Is 67% Rh too high to dry?

I have a room with plenty of airflow, with a cool mist humidifier on a timer. 30 on 30 off. If not, the humidity gets down to 30-40%, which is too low. Right now it ranges from 55% to 67% relative humidity and 68-70 F. A lot of others grows I've gotten a little "hay" smell the first week or two of jarring them. From what I've researched, this is from drying too fast. So if it gets to 67% peak every now and then is that too high? The room has positive pressure with plenty of airflow (not hitting nugs directly). Humidity entire flower was kept under 50%.

I am also using the Caliber IV hygrometers.

Here's a few pictures of her at 8 weeks. Flushed 7-10 days or so and lightly fed before that. 250watt and 2 gallon smart pots. Top fed with coco/perlite for medium. Some of the pictures of the other two girls were from 7 weeks I believe. Waiting for them to ripen/amber up and swell a little more before I get those two.

First of all, your plants look fantastic. Well done.

I'm inclined to think that you will be probably be ok due to the good air flow. I would be nervous about having the RH reach almost 70 but you might be alright. What are the temperatures during drying? One curious thing I recently discovered was that low RH can be offset by low temps. My last grow ended around thanksgiving and my drying conditions were around 39 to 41% RH and the temps were between 59 and 64 degrees. The colder temps really prolonged the dry time. My average hang time was around 8 or 9 days and I found that the taste was amazing before they even hit the jars. I think they could have been packaged and ready to go without any slow cure. Something to think about.

Ok. Thanks for the responses! I'll lower the rh % a little. I can't really get my temps below 66 in the dry room, but I will say the rh is mostly around 55-60% with the occasional 65-67% peak. I'm looking to dry around 8-9 days; that sounds perfect. I should have hung the entire plant together and manicured later, but I cannot stand trimming dry bud.

Did you hang whole plants hot sog? Or branches? I know everyone has his or her own methods to this process. And yes I have read the stickies on this and other forums about drying/curing.

I will admit it usually already loses its amazing smells by day 2-3 of dry. This stuff keeps getting stronger every day, and sweeter at day 2 so far. All that planning to get my flower room not to stink, and now the dry room stanks shit up twice as bad lol. Thanks again guys, maybe I was jarring too late in the past? I want to keep every darn terpine.

You want to dry the bud to about 62% moisture content, that isn't possible unless the RH is below 62.
And yes you are right. After I put them in jars with a hygrometer, if they rise above 62% I'll burp them in 30-40% humidity. I'm trying to aim for the 55-60% rh now, but I don't see how I can keep in this range without a thermostat for humidity (hydrostat?) sorry I don't know what they are called lol.

I ordered the humidifier weeks ago, and the first had a cracked base so I had to get them to send another or I would have had this all tweaked out by now.

i strive to keep my humidity around 65% to slow the drying process. i grew up with neighbors that had a tobacco farm and the tobacco drying barns are 100 degrees plus, 70-80% humidity but designed for good air circulation. as long as you have good circulation and air blowing over the buds to prevent mold there's only upside to a 3 or 4 week slow dry. then i drop the humidity to 55% prior to jarring and i use a pump n seal to seal the jars to further eliminate any mold.

Nice! My buddy just dried all his and horribly nute burned them and had too high tds and out of whack pH (his first grow), yet still had amazing terpines. The smoke was great tasting/smelling, but didn't get you extremely high. He dried around 55- 65% and chopped too early with no flush, but the end result smelt pretty damn good. It smelt better than it did while growing, that's for sure lol. He didn't even cure it because he didn't know how.

I'm just hoping now that it's been 36+ hrs hanging that it's passed the mold stage (as long as I don't bag it/jar it for a while). I've been keeping it as dark as possible, but haven't seen or smelt any agent Skully or Molder. I didn't rip open the crotch, but I've done enough guerilla grows to know what botrytis starts out looking, and so far it's the antithesis of molder.
