So, my new exhaust fan arrived and with a capacity to exhaust 150 cubic metres of air per hour - 5297.2 cubic feet (my tent has a capacity of 2.88 cubic metres - 112 cubic feet) my humidity problems have been sorted. Well, that was the plan, but life didn't seem to like that plan. I hooked the new fan up to the carbon filter and watched both temps and RH rise until Rh was back in the mid 70s (less than 50% outside of the tent), so, I figured the carbon filter would be reducing performance by about 20% so I unhooked it to run exhaust fan only, but it made little difference.
I have only been running with a passive 4 inch air inlet, so figured I'd add another another one plus use the old exhaust fan for intake as well. The upshot of all these modifications is a big fat zilch, nada. None of it seems to have made much difference at all. No, that's not true; I'm being harsh. Humidity levels were exceeding 87% at times and it is currently sitting at 75%, so it has made some difference.
On the plus side, the carbon filter is working great and I thought I would show how I made it.
Here it is installed in situ.
I used a large tin and drilled hundreds of 8 mm holes and did the same to a smaller one. I wrapped both the tins in stockings and placed the smaller tin inside the larger one and filled the void with activated carbon. Both of the tins had plastic lids and I cut a hole in the centre of both fractionally smaller than a pringles tube. Cut the end off the pringles tube and inserted it into the lid of the smaller tin and sat it about an inch below the level of the lid. I then inserted the tube into the centre of the larger tin's lid and closed it up. I then wrapped some micromesh fabric around the outer surface of the larger tin and secured it with an elastic band at both ends. I then rolled about an inch of the stocking over at each end to further secure it.
Once that was done I simply connected that up to the fan using ducting as can be seen in the above picture.

Thanks guys and welcome to my journal Wiley. I hope you can stick around to see some nice buds when they're done.
You would think with that much exchange it would drop RH to just above outside RH.

That's what I was expecting. There must be something I'm missing, but, for the life of me, I am all out of ideas.
Ill be dealing with high temps in the near future

I've only been getting tops of just over 27 C (80 F), so they've been nothing to worry about. What sort of temps are you looking at PW?
Mid 80's in the afternoons

That's not so bad then. You see some of our Australian growers were dealing with outside temps in excess of 100!

How'd you go with doubling your intake? My humidity inside my tent is about that of outside using a 6 inch passive intake a cheap steel 6 inch exhaust inline with a carbon filter I'm still seeing my tent being sucked inwards.

I'd be curious how your humidity is when your tent is full of girls in flower all breathing out hot, moist air from their leaves and frilly knickers. My humidity is currently on 75% and that's with the two 4 inch passive intakes and the computer fan as an active intake.
I was thinking about a 6 inch exhaust fan, but after reading up on fan sizes in which it was recommended to change your air volume every 3 minutes and allow 20% for a filter, I figured one that claimed 150 cubic metres per hour would be more than enough for a 1.2 x 1.2 x 2 m tent. I can only imagine the manufacturer exaggerated their claims.

I just rotated the auto and liked the view so I figured I'd share.

I was still getting readings of 77% rh so, as a temporary measure, I reversed the inflow fan to exhaust, but that kind of defeats the object of the carbon filter. This managed to bring the rh down to 65%, but that is still a lot higher than I want.
Still mulling over what to do. I'm consider adding a larger fan in series that's rated at 220 m3 per hour. If that doesn't work ...

RH is beast where i am at, hope you get a handle on yours.

Day 80 Multi-Coloured Pictorial Update
Auto Day 25 of Flower
The Rest Day 22 of Flower
The WWXBBs and the Quick One Auto are starting to get nice and frosty. Brushing against the WWXBBs releases a delicious sweet smell that takes me back to decades ago when I grew outdoors back in Australia. In those days, you never knew what weed you were buying or even what strains you were growing. Sensi seeds and the Hash Museum were already there in Amsterdam, but there was nothing like the volume of seed banks and breeders that you have today and ordering seeds via mail was only a dream in Australia. Obviously, these WWXBBs share some of the same genetics that I remember so fondly.
This last pic is the Quick One with a magnifying glass in front of the camera lens 'cos the shitty camera doesn't have a zoom function (or, I've yet to figure out how to use it
)

Now, for anyone who's followed this grow, you will notice that there is no mention above of the Mystery Girl reveg. This is quite deliberate and something I thought worthy of a separate post. Not one of the 3 clones are in the same league as the other two strains. Heck, they're not even in the same sport. The buds are spindly with just the merest hint of trichomes and a very faint smell. I have, therefore, reluctantly come to the conclusion that she is just a poor quality strain not worthy of continuation of her lineage.
We are expecting sub zero temperatures this week so I've brought all the clones insides from the greenhouse except for the two Mystery Girl clones. They've been plopped into the compost heap to do as they will, though I can't leave them to grow if they miraculously survive the upcoming frosts. I just can't bringing myself to actually kill them by my own hands.

I remember our outdoor grows years ago, in my area everyones "strains" all looked and tasted the same. Years of inbreeding with very little outcrossing. Some of it was unbelievably potent though.

So I've been playing around with the camera and found a HD setting and also have been playing around with the colour balance.
I need a decent macro for my phone.

If the WWXBBs are like this after only 3 weeks, wtf are they going to be like in 6 weeks time?
Oh, Old man, I think you may have missed the above post about the mystery girl girl clones
