How to make your own dry box
Why does the camera lens get molds?
Molds love to grow on DSLR lens coating as they love growing in warm, moist and humid places. Generally, molds will grow when the relative humidity (RH) is more than 70%. And there is a very specific type of molds which can only grow when the RH level is less than 20%.
The most ideal RH level to store the camera gear is between 40-50%.
The RH level at my home during winter time is around 75% and I use a 20L dehumidifier to help reducing the RH level. Unfortunately, dehumidifier is expensive to run, so I had to find a cheaper alternative.
My friend suggested a dry box with silica gel & hygrometer. I shopped around and discovered that dry box for one camera and one lens is quite affordable. However, if you have more than one lens, dry box can be quite expensive, it costs more than $100.
If you don't want to spend a fortune to purchase a dry box, why don't you make your own? Making your own dry box will cost less than $60

3. Hygrometer Digital Hygrometer Dry Box on the market More
Note:
When you use the dry box for the first time, put the silica gel & hygrometer inside the box and keep the box empty & airtight for a minimum of 6 hours.
The reason?
Because when the silica gel is used for the first time, it is in full strength means that it will absorb the moisture in full capacity making the dry box drier than anticipated.
It is based on my friend's personal experience, he put his camera & gear inside the brand new dry box & silica gel; and he found out that the RH level was 35% (too dry). After several hours, the RH level stabilized to 50% and stayed around that level until the silica gel needed to be recharged / renewed.
Making your own dry box
Three essential things you'll need to make your own dry box:
1. Airtight container
2. Silica gel or small wireless dehumidifier
3. Hygrometer
1. Airtight Lock & Lock Container
Choose the right size container that will fit all your camera gear (camera & lenses).
The airtight container will prevent the outside air to enter into the container hence maintaining the right RH inside it.
Place the sealed container in a cool dry area
Cost: Start from $8.00 from Amazon or less than $20 at any of your local / DIY store

Tips On Hygrometer
A hygrometer is a simple device that is used to measure relative humidity. Yet as simple as hygrometers may be, they can be quite delicate, and prone to giving inaccurate readings over time or with use. Using nothing more than a few kitchen supplies, however, you can determine the accuracy of your hygrometer, and calibrate it accordingly.
Easy
Instructions
Things You'll Need
•1/2 cup of table salt
•1/4 cup of water
•Hygrometer
•Ziploc bag
1.
o1
Mix the salt and water in a small cup, stirring until totally saturated. After a few minutes, the mixture should resemble wet sand.
o2
Place the cup and hygrometer in a Ziploc (or otherwise resealable) bag. Keep the salt and the hygrometer completely separate.
o3
Seal the bag and place it aside to sit at a consistent room temperature, away from drafts or direct sunlight. Let sit for 8 to12 hours.
o4
Check the hygrometer, while keeping the bag completely sealed. In ideal conditions, the humidity should read as 75 percent. (Your hygrometer may be off by a couple of points.)
o5
Remove the hygrometer from the bag. If you can, quickly adjust it to read 75 percent; otherwise, simply make a note as to how much you need to adjust your figure for each reading.
