They make a chart called VPD vapor pressure deficit, it is based off temp and humidity, during most of the grow the ideal VPD is around 1.0. You can find these charts all over the grow sites just find one and download it or print it out. VPD is the ability of the plant to transpire in and out of the stomata on the leaves. Just think of it as being able to breathe better.

I put up a post on my grow journal last night, a picture of my fan controller that also calculates VPD.

I have never run a de-humidifier, a humidifier a AC unit or a heater in my tents, but I have a unique situation where I have a heating cooling duct run to a coal room that is pretty small in size, 16’x6’. Tweaking the vent easily keeps things in the green zone. However I do run 6 fans, my girls wave in the breeze 24/7. I think great air movement is far more important that a perfect VPD.

I just picked about 200 1/4” sized buds off mine, but they are only half way or less through flower. I did it based on the master grower @happilyretired recommendation to get bigger terminal buds. Not on partial harvesting. My experience has been that the lower buds are always behind the top buds because they don’t get as much light. I do many times pick a bud and nuke it them smoke it to see where they are at, and because after 2.5 months of looking at them I get antsy lol.

I cut off some terminal buds because they were starting to go amber. I’m drying in a box to try to slow everything down. It seems to be going pretty well. No hay smell and the fresh clipped grass smell is starting to fade. I’m day 2 into drying when should I be jarring them up so I don’t dry them too much. After 3 or 4 days of drying in the box I was going to throw them in a paper bag inside the box to rry to sweat them out slowly. I’m just trying to keep everything slow and low until they’re dry. Any suggestions??

Depends on humidity and how dense your buds are. Usually takes about a week. Check them everyday and when they feel right, jar them.
Use a mini hydrometer in your jars too tell you where they are.(takes the guess work out of it) If its over 62%. take them out for a half hour at a time to dry more.
If its too dry, use a humidipack to freshen them up.
Its better to over dry a little and refresh then to under dry and get mold. I would check them at least twice a day.

My suggestions would be try and get the box set up with some string rigged up to where you can hang the buds. Hanging the branches helps the THC stay in the buds rather than the stems. But it sounds like you are just drying bud so throwing them in a box or a paper bag works perfect I try t shake it up every now and again maybe once a day so the buds aren’t sitting on the same side and getting flattened. 60 degrees Fahrenheit and 60 percent humidity is a industry standard for drying. If you can keep the buds in the dark even better. I usually dry 10-14 days before I think about jarring. Sometimes you can get away with 7 days with a faster dry time lower humidity higher temperature. Which takes away from the quality. I agree with chavez over drying before jarring is better than jarring too soon. Adding a humidipack also makes a huge difference to keep them moist once they are jarred. All of this is just what I have learned through experience. Just my two cents for tips and tricks. So far I would say you are on a good track. Just try and wait more 7-10 days before jarring.

Happy Growing!

Looks good from here. That’s one of those Tangible things tho, touch, squeeze, feel, smell, time, take readings of Rh 58-62ish in a sealed bag/jar etc.

They still a little moist still kinds has fresh clipped grass smell. But when I squeeze the bud just a bit the smell come out. I’m thinking I have another 3 days in the bag I put that in a plastic bag to slow it down a bit a ripped a hole in it. I’m still learning though

Really need a Hygrometer, any will do, so you can see the directly adjacent ambient rh. I too get that smell a little right after dried thats chlorophyll breaking down prior to going in something to cure, here is where it really changes and improves.

I have one I’m sorry it’s sitting sound 48% currently.

48% in a sealed bag, and still moist? how long in this bag?
That’s a little too low, but if it still smells like grass, its probably still sweating the inner moisture. Drying and curing as slow as possible is the goal for the best results. (I know its been repeated 1000 times-but worth saying)

The last time I dried mine which was getting close to a year ago, I took down all the lights in my tent, then hung the branches from the roof supports after cleaning all the big shade leaves off them. I find that is the easiest method for cleaning (removing all the big stuff but leaving the sugar leaves before drying). Then I just turned my Infinity exhaust fan on the lowest setting with the temp setting off and the humidity setting at 60%. And put a fan in the bottom of the tent to circulate the air around but not blowing on the bud and when it got to a reading of 50% I jarred them put in humidistats and burped them when it got up to around 70%. Then when things settled in to 62% I started the final cleaning. I bought 8 gallon jars but already had 4, which reminds me I need to get 4 more lol. What I couldn’t fit in the gallon jars I put is a 5 gal bucket with a couple boveda packs.

Your bud looks great! How is the smoke? Surely you’ve torched some by now? Lol

@excommunicato I think you got this? Just believe in yourself now and under think, if that is such a phenomenon. Seriously, I think you got this.

I was going to wait until mid cure to try it out…but it stays lit when smoking so it should be ready for jars in a few days. This is the first real harvest I’ve ever had and I can’t say I did a bad job.
