How to raise humitidy

could get a hot plate with a pan of water and boil it. Or, bucket of water in the grow space or hang some wet towels in there.
 
How big is your grow area? I use a Bell Howell humidifier purchased at Bed, Bath and Beyond (love the beyond part). It was pretty cheap and uses a soda bottle for water supply but I use a 1 liter bottle and it works fine. I have a small grow area so I don't know how well it would work for bigger spaces.
 
I stick a fish tank bubblier and air stone in a folgers (coffee) can with water and blow a fan at it and that raises my humidity pretty good. Or 5 or 6 folgers can of water spread out in your tent
 
Its tough to do anything really effective without a humidifier. I tried just about everything, then gave up and bought one. Then found out they are pretty fickle units that work sometimes and at others dont. I finally gave up completely. I did discover that my plants really didnt care in the end. My humidity hovers around 15 percent, but plants adapt and grow just fine anyway. There are more important grow issues out there, IMHO.

Hi Inuart88,

I have a very small tent I Think it's 2 by 2.5 so far it is working for me, but it seems that I am always thinking and adjusting everything about my grow, including the Heat and Humidity.

So this is what I have found out so far and today that may change, now remember this is in my small tent.

In my small tent I have 2 300w led lights, plus 2 cfl's. I can almost get away with not having a fan or humidifier in my setup. Depending how close ( in the early stages of plant life, Led was close) and 2 cfl's were also close, the temp would get up to 85 degrees, and humidity was 30 or lower, turning on the 2nd led, Adding the 2nd led was not an option.

So I read some more and find out for young plants-- 85 degrees 30% rh, was at the max for high temp and low humidity. Not really knowing what would work I bought a small 10 inch fan and a Vicks humidifier. After installing and adjusting the fan speed (3 speed fan) and Humidifier (high or low) with 1 led and 2 cfl's I can pretty much maintain 77 - 80 degrees and 42-52 rh and since adding the fan and controlling the humidity my young girls have really taken off. What affects the temp and humidity now is that during the day the sunlight come into my tent room and so the tent room and then the tent will warm up a bit.

Now that girls (Northen Light auto's) are about a month old I am trying to give them as much light as possible, It is one big experiment, a couple of times a day I will check the temp and rh, and this is what and where I am today. -- The led lights, (from the manufacturer should be 18 -30 inches away) Adjusting that height also will increase and decrease my temp and rh and I am at a happy medium with that. I am now adding the 2nd led light, for that I wait until the sun goes down, I adjust it a bit higher above the plants that the other led and leave that on overnight. The temp usually gets to 81 and humidity drops to 42, so far my 2 girls seem happy with that and so am I.

So for my first grow and responding to this topic, my point is this: You have to take the great information here, apply it to your personal grow and your environment. Finally, you have to love experimenting with your grow as much as growing, if that makes sense?
 
I have been the same way adjusting this and that but I'm kinda just getting to the point where the inborn end is 95% good and weed is a weed and it will grow !
 
I found a humidifier with a set able the that I could keep at 50 percent but it is cool mist visible is that bad
 
In the end you are hurting your yields! Yes plants will adjust to lower humidity but it will slow growth and overall yield. Most of the low humidity growers probably don't mind but when you see these 2 week old thick stem low and tight node sprouts running around this forum, you already know why! To each his own I'm glad you are able to adjust and still harvest great buds. Peace and positive vibes to ya!
 
If I understand it correctly you are asking if a Cool Mist Humidifier is a good thing? The answer to that question is yes, that is the best way to go because it adds humidity to the air but not the heat which is usually the problem for most growers. Like NA stated above, if you have to low of humidity you are going to hurt your growth rate, the same also holds true for to high of humidity which can lead to mold attacks; if you are not already aware, it varies at different stages of Veg & Flower too, as well as for during the daytime and nighttime of where you want you humidity at. You may not already be aware of it, but on most humidifiers that dial for setting isn't you setting it to how humid you want it, but rather how much humidity you are asking it to put out into the environment, you have to then decide how much to continuously adjust it; unless you have an environmental controller to turn it on and off for you as needed to keep you humidity in a set point range. Other things you might also want to note that when using a humidifier to make sure you clean it often, they make things for this purpose too, so you don't spread things in the mist, and use distilled water to keep the minerals in the water from later leading to other issues with it breaking down later on.
 
I can attest to the low humidity small stems. Even though I got a ton of buds the branches are starting to fall and I have to prop the big girls up.
 
Well I might have not has to get a humidifier may be bringing it back I checked my tent last night after turning everything off it was 80%-eh I couldn't believe I had to run my fan all night to correct it thinking about grabbing some small 6 inch fans
 
I read an article from the parent company Surna, you may know the company better is I just called them by their other name "Hydro Innovations" who stated "Water Chilled Cooling Systems can save up to 30% more on climate control costs" they have a really great article titled "Considering your Regional Climate when Choosing Equipment for Cannabis Cultivation". Which does bring out the important fact so many people seem to overlook, swamp coolers for example will work in some climates based on region than another, where an AC unit will work in other climates better than others, all based off from the humidity of the area you are trying to cool. All in all at the end of the day Surna is a company whose sole thing is building and designing equipment specifically to the cannabis grower from the closer growers to the commercial growers, and reading what they had to say about cooling and humidity helped me, perhaps it will help you as well.
