Need some help please!

I am having a humidity issue. My tent is in a metal storage that is attached to my covered parking, so there is no floor to it. It just sits on the gravel. So it’s not a sealed room. I’m thinking dehumidifier would be tough for the room the tent is in. The exhaust is going into the room, but like I said it’s not sealed so there are spaces near the ground where air can escape. Would A/C be my best and only option? Humidity has been spiking up into the 80’s. They are 4th week of seedling phase.

How big is the tent? Vs shed?
Do you have room for a dehuey in the tent?

Do you anticipate high tempurature issues during the day?

Tent is 2x4x5. I do have room for a small dehumidifier. Shed is larger, not sure on the size

Exhaust the tent out of the shed.

My 4x8x8 is in an attached garage. I use a 50pint dehuey and it get the job done. Tried a 70 pint, but it generated too much heat.

Intake air temp and humidity have huge impact.

The gravel....no floor...makes me nervous. Zero experience.

Do you think that and the dehum. In the tent would bring it back down into the 60’s?

Yes.

Cannot say with any certainty.
If anyone can help it's @Renfro
Good luck.

What is the ambient humidity level? Size of the shed? Can you insulate the shed? Is it in direct sun light?

Ambient humidity fluctuates. The shed is in direct sunlight. If I had to guess on the size I’d say, 12x5 or 14x5. I have thought bringing in some dirt to plug the holes down by the gravel. There would still by tiny holes from where the metal pieces come together but the big ones would be closed

Bringing in dirt can also bring in pests.

Really it sounds like an uphill battle. Sheds in direct sunlight get really hot in the summer. The fact that it's not insulated and has leaks will make it difficult to keep the temperature and humidity in line even if you have an AC and dehumidifier in there.

Maybe pour a slab in there and spray in some insulation. Now you can run it sealed with CO2, AC and dehu.

Now I’m a brand new grower and thinking WAY outside the box here, but if I were to exhaust the air from the tent into a bag of charcoal would that help at all? Lol. I’ve read of a couple of people doing that to help with smell and such didn’t know if it would help with my humidity issue. And even if I can lower it 9 or 10 percent that’s an improvement.

If you are able, cut yourself a small intake vent (make sure it has some screen on it to prevent pests). That humid air has to be vented to the outside. If stealth is a concern, put a duct muffler after your exhaust fan which will quiet your exhaust air stream. Once you start pulling out the humid air you should see at least a 20% drop in humidity depending on the part of the country you live in.

Thing is, if he blows air out of the shed, air must come in to replace it. If that air is hot or humid then we have a problem.

Definitely plug all those holes to the outside world . . .don't let mother nature in your grow room (The Borg will come).

No.

Plus, lowering it a little now may be enough but what about later when flowering? Temps are gonna get hotter as summer does it's thing.

What if I got a small inline duct fan and either cut a hole in wall down low and installed it or got some ducting, dug out a space under the wall, and ran the ducting out of the shed? Would that duct fan do the trick?

I have a garage grow in Colorado. No AC. We are lucky here for humidity but not temperature. One of the ways to control your heat, when flowering, is to run your lights at night when it is cooler. Renfro is 100% spot on about getting your grow dialed in. I have crashed and burned due to high Summer temps and a fan dying.

Air out means air has to come in. Depends on the ambient humidity and temperature. If it's raining outside you will pull in more humidity than you push out.
