With HPW Complete you will need to freeze the mixture in ice cube trays. It will freeze hard and cannot be scooped out of a larger container as you can with Original HPW.
You need to offer a wide variety of fruits and vegetables with the HPW Complete as well.
I would not offer any bread. It is very high in phosphorus and does not add much nutritionally for gliders.
You can put the frozen HPW Complete in the cage a little before your gliders usually wake up, it melts quickly so the gliders can lap it up when they get ready to eat.
Another option is to mix only enough HPW Complete for a few days at a time. You can store it in the refrigerator after mixing for 4 or 5 days.
If you make a full batch it will need to be frozen though.
