I was in the Aussie seedbank thread, dunno how it attached over here. Gremlins.You in the right thread mate??
That would be a lovely sight.I'd tend to agree. some of my best harvests Outdoors at the tail end of the wet season after500mm of rain in the final 3 weeks.

I hear you all, but somethings not right with my setup. 50% outside humidity and 100% inside tent humidity.
i tried opening all 3 flaps at the bottom of the tent hoping the exhaust fan would pull more fresh air in for exchange. Did not change at all. Then tried closing 2/3 flaps trying for more negative pressure. nothing changed.
Then i stuck a fan blowing into one of the flaps and it dropped it to 85% Still higher than the RH around the tent but better.
I did some calculations with the fan i have, with these specs.
- 31 dB
- 164 cfm (280 m3/h)
- 0.13 amps (30W)
- 205 Pa
and the size of the tent, 2.4ft x 2.4ft x 5ft = 28.8 cubic feet
Then used this formula: (Base CFM x Component factors) x (Grow light heat) = Required CFM
28.8 + 20% ducting + 20% carbon filter + 50% grow light heat. As according to the Ac infinity calculation page.
= 62.208CFM To which, if the factory specs are accurate is more than double the required airflow. So i think the Exhaust fan is strong enough for the tent size, but just doesn't seem to help pulling out humidity.
I wish i had bought a larger tent, even just to use one side of it to grow and the other to house a decent fan. I'm really limited on fan selection for the size of the tent area currently. Money is extremely tight right now. otherwise i'd just go out and buy a larger one.
Also the Fabric pots are always soaking wet on the bottom. they sit on top of small 1" rises to keep them off the bottom of the saucers. I might have to try getting them up higher so there is more airflow under to help reduce the moisture that would most definitely be contributing to more humidity.
If anyone has any suggestions as to fan placements in smaller tents, airflow direction all that stuff would help especially if its been done n a smaller tent.
I think i also will have to work on an intake fan some how, checking it out now its 60% humidity and 83.5%inside the tent so the intake fan blowing in is definitely doing some work.
Cheers for all the input guys.
Doesn't add up being the 50% outside and 85% in tent with extraction. Is there water pooled under the pots? Can you feel the air rushing out from extraction fan?I hear you all, but somethings not right with my setup. 50% outside humidity and 100% inside tent humidity.

is that a computer fan?
I just watched your video, I'd expect to see dribbles running down the walls if your at 100%.
Hows your carbon filter setup, if it's a 30w fan pushing it I don't believe that would be powerful enough
