I purchased a humidifier at Walmart for my grow tent since the RH was so low (-20%). I used the humidifier for over two weeks and it worked wonderfully, you can actually see the humidified water coming out of the unit. Last night I filled it all the way up and ran it on high (The box says it is supposed to run for 46 hours). When I came in this afternoon, there was no water in the unit but it was still set to run, so I unplugged the power cable, filled it back up with water and turned it on. Since then it doesn't produce any visible steam anymore like it used to. Did I break it by running it with no water? This happened before and I went to Walmart bought the same one and took the other one back. xD (Sneaky, sneaky). Is there anyway to troubleshoot this issue? What in the humidifier actually produces the mist/humidified air? Or should I just go buy another one at Walmart and take this one back?
i dont understand why people want humidity in their rooms can someone explain? other than when your plants or super small why would you want more humidity?i spray my plants 2-3 time a day when they are vegging and thats about it , once flowering starts i turn on the DE humidifier
Relative humidity helps with maximizing potential. It especially affects the smell of the finished product in my experience. The downside is if it's not dialed in correctly and managed properly in flowering it seriously increases the risk of bud rot (botrytis). That being said, Chaz buddy you really aughta listen to RR. Your plants are about where they should be after 10 days of veg not 40. That's not caused by humidity. RH is something you work with to fine tune one of the six major requirements for growth (air, nutrients, water, light, temperature, and space - both above and below ground level - are the six if I remember right.) Needless to say, pests, diseases and fungus problems are not included in that list. Those sorts of problems are generally caused or encouraged by mismanagement of the six main requirements, and their effects cause or exacerbate problems in the six main requirements. Think of them as causes or effects of problems in the six rather than an additional requirement. Air is not your main concern right now. Plants only grow as quickly as their most limiting factor allows and right now your most limiting factor is water. That's where your energy should be focused. Have you read the grower's bible cover to cover? A pdf version is available on this site. You should really do that asap... it'll cover all this sort of basic stuff. And by the way... MEMORIZE THIS POST. SIX FACTORS NOT INCLUDING PEST/DISEASE/FUNGUS AFFECT PLANT HEALTH AND PLANTS ONLY GROW AS WELL AS THE GREATEST LIMITING FACTOR ALLOWS. This rule should dictate everything to do with how you manage your grow. The process of fine tuning growth in ANY plant life can be simplified to searching out and eliminating greatest limiting factors. By the way, that growery info for temperature ranges is inaccurate. 78 degrees is something of a hard cut off point for metabolic rates. Respiration drops off significantly at 78 degrees (the stomata close up), which is why most people keep their plants in the 70-76 degree range. It should never be above 80 in your room if you can avoid it. I have also never heard of people raising their temperatures by ten degrees if they're injecting CO2. I call BS... You'd only intentionally slow air exchange rates if one of the other factors is limiting growth so badly that your plants are suffering from CO2 toxicity (which is a super rare problem by the way), and even then that problem would be better solved by turning down the CO2 generator or fixing the limiting factor rather than gimping your plants. The plants might be able to HANDLE higher temps with CO2 injection due to a more optimal environment, but that's no reason to turn up the heat. Long story short, read the bible, this site and icmag.com for advice. Don't just grab anything off the internet.
thats probably why my seeds once planted take a while to get going because my humidity is usually 20-30% during veg and 40% during flower. I know 40% is good for flower but im going to try and bump it up and see how it goes. I know clones are supposed to be in close to 100% humidity so it makes sense
All shit is now straight, I have perfect water that I can create (R.O.), I severely dropped the nutrient levels I was feeding at as you guys suggested and it saved my Blue Dream. I may have held them back 2-3 weeks, but oh-well, I learned a lot about plumbing and RDWC. I bought the humidifier from Walmart a few days back, only 56$. It's keeping everything right around RH 40%. Which works well for me from what I can tell. All the plants now look extremely healthy. Wait till week #3 update is posted, a total 180 degrees turn around. - My only predicament now is how to automate the two separate single buckets. (More info in my grow log) - Sounds good man. Thanks for your advice, and honestly, no I haven't read the growers bible. I will do that for sure though. I almost got everything dialed in.
Wrong assumption. It ain't RH that stunts or retards growth. Both you guys......RH IS THE LEAST OF YOUR WORRIES. :bong-2: btw... 20 zips off 5 autos in a tent? :eusa_eh:
I call foul!! Was that a "replacement" scale? Did you weigh it wet? I just don't believe it. I have a hard time doing 4 per plant in DWC with good yielding strains. I know I suck at this but, come on.
Yeah, RR you seen them too bud.... He does have a thread on here. They were those beutiful Auto White Rhinos, he grew that were huge under HPS and LED lights. All the Purple color in the tent from LED's. Although I dont think they were Autos Because he started his 2- weeks earlier then mine AKR's, and finished 2 weeks later then mine. But still impressive grow, no doubt he got those numbers. http://forum.growkind.com/showthread.php?t=44944&page=10 O and the humidifer thing, seems like an Ok idea, as long as its doesnt go over 65% humidity, then its bad fo the room. Good stuff to read from experienced growers, about the knowldge of Humidity. And i Like the towel over the fan idea, It would kill me as im in Florida, lmao. Gnats would it that shit up. :roffl:
I read that article about humidity , and it still doesnt make that much sense . well the article i guess does, but then what you said res is what i dont get . It says a low RH can cause stress, so are u getting at that even though it causes stress it doesn't stunt growth , because i always though stress = abnormal growth , either stretching or stunting. Lemme Know res! edit: bronc i believe they were auto rhinos
RH is something that should be dialed in... eventually. At the moment though he's putting ice cubes in his control tub to try and keep water temps down and that's much more stressful on plants than having the RH too low. Having RH fairly high in veg isn't a huge problem from what I understand, but the main reason you don't want it high in flower is because of the mold risk. If you're handling mold other ways then I don't think it would be as big of an issue, though I just preferred to keep it low and not have to worry. Bud rot is a heart breaker. I personally never had a problem with RH (I ran smaller grow boxes with CO2 injection and slower air exchange than most) so I don't know how much it stresses the plants from my own grows, but I have had other friends manage it and in my opinion the bang for your buck on those upgrades is less than most others. If I remember right the plants can handle most of the stress caused by low RH by drinking more water through their roots, so having good humidity is preferable but isn't as big a deal as, say, air circulation or heat problems. Again, though, I never really had a problem with RH so I don't know as much about it as I do some other topics. As for seedling growth, I'd assume that you'd see much more effect if you got them off the floor or put a heating pad under them. Don't know if you're doing it or not already but that is usually the single best thing you can do to speed up growth rates at that stage. Clones NEED high RH because they're getting all their water through their leaves rather than their roots, but seedlings don't have that problem.
