Drying and curing in a tent with an exhaust fan

[Shape Shifter]

If I can maintain 65-68F and 50%-60% humidity,

would a 6 inch exhaust fan and filter continuously drawing air through the tent cause drying too quickly from the constant air flow? What about bulk curing on screens or flat sheets?

Not a expert but it sounds like you have good air flow. And if your worried bout it drying too fast I would check them every 6 hours. And for screens that’s what I have plan doing. Laying them out on my net with a screen over once I cut them. But I would for sure put them in dark jars to cure some ppl use glass. But dark is better for the budz

Thanks. @9BestBudz0

Have you dried in a tent with the exhaust fan always on? Checking every 6 hours on something that should take at least a week seems like a lot of checking.

I normally dry in a open room with a regular fan moving air around. First time trying it in the tent like this.

I love watching my babies but I watched and I learn from many ppl so I just pass it down. But with good air flow and as long as ur temp is good ur don’t have to check. But if they are close 6 hours are good. - also I help to comment to getting ppl going. Lol

Is this one of those questions that have been asked a million times already? Maybe I should use the Google.

Easiest way is hop on another stream please that you see that’s going on and ask about it

I got this!

I dry in my tent. It I turn the exhaust fan off. And I use a circulation fan that way they don’t dry as fast.

That's a cool story. @Skoal

But have you dried in the tent with the exhaust fan on 24/7 ? The whole point of me drying in the tent is to use the stank filter, Yo.

Fan on 24/7 will dry too fast.
I have my 6" exhaust fan on a humidistat controller which keeps humidity in the desired range for a slow dry.

I've left the fan on 24/7 and got hay smell, basically ruined that crop.

Now we are getting somewhere. If the humidity in my room and tent is a steady 60% and I want to dry at 55%, wouldn't the fan run 24/7 anyway because it never gets to 55%? I don't have a humidity controller yet.

But I do have a room dehumidifier if needed.

I have my exhaust connected to my temp controller, so my exhaust isn’t on the whole time, only when the temp is out of range from where I set it.

So if the temp remains less than or equal to the desired temp, the fan is always off?

I keep humidity higher for the first few days at 65% by adding humidity w a humidifier on a timer, then slowly bring it down to 60 as it gets dryer.
My exhaust fan is only for the emergency of humidity getting too high and to exchange air a few times but not lower humidity to the point where drying accelerates.

We all dry/cure differently.

Considering the fact that it’s summertime, I don’t have issues with the temp rising, it always will. So I have the controller set to kick in my exhaust anytime the temp gets above 65. As far as my humidity, I have my humidifier set to 55-60%, if the rh goes above 60, it shuts off, if it drops below 55, it turns on. And I have my humidifier outside my tent directly next to the open flap to avoid moisture from getting on the buds.

Surely, there has to be an optimal CFM for continuous drying and curing airflow. The lowest flow I can get with my current fan is about 150 cfm. Might have to pulse it on and off every couple hours with a timer. I think the stank will creep out if I do that.

Thats the problem with tent drying, fans make disproportional airflow to just hang drying in an open room.

Either run your fan to a speed that recreates the room drying, which would be slow and much less airflow than growing the stuff.

Or experiment with shorter pulses. Either way it seems like it will take perfecting and few seem to provide much in the way of accuracy or data to follow m/3-hour etc.

Humidity dosent stop drying and rarely needs changing, if its a humid climate the final dried bud will have a percent or so more moisture than a drier clinate - suggest you dry to your particular climate and ignore humidity, at the moment you just need to focus on air flow and temps. Bud is not shit because of humidity, its nit realky a big factor.

My temp and humidity are stable and good. The only uncertain variable is the air flow.

I realized just now my humidity was 75% in my tent but air was circulating. I turned the exhaust fan on a bit. I think I’ll run my cloudline t6 on level 2/3. Get the stale air out. But keep my humidity high. Nothing is the worst then a quick dry.
