Unreconstituted powder and bacwa proper storage

Just ordered a big batch of lyophilized powders and bac water. How should I store them? In the freezer or just sa ref or room temp (hindi airconditioned sa morning ang house kaya medjj hot and humid sa morning). I usually just keep mine sa veggie compartment ng fridge but now that I have a big batch, I'm worried na masira sila bc of improper storage. How should I store my (1) lyophilized powder and (2) regular bac water. Thank you please help a girlie out 🫶
