I got an Apera PH20 and didnt know I needed a solution to keep it in. 
I did a lil searching around on here and read the instructions that came with it, and it says I can store it in a little of the pH 4 calibration solution that came with it. Will it be ok? Have any of yall that own one done that before?

I have an Apera PC60 and always store in the solution. It helps keep the meter in calibration and minimize having to replace the meter tip so often.

Excellent choice Grow Bro, keep it clean and the bulb wet during storage….helps with accuracy in a big way

Thanks man! Im slowly upgrading everything. I jumped in head first on the first grow with hardly anything I really needed. This next grow, I will be better prepared.

I started with 3 individual cheapo lights and towards the end of my 1st grow I finally upgraded to a wayyy better led. Slowly but surely everything is coming together. Thanks to all of yalls help and recommendations.

Storing in 4PH solution will be fine. It keeps the eye (bulb) from drying out.
I use the apear PH meter and stored in 4 PH solution for years. Keeping the eye moist is true for all PH meter.
