I live in a very arid environment, and my average humidity both in my house and in my grow tent is lucky to be as high as 20%. I have noticed on my newer plants that the very tips of them are slightly brown. The same trait is seen on all of my houseplants, and I am assuming it is due to the lack of humidity in the air. My question is - how important is it to maintain a higher humidity in a grow area? I notice the day after I water it goes up to maybe 25-30%, but drops by the next day when any residual water is evaporated. Will this have adverse effects on yields or my buds? If I really need to up my humidity, any other arid-climate folks have any suggestions as to how to increase it? I am fearful of a very moist environment, for mold/bug reasons... peace GTWT :XXhippylove:
Humidity can have an effect on water and nutrient use of the plant, although I would recommend increasing ur humidity I would also suggest lightening up on the nutes just a tad, as increasing humidity may be difficult depending on ur setup and environment. When you say tent is it a plastic enclosure of sorts? In addition to puting a humidifier in there id also try to reduce the amount of air exchanged as much as possible without having adverse effects on temps. As for preventing an overly humid environment you can wire any humidifier to a humidistat. Plenty of peeps round here can help you with that. Enjoy
tents are the 3x3x8 zippity do black cloth/plastic?? types. mylar on the inside. not exactly air tight, i don't think. tents are set up in shed, so temps will be an issue soon, so i'm gonna have to keep air flow up, my main method of controlling temp. already eased up on the nutes, as my first grow kicked my ass. using alaska stinky fish poo & kelp. i can't really fit anything else in the tent. it was a bitch stuffing a heater in there during the winter, & i have a small fan hanging from the 'rafters' for air movement. don't know about adding any more noise that a hum. would bring.... is there any static/passive way of adding moisture?

if you have any room left in that tent you might try putting a bucket of water inside there might help some. :beerchug-2: Teamster6
Passive humidification = steam Although there would be added heat Really though in order to increase ur humidity to a point that's controllable you would need to seriously modify your setup. I would worry more about temp issues rather than humidity. Humidity is something to tackle once you've got everything else werkin. All the same make sure ur walls are insulated as well as ur roof. And try to seal it up as much as you can. Make sure your intake is low on the wall on the north side of the building assuming ur in north america. Make sure that ur exhaust is drawing from the highest point possible in the room. And be sure to vent your light seperately from your exhaust if ur using an air cooled hood. A small portable humidifier can be had a home depot for a hundred bux or maybe a lil more. Sounds like a fun project Ps I used alaska fish poop for a while, and found it to be a good additive every once in a while durring veg but otherwise not very good as a main food source. Aside from the smell...Yak... It'll work but id recommend using something else. in the end. I ended up using pureblend pro with great success. Both the veg and bloom.
