Humidity control

Well just had 2 months of rain and the buds are doing great, no signs of mold and about 2 weeks left to go. On the other hand lol, these are only my second attempt at growing and I am not sure I would recognise mold if I had it but there is no alien looking growths on the buds and they smell nice and spicy so I may be lucky. I sure hope so anyways, my first plant was a complete flop, either to very poor genetics or what I do not know but it was an unknown high CBD strain that has all the effects of smoking tree leaves. Now I have these 2 Green Crack and it is great from the one sample bud I tried and now have to wait for harvest to enjoy my efforts, lol a Christmas present to myself.

Damp Rid in a small room works well, its calcium chloride and sucks the moisture from the air, costs around 10-15 bucks for a small pail of it.

Another way is salt, a friend of mine uses road salt in a small enclosed area to help dry out flowers, He uses a layer a few inches thick and the flowers are in a rack suspended above the salt. Roughly 10 -20 for the salt, and is reusable,

I guess that Calcium Chloride is also reusable after it is left to evaporate back to its concentration?

I just wanted to warn you that using salt I’ve seen it working also the opposite way. It probably has to do something with its dew point, but last summer temperature got so high one time that salt used to catch humidity released all the water instead. There was extreme puddle and we was surprised how much water it can hold.

Interesting, I’ve seen it get clumpy and water form but I’m already changing out the bucket for new stuff. The salt is more used for drying flowers. Cal Chloride for dehumidifying rooms.

Its possible, the problem is the CaCl (Cackle) kinda melts into a mess so you get a chunk when done… Its commonly known as ice melt, so if you live in cool weather areas its easy to find the stuff, if not damp rid is found everywhere.

It works but I prefer a peltier style dehumidifier over using cackle. But if cost is an issue, you get alot of humidity control for 15-20 bucks.

Go to an Arts & Crafts store and locate flower drying silica beads. It’s roughly $20 for 5 Lbs and it is very reusable. When the blue indicating beads turn purple/pink, put the beads on a cookie sheet and bake on low heat for an hour, or until the beads return to blue, then reuse.

I use a dehumidifier plus air conditioning.

I just read this. Some of you in the market for a new dehumidifier may find it useful😄

I know this is an old thread about drying flowers, but because of the subject title still relevant I think. @Calyxander What were the best dehumidifiers from the article (it’s behind a paywall) . I just bought a Frigidaire/electrolux from Amazon. It was very highly rated there, so we’ll see how it performs. What does CR have to say? Help us NorthWetters out!

Being from the high desert, I tend to have the opposite problem. I need a good humidifier.

Sorry about that link dead ending. When I first posted it I am fairly certain that it worked. If I remember, a Frigidaire model was recommended. I had purchased (in early 2013) CR’s highest rated model based on the previous report on dehumidifiers in late 2012.
Sorry, I do not remember the specific model Frigidaire from the 2017 report.
This is the one I bought 4 1/2 years ago.
Still works great. Very satisfied.
I live in South Florida…I need it to work well!

No Problem, That is the older version of the one I just got. As far as I can tell they are the same except the new one has a different fan and digital controls.

Idealair dehu! Mine is over 15 years old and going strong. You can find them used for around $100. And never worry about west coast humidity again.

@LED_Seedz did you say you were a mold remediator for a long time?

i was exhausting my tent (and all the humidity) thru my ducting and was getting condensation building up on some windows upstairs and brushed it off as a poor seal on the window (it does have a draft) but after moving my dehuey upstairs to run the condensation went away fairly quickly, but now i see this near the bottom of the front door, the one with the drafty windows.

is this mold and if so what do?

Hard to tell from the pictures. Could be salt buildup as well or a limestone scale from the water.
Search for images of aspergillus mold, and see if your areas look like that. It is the most common and normally shows before turning to stachybotrys or the one known as black mold.

Because your door seems to be coated, this is considered a hard surface and can most likely be cleaned with a bleach substance.

It also could be just a result of high humidity on a water based coating on the door.

yes it doesn’t look fuzzy or anything like mold i’ve seen before, kinda looks like the door stain just got wrecked or something but i’ll try cleaning it to see if it comes off -> i read something about efflorescence? that said

“First, look at the type of material on which you see the white substance. If you see it on anything other than concrete or masonry it’s mold”

so i wasn’t sure but i can’t imagine it’s mold though because the humidity never really got above 45% upstairs but i also know nothing about mold

Looks like the water has stained the wood. This is normal for older hardwoods. rub a little butter or mayo into it and watch what happens.

A real dehumidifier is a must, I can easily pull 10/12 liters of water a day threw it,
when your at week 11/12 of plants the last thing you want is 50%-60%RH,

I would rather spend $100 on a good dehumidifier than lose 30oz of budz
