine rooms. Its 12v too. So i guess my question is will it be wnough cfm through a small filter to work for my tent. I measure in cm and also as a setup i will be growing 4 small to medium sized and well trained girls in this tent. I know youll probly come and say its too small for that many but ive have 4 plants in an even smaller space before with good results (for a micro grow that is)


Im using 350watts of true cfl wattage

To get the cfm sorta right for the extractor times the lengthXwidthXheight by 20 and add 20% for the carbon filter, if the tube is really long or in a hot place add more. Ventilation is so over looked and if you can add a intake that has a 1/4 strength of the extractor.
With 350cfl you'll be looking at a good bit of weed on the go. But I would recommend getting a 250watt normal grow light Mh to start and hps to flower them. Happy growing

What do you guys think of this idea. I can either grab a 4 - 5 inch inline from ebay and have to wait a month or so or i could spend the same amount minus abit of shipping and time and just get 2 of the small 3 inch ones that i posted a pic of and either run them with a small filter each or just y them into a slightly bigger/longer single filter and just have them on a fan speed timer in the unlikely case of over cooling the tent
