Harvest & Curing pictures: wet weight vs. dry weight

[MedGrower]

25% dry weight from wet sounds about right for most gardeners, I bet. I have studied this on my crops when I do DWC grows and I tend to get more like 21% of the dry weight compared to the fresh cut wet weight, on average.

Yea rep from me too
Is 75% loss from wet weight an average? Have you done this weighing thing a few times?
I dont bother cus Im lazy but wish I could tell by looking... Im about 4 or 5 weeks away now and things are happening and frosting

Thanks True! Yes, I've weighed at least one plant from each grow, and 75% loss is my average. When the buds are wet, they've still got some stem poking out so I can hang them, and I snip all the stems off after dried, and before weighing again, so part of that weight difference is the stems being snipped right up to the bud.

Every time I harvest, I look at my wet weight, and wonder what my dry weight will be. Well, here's some pics to illustrate that. Basically, one loses 75%.

This is a hybrid I created, crossing Lowlife's Auto AK47, and Dutchbreed's Lowberry. Beautifully-colored buds, and the whole house smells like berries!

Hi Alaskan 1,

In your first post and attachments did i see correctly that first you had 230 grams and then it came down to 5.7 grams????

That would have been 57g Dr juice - You can roughly divide your wet weight by 4 and you'll probably get just a bit more than that number

It does look like 5.7 in the picture.
There must have been a spot on the scale because it was 57, not 5.7.
Otherwise....that would be horrible! Ha!

Thanks Blue! You beat me to it

high! nice bud & info! just harvested a thc bomb and weighed it just before hanging yesterday and it came in at 77g. using the 75% loss formula, should make mine to around 19.25g.. nice! could i maybe use that weight to determine if its dry enough to start curing on a mason jar?

High!

It's less risky to use the more traditional methods, a good rule of thumb is to check the RH (humidity) at harvest, if the cab (where you dry your buds) is 50% RH, it should take one day for every 10% humidity plus one extra day (so 6 days)

You can test to see if a stem audibly "snaps" (not a bendy feely snap, a sound "snap") - then they're ready to jar.

I always check the day after jarring, as often the buds re-hydrate and feel moist again. In this case i'd hang them out for another 24 hours.

You can get a mini hygromether for your jar - The ideal curing range is around 62%

You could also buy a boveda 62% humidity pack to put in your jar with your buds. That takes a lot of mold worries away.

All the best

That's just how I do it blue. However, when I let my stems get to the snapping level, they are too dry, so I take mine off the line just before that. I watch the hygrometer closely to make sure I'm never over 70 in the jars, and slowly drop to 62 or so. Simply weighing to determine weight would not be accurate enough to ensure correct dryness.

Drying and curing has been the most challenging part of growing for me. I have found that if I wait for my harvest to get to the "stem snap" stage before going into jars it is too dry at that point. Once it's below 62% RH I don't feel it will cure as well even if you try to use Boveda 62 packs. My method that has worked better for me on my last couple of plants is this. I let the plant get to the point where it's dry enough that you would want to water it. I then let it go for one more day and chop it down. At that point the leaves are droopy and looking sad. Then it's into the brown paper bag. I use the 1 day per 10% RH of the drying room as a rule of thumb. If the room is 40% RH then it's in the bag for 4 days. I take it out of the bag just before the "stem snap". I do a final trim if needed and then it's into jars. This has been putting the bud at about 68%-70% RH for me. I then work on burping the jars over the next few days to slowly bring them in the 62% RH range.

By letting the plant dry out for the extra day in the pots I get closer to the 25% dry weight to wet ratio. If I cut with a wet pot the ratio is much lower at 20% of wet chop. My last Pink Grapefruit plant was 120grams wet 30grams dry and my little 1 liter bottle Cherry Bomb just finished at 61grams wet and 20grams dry(she was very tight buds and I am very happy with the high wet/dry ratio)

This ratio/% seems pretty spot on.

I harvested my first grow - Cash Crop a few weeks ago. (See pic attached) It weighed out to 239 grams. Now dried and cured, it weighs out to 60 grams. I don't have a new pic of the cured bud, but that is a 75% loss of weight.

Nice to read this thread, after weighing to confirm the weight loss on my first grow. the discussion as a whole has been helpful for me as a new grower. Thanks!
