Nope doesn't work that way.

Bud density isn't a factor in the madbud study. Starting weight and ending weight for safe storage are all that matter here.

There is a general consensus that bud looses 80% of it's weight when drying.
Personally, I find it to be higher.

I have not weighed individual buds. I have done it by the box. Which gives a better spread of the type of buds weighed. However, they are all on twigs to enable hanging, but off the twig for the final weigh in. 90% losses. As high as 93% when no RH meter was used. I have done this many times, though not since using RH as a guide. Which has led to heavier buds I'm sure.


Some pics here show strings put back'n'forth in tents, to hang from. I did similar but my strings are back n forth within a cardboard box. Typical sized boxes, like 30x30x40 so no entire frames being hung. 250mm 'trimming sized' bits at most, and just as many bits a couple of inches long. Roughly 5oz per box dried. This is a nice method for a few reasons, one being, you can weigh it.


Fairly soon I will be chopping 'trimming sized' bits off, trimming, and laying them in mushroom trays. This will give me chance to do a more modern weigh in.
I like shroom boxes/crates. It's a bit like hanging nets, but free from your local curry takeaway. They are designed to stack shrooms without keeping any damp in. I like to half fill them, but have got near the top before. Which is fine, as a day later it's half the size. I just stick um in the then empty veg tent, with a circulatory fan and extract set with an RH controller.
Methods like this allow bulk weighing, to assess what is going on. If that's what you want to do.

I will suck a lot of water out early on, with low RH, but not enough to dry the outer leaves. I want everything at 60% and never below, but see no gain in waiting to get there. It's days at and above 60% that count. Days at 70 don't count for any more than days at 60. It's just an extra day risking mould. So I get it down as quick as I can, without the outsides dipping below 60 from trying too hard.

I hope that's all relevant

Cutting the buds off and onto nets to dry i was closer to 80% shrink

To defoliate or not to defoliate?

Growing up I've always heard that you should prune away the big fan leaves to maximize light to areas & increase airflow. This was obviously 20 plus yrs ago & I know things have changed so after reading about it online I'm left even more confused. My plants are at day 40 of flowering & are chock...

If you want empirical data, then gather it yourself. Don't crowd source something like this when there are far too many variables at play.

Let's dive in. Just based on geography here are my knee-jerk big variables:

- Are we coastal or high desert?
- what season are we in?
- how much harvest weight are we talking about?
- what facilities do we have for this drying process?
- are we drying indoors?
- are we drying outdoors?
- what is our end goal?
- why do we give a shit?

the last of those points being the most critical. not trying to be a dick but calling me a stoner is bullshit on its own. I grow. I don't smoke. I'm also an engineer by trade, and if I know anything about drying/curing, it's that it depends. If you want to know what the perfect time is for your situation, then figure it tf out. you can't crowd source this data. mic drop

Not exactly a mic drop, although I see your point. It's the same point I often get from engineers; long, dull, precise and accurate, yet somehow doesn't help me in the slightest. I'm just breaking your balls dude, no harm intended. I'm a biologist that gets subcontracted for in situ remediation by envro engineers, been working with you automatons for years! But yeah, despite the variables, that are largely mitigated by simply applying a generic set of parameters like "say 60% RH" and maybe some indication of temp and air flow (fan/no fan), he can gather alot of useful data. Perfect data? Negative. Perfectly usable? Indeed. As far as crowd sourcing, I just call that increasing the sample size, which inherently makes the whole thing more reliable, so why not?

Need some volunteers with gram scales to weigh a 20-30g, fresh cut bud or stem and then weight after 24 hours drying at say, 60%rH and 65-70°f.

I'll try to do that. I've got another monitor in the mail coming, and a harvest pending. Might be able to assist.

Too many variables it will never work. What works is hang or brown bag until you can trim using fingers only. Perfect every time. Or you could wet trim a bud, weight it wet then dry it to constant mass and calculate moisture content. From there just dry the rest to 12% and jar. First way is easier and never fails.

I agree brown bags are good for controlling moisture release.

I’m stunned that i haven’t seen anything about weight loss on any of the forums i use. It took a lot of guesswork out of my harvest this year but really want to see more results than my dozen plants. Especially if they’re not drying at 60/60, the 80% weight loss may still give a decent cure after a quicker or slower dry due to higher or lower temps and humidity.
Click to expand...
I think your going to find that weight loss is highly strain specific, and grow specific. It's also developmental related, and a few different factors, I suspect.
Even down to the hydration status, when the plant is taken. ie. the pots wet, or dry. Some plants are simply going to dehydrate out of the gate far faster than others. Genetics greatly effect Density.

Most of all, grow parameters as well, temps, conditions, nutrition, sunlight.
I'll try to get some 24 hour information, but I think it will only be so useful.

Most of the stuff I've got coming though is very dense, and resinous. GG4x something else.... Several different cuts. I don't think it's going to lose near the weight I expect the old blueberry strain to loose. Probably not even in the same ballpark.

I mean that's basically what 8 pages of comments are saying if you wanna save yourself some time. 🤣

I just went through "dry" all the way to cure and some were ready to jar earlier than others. My weather has been up and down in humidity, and I kept the temp relatively close throughout the process. If the stem does not "break" I gauge it's not yet ready for jar. SS

@Aquaman, you can see what i’m working with, i wish i could test some big donkey dongs but alas, i grow pinecones and now i’m out of them.

Yeah its a worthy idea and definitely will shed some light and good information in the end.

My feeling though is not just start and dry weight... its also the water movement and time allowing the breakdown and conversion of chlorophyll, sugars and starches to other compounds. If dried to fast that cannot happen because the microbes and enzymes stop being active at a certain moisture content.

Fridate night weigh-in, cuts dropped from 12.1 to 7.4. The plant (including 18g cup) dropped from 127 to 102.4g. Unfortunately the ambient humidity is down to 50%, temp 18C. Also, the first jar is holding at 60%, maybe a 2% increase.
