trying to understand this, and basically what i've come to if you're buds dry too quick you've basically missed the chance to cure them, am i right?
Hygrometers do measure relative humidity, not absolute humidity.Your growroom holds a lot more air than a jar. I thought I already explained that. If it still doesn't make sense to you, put one of the suggested hygrometers in a sealed container and note the changes. BTW, the hygrometer doesn't measure the relative humidity. That requires a small calculation and an awareness of the dew point.
As a side note, the condition you describe above - ie. lights go off, temp drops 15F and the absolute humidity remains the same - paints an extremely unlikely picture, as the humidity will surely increase due to transpiration, alone. This is not a guess. As such, I'm at a loss as to where this is going.

hmm, you talk as if this is fact. do you have any proof other than what you suspect? there are some people that would beg to differ, me being one of them, but if the're is any facts to what you say i would accept or receive it much better than what someone believes.basically..
people say you can recover them by adding a fresh leaf or eye of newt etc...
it may help a bit... but IMO they are never really the same as if you had got it right first time.
barebones point on the subject is to dry them slowly and evenly
As I've said twice before, there's not enough air inside a sealed curing container to make a meaningful difference in the readings. It's a lot smaller than your sealed growroom.Hygrometers do measure relative humidity, not absolute humidity.
Absolute humidity is the mass of water vapor compared to the mass of air, and it remains constant in a closed sealed environment (not accounting for things like plant respiration, humidifiers, dehumidifiers, AC, etc). If you seal a jar the mass of water vapor inside is going to stay the same, the water can not go anywhere.
The absolute humidity in your growroom can't stay the same due to transpiration. It's a fact, not a guess. We've been here, as well.When the temp drops in my grow room the absolute humidity stays the same, but the relative humidity changes as a function of the temperature. This is the same reason we get condensation outside as dew. As the temperature drops the relative humidity increases, until the air is saturated and dew starts forming.
To be honest, we're only concerned with what happens inside the jar and are happy to leave the meteorologic discussions to other forums. Thank you for the explanation; I'm sure that some found it useful. Now let's move on.Where this was going was to demonstrate the difference between absolute and relative humidity giving you a real world example of another sealed and contained area besides a jar.

You can say it as many times as you like but the chemistry applies regardless of volume. Change the temperature and you change the relative humidity. I suspect that since most of the volume inside the jar is marijuana (and not air) that it would have a dampening effect on the humidity swings (ie RH increases and the weed will absorb more moisture making the RH of the air lower, and when RH decreases the mj will release more moisture making the RH higher).As I've said twice before, there's not enough air inside a sealed curing container to make a meaningful difference in the readings. It's a lot smaller than your sealed growroom.
It also can't stay the same because of the dehumidifier and air conditioner. My point wasn't that the grow room is a static environment, my point is that when temp goes down, relative humidity increases, and vice versa. You can notice this in your grow room with a rapid change in temperature (up or down) despite transpiration.The absolute humidity in your growroom can't stay the same due to transpiration. It's a fact, not a guess. We've been here, as well.
Agreed, but I believe the meteorological discussions is applicable, not only to this specific case but to growing in general. I haven't got my hygrometers and tried this method yet, i'm just trying to anticipate potential problems based on my knowledge of how humidity works. Most people do not get the education to understand what absolute and relative humidity are and how they are affected by temperature unless they get a technical degree in the sciences at university. Even among the college educated I find most of them do not have a fundamental understanding of the science. I also see examples on this forum of people that do not understand how it works. I would hate to be checking my jars at 70* and see 55% humidity, only to have it shoot down to 30% and kill my cure when my grow room heats up, then have it jump back up to 55% when I check it the next day at 70*F. Also vice versa (seeing acceptable RH, then having the RH be too high during lights off, only to return to an acceptable RH the next time I check it). Neither situation would be good.To be honest, we're only concerned with what happens inside the jar and are happy to leave the meteorologic discussions to other forums. Thank you for the explanation; I'm sure that some found it useful. Now let's move on.

EDIT: I reread this and seems like I am coming off as a dick, which is not my intent. I appreciate the information you bring to RIU, and I just want to understand exactly what is happening during the dry/cure beyond simply following a set of instructions. So thank you for taking the time to post this information for everyone including myself. I know a lot of things, but I also know that I don't know everything and still have a ton to learn. With that being said I have left the rest of this post uneditted. [/EDIT]Forgive me for not explaining that most of the volume in a sealed container is taken up by the bud and its associated moisture. Seems pretty obvious to folks who harvest and cure weed, and it's, well, kinda the crux of the entire process. Please stop trolling this thread. We're not here to debate non-applicable constraints with someone with zero experience, we're not here to play games with the contents of your growroom, and we're not about to take anyone seriously who had to start a thread asking about controlling condensing water vapor in his own garden. Doing "this for a living" apparently didn't help. It's time for you to go back to Toke n Talk..
...my point is that when temp goes down, relative humidity increases, and vice versa...
I'll inform the press.

Why on earth would you keep your jars in your grow room? The idea is to keep them in a cool, dark, dry place, like a closet or the kitchen pantry.only to have it shoot down to 30% and kill my cure when my grow room heats up
I agree, but to answer your question, yea, I do. I am an environmental control technician. HVAC automation is how I make a living. Been at it for over 20 years, yea, I am just 2 days younger than dirt...lolperfect cure takes experience. nothin else. Science debate all you like its just funny if you read the last couple pages. Do you guys talk like that in real life?
listen lame, i didn't ask for your opinion and could care less for it, i was and i'm still looking for facts. don't know how you would answer a question that didn't request for your silly opinion; totally defeat the purpose for me even asking,stupid.do you know what IMO means?
obviously not .. or you wouldn't have made this statement.
you can beg to differ all you like, believe what you want and dry your buds as quickly as you can..
if you want proof look for it, I'm not your assistant..
personally I make decisions based on my experiences..
For a variety of reasons: family, friends, smell control, climate control. I can't be having a kid find a pantry full of weed. I can't be having anybody find anything or smell anything. I also can't live like a hermit and not allow people that frown on marijuana use into my house, because they include some friends and family. The environment is also controlled in that room. I know what the temp and humidity are going to be at all times. The temperature isn't much higher than the rest of the house, and they are not stored under the lights or anything. I think it is the best place to store it.Why on earth would you keep your jars in your grow room? The idea is to keep them in a cool, dark, dry place, like a closet or the kitchen pantry.
I was oversimplifying it to demonstrate the effect temperature has on RH. Ultimately simon was right about the relative humidity staying pretty constant despite temperature swings because the buffering effect of the marijuana.A psychrometric chart and a full understanding of enthalpy is needed to debate the who, what, where and when of the physics of humidity.
It is pretty much an exact science at this point. So the temp down, humidity up, is only part of the equation, there are several other factors that determine what will bring about a rise or fall in humidity levels, not always temperature related.
Way more than is needed for curing buds, but I am stoned to the bone and just had to chime in that factoid.
Love this thread by the way.
Peace

Experience is invaluable, but science helps us understand why things happen, and helps us do it better. I talk like that in real life.perfect cure takes experience. nothin else. Science debate all you like its just funny if you read the last couple pages. Do you guys talk like that in real life?
trying to understand this, and basically what i've come to if you're buds dry too quick you've basically missed the chance to cure them, am i right?
haha, you're too funny lame. if you notice that question denoted for an answer of facts and not fiction or what you believe in, you dick in a butt.Actually you did ask dumbass.. and you didn't mention the word science fact or evidence when asking originally which is why my opinion was given.
If you don't want someone's opinion then don't come onto a public forum asking fucking ridiculous questions everyone already knows the answer to because they could be bothered reading first.
This site needs a fucking moron filter. Oh wait it has one +ignore
