Drying in a Sealed Tent, With a dehum+humid + small fan

[gubblebum]

So an expert grower told me something I find hard to believe is true and I just wanted to know if anyone has heard of this?

He swears he can dry inside of a sealed grow tent with no ventilation, just a dehum and humidifier, temp controlled. Rubbish? Personally i do in a tent with all of the above, and a very tiny amount of ventilation, with a ground level fan and open intake/outake.

Absolutely don’t think it’s rubbish, the humidifier/dehumidifiers move a fair amount of air (ventilation), so if you controlling temperature and humidity, it’s irrelevant if it’s an open or closed system.

Do you have any sources for this? I've looked everywhere as the guy who told me is a world class grower... but just can't find anyone doing this.

Loads of people do it, if he was so good he’d use an air con too to keep temps down, which in turn stops the flower excessively losing its terps. Maybe he’s got really cold ambient temps to begin with so he doesn’t need an air con, but dehumidifiers put off a fair bit heat.

maybe just telling you this doesn’t change ur mind so I’ll ask the question

what makes you think it won’t work?

answer this and we’ll be happy to educate you

The temp goes without saying What worries me is the potential for mould due to a lack of fresh airflow! As I said I can't find any source online saying its a good idea to dry in a sealed tent, but I'm exploring it since the person who told me runs million dollar grow facilities... but it's weird I can't find 1 source online!

Mold grows when the humidity is high. With the dehumidifier and the air flow it generates there's no high humidity and thus no mold.
"Fresh" air doesn't exist.

If he is running million dollar grow facilities and using tents, I have a hard time believing him. But if he's running those facilities and using sealed rooms, the equipment he's using is probably pretty expensive and specialized. As mentioned above, I believe the important part of the dry is keeping the temp and humidity ideal. I believe for most of us, the air exchange helps with the balance of those 2 parameters.

He's not using tents, he was recommending I do this method.

Gotcha. Check out the Cannatrol. Or, if you are a DIY kinda guy, check out the thread on here about converting a wine cooler to a dry/cure cabinet.

I'm not real sure that running a "sealed" tent is all that sealed. Therefore, you will most likely have air exchange happening anyway. Depending on how much you are looking to dry at a time, the 2 options above may be a good option.

Would love to see that thread if you have a link? I do use wine coolers already for curing, once it's finished drying I use grove bags and stick in the wine coolers, seems to work pretty well! Just wondering if I dare seal the tent fully next harvest since I do have decent enviromental controls. Humifier, dehum, inkbird dual controller and AC unit in the room.

I had read about these for a while before trying, this is not by any means a new idea nor did I come up with the idea. I was tired of over drying and drying too quickly in the winter, then freaking out about mold in the summer. A google search will give lots of other ideas, but I get a lot of...

Some of us here dry in fridges, so it’s definitely not unheard of. As for the airflow, “fresh” air can quite often be the culprit when mould develops, if you clean your space before drying properly and do your best to eradicate any spores that may be hiding in the tent or on/in equipment then seal it up and dry, you’re far less likely to get mould than if you were to follow the same steps but then draw unfiltered air into the space 24 hours a day as you dry the product.

the parameters within the drying environment should be set to optimal in both cases, and as long as these are precisely maintained then in my experience a sealed environment will actually have less chance of producing mouldy bud than one with air exchange, there’s just less chance of bringing spores in.

hope this helps
