Water crystals are a great way to give water to your dubia roaches, Madagascar hissing roaches or any insect (e.g. crickets) that can not have standing water due to potential drowning.
1 oz of Water Crystals makes over 1.5 gallon of gel water.
Lasted awhile will buy again
These water crystals have lasted me FOREVER and can rehydrate if you simply re-add water!
No instructions on how to use these, not even on this site!
Just need to provide some calculations about ratios so you don't have to do the calculations yourself or look them up. Overall it is a good product
