Humidity problems

[bounty29]

Here's my situation. My cabinet is in my bedroom, and my plants are growing great. I've had high humidity, but it hasn't been a problem until now. I've got a nice little group of gnat flies growing in there. Buds are starting to bulk up a little, and if I let the humidity stay where it is (70-80%) I'm sure I'll have problems with mold. Right now I have a dehumidifier, and a box fan. Also, I don't have any fans in there right now as it's a bit overgrown and there isn't really room.

If I run the dehumidifier, I can get it to around 40% at the lowest, but it makes the temps go up to 85~

If I put a box fan in one window, blowing out, and have the other window open, the humidity stays the same, (70-80%) but temps can get as low as high 50s at nighttime (lights on for my plant is 4pm-4am.)

If I have the window open to cool the place down, it brings in the high humidity, negating the effects of the dehumidifier.

My apartment is like half basement, so the bottom 3 feet of walls is below ground level, contributing greatly to the humidity problems. (It was nice though, kept the place generally cool in the summer, and I'm sure it'll be a nice insulator in the winter.)

My thoughts are if I buy an AC, it'll bring temps down greatly and humidity down slightly. If I run both the dehumidifer and the AC, I'm sure I'd be all set, but I don't think I can put the dehumidifier, AC, and my grow cabinet all on one circuit.

Any ideas? Anybody with experience in a similar situation?

I prefer to veg at 80-85 F and 70% humidity,it's great for vegging plants and a nightmare for spidermites.75 degrees F and 50% RH is just another forum standard,and I bet the spidermites love that particular one.In flower you will have to dehumidify,after 3-4 weeks.Keep RH high during the stretch and feed plenty of nirogen,you're still vegging for several weeks into 12/12.I would run the AC and dehumidifier at 40% RH after 30 days 12/12.EDIT I almost forgot,those little flies could be fungus gnats.Check your soil for little clear worms(fungus amongus larvae).

They're definitely fungus gnats, the high humidity is keeping the soil moist for a long time, I just went 9 days without watering and the plants could've gone a few more days. I'm going to the local garden shop today and getting some sticky paper for the adults and I'm gonna try to find some Gnatrol or something like that.

hahaha thanks GN, I look for something similar to that. I thought the censoring was a bit off, aren't we all adults here? We've seen the words before, right? Oh well, as long as the knowledge and information keeps spreading I'm happy.

BT subspecies israelensis , for fungus gnats....Gnatrol, Mosquito Dunks, etc....

Beneficial Nematodes are killer effective with FG. Get rid of them quick, they eat your roots and transmit disease to plants. Sticky strips will not get rid off them.

Can you duct the back of your dehumidifier to direct the hot air out the window?

 

[bounty29]

HeadyPete - I was thinking about ducting the hot air out, but isn't the hot air coming out also the dry air?

I just got back from the garden shop, and got a pack of the sticky papers, stuck one in the ground in each container, to grab all the adult fungus gnats, and I got a pack of mosquito dunks to treat the soil with to kill off the youngins.

I also managed to fit a little fan in there, hopefully that'll help out some.



You can see the little sticky strips on stakes in the soil.

Hi bounty, I've had some humidity and heat problems in my cab...mostly b/c I use co2

I ended up getting an a/c, which brought the humidity down in the 60's, and then I added a small dehumidifier, the kind you use in bathrooms and closets, which brought it down to as low as 45%. It only holds something like 32 ounces of water, so I have to empty it about once a week, but so far it works great, only raises the temps a degree or two, but the a/c takes care of that.

Search ebay for the air and water store, they have a good selection of mini dehumidifiers.

Good luck w/ that humidity, it's a killer!

lol I don't want to bash any holes in the walls, let's hope it doesn't come to that!

I don't have a problem with odor, because the dehumid is in my bedroom, and so is the cabinet, but there's a carbon scrubber on the exhaust in the cabinet so the only smelly air is inside the cabinet.

If I have to, I'll run an extension cord down the hallway, but I'd rather not. I'll have to ask my landlord about the circuits, I think dehumid + AC isn't a suspicious reason to ask, so I'm not really worried.

Any way to figure out circuits w/o seeing the panel though?

 

[bounty29]

Those are some good points, I know there's probably some spaces in the apt. I haven't looked in yet. I'll check those out, and yeah I guess drilling a hole just big enough for an extension cord would be real easy to fix, heck, I built a cabinet that grows marijuana, right? What's a little hole in the wall?
