Hi guys, So my problem is in my 80cm x 80cm x 180xm tent my temperature will not go below 90F. I am using a small extractor fan attached to a small carbon filter the fan is 105m3/h (61cfm), they say that a carbon filter + some bending in the duct reduces the airflow by like 20% so I guess its...

Sorry I thought you ment inside the tent when you said "room". My room temperature outside the tent is 70F

Ambient air temp is 90F and this is the kit i am using for extraction: http://www.ebay.co.uk/itm/201019082703?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Thanks for the input just reassuring me that i need to get a better exhaust fan i guess. Any idea if an intake fan on the duct would reduce the temps by much?

Ive seen these before they seem really effective, the only problem is i would have to plug my fan in inside of my actual tent which would be abit of a pain. Would you have any idea of how much 50 extra cfms on a new exhaust fan would reduce the degrees of my 80cm x 80cm x 180cm room?

Nope theres nothing in there atm. Im just doing alot of testing right now to make sure i can sustain plants and its not a huge fail and waste of time and money. Im going to be doing autoflower to start so lights will be 18/6 from start to finish (lights on from 6am-12pm, 12pm-6am off) i was...

That sucks as ive just bought this 1 and put it inside an insulated box to keep the noise down lol. My carbon filter can only handle 117cfm (200m3/h) so would it be better to get a fan that exhausts 185m3/h and have it on full blast 24/7 or a fan that exhausts more air and turn it down? Noise...

Temps from the passive duct (located on windowsill next to a window) are around 60-70 in day and 50-60 at night. I can close/open this window to change the temperature of where it is intaking from (about 2m of duct from window down to bottom corner of the tent)

So would you guys say that the only way to bring these temps down to something viable would be to upgrade my exhaust fan?

yeah i considered that but my tent is kinda small and them exhale bags look kind of heavy, i see this which looks cheaper and alot lighter so i can hang it up without problems what do you think...

Ok ill add some of that then, i have my ph up and down bottles ready. So would you say its viable for me to do a grow or is it just not worth the time and effort with those temps?

ive heard about silica before, how would i use it? I am planning to do one feed with nutes and one without and carry on like that, would i add it to my nute feed or just my plain ph'd water feed?

Nope not a chance

Ok so canopy maxed out at about 91.5 Ambiet was around 89.5 and root was 89 :(

appreciate you taking your time to help me

measuring them right now

Have nothing to upload a pic with atm im afraid

Hey guys, Quick question: I cant get my room temps below 32 celsius (90 fahrenheit) with the light on (80cm x 80cm x 180cm) tent, using 600w(275 true watt) LED with no plants inside yet. I have passive intake and 4" out take. Humidity levels are fine. Done my own research and seems like...
