in my opinion Grove bags are the best thing since sliced bread.
Just as possibly soon as I can get bud dried to 60% there’s no better place to put it

Do you mean getting the RH of the container that the bud is in to stabilize at 60%?

No I mean when bud pulled from whatever Drying method can be bagged and will be stable at 60%

Ok, right. But what is stable at 60% (when you bag it)? The RH of the air inside the bag/container, right?
Meaning if you put a hygrometer in the container along with the bud, that it would display 60%. That what you mean?
Thanks.
Weird, my post was auto edited by the…forum.
Anyway, I guess I know what you mean, hygrometers in a container with the bud. I use a moisture meter now, but honestly, it doesn’t help as much as I thought it would. I use the environmental conditions, and other indicators too, in addition.
Thanks.

I think what he means is if your close to 60% and are using grove bags your safe to seal them up .

NO, what I mean is whatever drying method I’m using whether it’s hanging in a room or the Cannatrol when the bud can be put in a Ziploc and stays stable for an hour at 60% it’s time to go in a Grove . I like the way the grove works I trust it I know what it will do so all I’ve got to do is slow dry the bud to 60% and then place it in the Grove

How did this work for you? I’m interested in making one myself.

What do you use to measure the humidity, brand name and model? Thanks

Has anyone investigated using a DIY/repurposed vacuum chamber in the drying process?

What an amazing project @FieldEffect I’d no idea that you Banged this one out !!!
Wonderful stuff and I hope its been easy to leave in charge of the Harvest

Have you tried putting a small moist sponge in your jars like the cannatrol uses? The point being that the buds wouldn’t have to release water to bring the jar RH up to 60%, or at least not nearly as much, as when the air inside is <60%RH to start.

I’ve considered it. Life has me too busy now 
Yeah it’s been really nice. I’ve been running it the last two years, it’s super convenient. Keeps the house weed-aroma-free and I get great buds. Although I’m wondering how my outdoor run this year is going to stuff into there. The plants are getting…big

Hey @FieldEffect have you been tracking your drying and or curing cycles on any kind of monitor. I am really interested in the cycles of drying in the DIY units and Cannatrol’s. I really wanted to try to get all these different cycles people are running on a thread. I had this batch in my DIY dryer going on 4 days. This is my current cycles for four days. I anticipate this will be roughly 4 to 5 week Dry. I would like to see everyone’s cycles and when they reach certain RH numbers at certain times in the drying process. Your work here in this thread is Awesome . Cheers !!! Here is my graph 4 days into cure on my DIY wine fridge. I really want to see as many 30 day cycles as possible. I think the info will really show us differences in temp/RH at certain times or lack there of this could help us overall figure out ideal temps ect. Maybe even variations on temp during drying.
There is 4 spikes on the graph they were accidents lol. 4 times the door was accidentally cracked open and quickly closed lol. Long story is I have 2 identical units and got them confused lol. So the 4 spikes don’t count as drying cycles.
The cycle below is a full 4week dry and 4 week cure from my wine fridge dryer. I am running cooler than most people do. Curious what temps and time frames your keeping during your cycles.

I do have some data, I posted some here:
I’ll take a look at my files later today and see if there is some whole cycles I can plot.
Your RH looks really high for such a low termperature in your upper plot. I envy your temp stability and low setpoint BTW 
I’ve got a few thoughts on your lower plot, more reasonable RH range. I think the gist of what I’ve learned so far boils down to these things:
- Extending the dry to about a week has a marked difference on quality. Higher temps are an unfortunate reality of having my stuff in a shed, but I’m still getting great results.
- Scientifically, I’d want the most stable possible temp and absolute humidity to prevent gland expansion/contraction and eventual bursting.
I’ll get back to 'ya later

I converted a wine cooler to see if I could get Cannatrol like performance. After much testing, I took the same approach that I would take for a HVAC system for a museum.
I removed the coolers controls and replaced it with an esp32 connected to my Home Assistant.
The way I was able to hold very tight temp and dew point is by having the inside and cooling fan on all the time, using a modulating signal to the cooling module. This module ramps up and down chasing dew point. Inside the cabinet, I have 3 amp Peltier with a small heat sink on cold side that sits over drain hole and a larger heat sink on hot side that has a small fan on it blowing down, the fan is always on. I have a modulating signal going to heating module and it is chasing temperature set point.
As the humidity/temp changes, so does the dew point. As it goes up, the cooling ramps up, the temp goes down. The heat module goes up heating and drying air. After some time, it finds it balance and stays within .25 temp, .5 dew point,
Just finished a slope from 57.5 dp to 54 dew point over 4 days, then sloped to 52 dew point over 4 days at 67 deg.
Works great! I just finished programming/testing an external display. Now i just have to make a cover with wood or 3d print.

Should we create a thread were we can converse specifically about the engineering? A lot of you guys have EE backgrounds making your own eproms / firmware and boards etc. It would be cool if we could get something going where complete designs from the board to eprom and firmware with a parts list could be developed. Then one could just get the board printed, assemble it and program the unit.
Maybe crowd funding to help pay for the parts and the engineers time etc and be sure to give some of that money to overgrow to help support the team and their expenses.
I thought the AC infinity 79 pro was a good base but needed more programmability, wifi, charting and graphing like with a open source project grafana or something similar.
