I have a grow room that is about 8x4. I am only using about a 4x4 space to grow. I currently have a AC Infinity T6 that vents outside. Right now my temps are about 80 and my humidity is 70-75. I have a 4" fan blowing air in.
I am thinking about flower and the fact I may need a dehumidifier. The room is built in the basement. Here are my questions:
I currently have a huge 70 pint dehumidifier, would it better to run that an dehumidify the air that is being sucked into the room?
Is that dehumidifier overkill for a room that small? (even though it is rated for the rest of the basement)
If I decide to get an inkbird controller, would I put the probe inside the grow room to maintain humidity, or in the larger room to maintain humidity (if that makes sense)
I am ok now I think, but once flower starts obviously I need to get that humidity down
Hey brother welcome to the group. When I had a tent I had to hook my intake hose to my dehumidifier like this
It will raise the temp in your tent but it will control the humidity. I never got above 85*f and humidity stayed around 50%.
Temps will go up but you would rather have high temps and low humidity than the opposite.
I have a 5’ x 10 grow room now and have to do the same thing. I run my lights during the night and they sleep during the day. I can keep my RH below 45% with temps around 78 when lights out.
If I don’t run the dehumidifier, the RH will shoot up to 70%. But, I also run an rdwc system.
Keeping your plant pruned and thinned out will also help some.
Yeah sorry about that,that’s where we dry our weed, or we can use it for a grow box. I’ve had it about two year but have only used it for drying. I’ll get some pics here in a min and show you what I’m talking about…
Is there a way u can box off a smaller area where the intake vents are at. Block off say a 6x6 are and have the dehumid in that area keeping the area in check should help for intake rh purposes. I have issues keeping my room in check during summer time
Do u have the probe at canopy level or close to that’s where to get best reading I have a 4x7x8 room and have a infinity t9 with the 67 controller and still. My rh inhouse is pretty high due to running portable ac and window ac units because my central went bad winter had no issues in that room summer is all issues. But winter has furnace that runs and is a whole home dehumidifier also. Basements are a bit more of a pain because of rh issues. Make sure u have plenty of air movement to avoid wpm issues and try an keep rh down as low as possible especially in flower
Yea typically in the winter here the furnace will kill all the humidity. I’ve moved both the probe and hygrometer around the tent all over ( canopy level, on the pots, above the lights etc) and the both are still anywhere between 7% and 10% different, but both have been consistent in their own readings. I know all of them are within a few percentage points accurate, I just don’t know which one to believe
Here is what I currently have going on. This may help you visualize it a little better.
I run lights at night and they sleep during the day. 10 pm lights on, and 10 am lights off.
That gives me time to mess with them in the mornings and helps keep my temps regulated easier.
I have two 6” intake at the bottom and one 6” outlet at the top. My 6” exhaust fan brings air in the bottom and out through the top. The pictures on my journal may help.
Do you have electricity in your grow room?
Do you have an exhaust fan carbon filter (for smell if needed)? You need a way to exhaust the air if you don’t already have one.
My carbon filter is near my ceiling to pull hot air out, right above my light and near my drivers for my lights.
It would help. Not sure that is necessary. I’ve used a hose and just lay the end of the hose next to the intake and it will dehumidify the room. You may have to play with how close the hose is or how high the setting is on your dehumidifier. I have to monitor and adjust all the time but it’s better than having bud rot or mold issues due to high humidity. I grow in hydroponics so if I can control the humidity anybody can.
My dehumidifier is in a 12x11 room and it’s hooked up to one of my intakes into my grow room. Hope this helps.
I can guarantee if you hook the dehumidifier up like I have it, you will see a tremendous drop in humidity. Your temps will rise some but like I said, better to have higher temps than high humidity. Good luck!
If you’re asking did I mount drywall to the ceiling joists…I did not. I honestly didn’t feel like hanging drywall above my head lol. However, the walls go all the way up to the joists so it is sealed in that regard. I also have insulated the exterior walls with Rockwool and then used the moisture resistant drywall.
Maybe after this go round I can seal off the ceiling. I’m always looking for ways to improve and automate my environment.
