Since I'm in the middle of harvesting right and curing right now I wanted to share a DIY with all of you...
I like the way Boveda pack work, but for the amount of flower that I want cured I would need a whole lot of packs and that comes with a price tag attached.
So I thought to myself "Keeping things at a certain humidity level has been done for ages", look at drying meat and fish with salt... There should be more information to be found on the interweb... And there is... Every salt has it's own critical relative humidity. ie, Sodium Chloride (table salt) creates a relative humidity of 75% when one uses a saturated salt solution. Now I'm not going to bore all of you with all the science, but for those of you that are interested I'll put some links down below...
The salt I'm using is Sodium Nitrite (NaNO2) which creates a rH of 64% @ 25°C which is darn near perfect for a nice long cure at room temperature.
So... What else do you need to make your own Humidity Control pack...
First take out the shot glasses and put 25g of Sodium Nitrite in each one. Add about 10ml of water to that and let settle for a couple of minutes until liquid is floating on top of the saturated salt.
Then, very slowly pout out the liquid so only the wet salt remains.
Now the sanitary pad... It has a layer on top that lets droplets through only in one direction, but allows for air to travel through in both directions.
Take the pad and draw cut lines on it so as to create squares that are a bit larger then the shot glasses.
Cut out the squares. If you look at the layer buildup you'll notice it has four layers.
We need layers 3 & 4. Actually we only need layer 4, but it needs layer 3 to have some structure as it is made of Silicone and is very stretchy without it. Separate the square so you are left with layers 3 & 4
Put the square (with the padding down) on the shot glass and secure it with a piece of tape.
Put the shot glass into your curing jar/bucket/container and put a small cardboard structure (I folded an open box from some leftover cardboard) over the shot glass. This way the buds won't touch the glass and con't come into contact with it.
Now fill the container with bud.
I bought several small hygrometers from Ali which can be mounted inside the lid.
Enjoy your cure
Edit: I forgot the links...

- A couple of shot glasses
- Sodium Nitrite
- A scale
- A sanitary pad (I'll explain in a moment
) - A spoon/scissor/sharpie
- A bit of tape

- Plastic barrier
- Absorbent layer
- Padding
- Top layer
