OK, plus is the same thing as complete. ONLY complete is add water only.
you can get bee pollen at a health store, maybe a big grocery store for about $10 a big bottle. you can get eggs for $2. the last is raw honey. this is harder to get, about $40 a gallon will make lots of HPW plus. I guess in a squeeze you can use regular honey, it just is not as good as raw honey.
follow the instructions to make critter love plus, your gliders will LOVE it.
We used complete. we got some gliders that came with plus. so we decided to make it up (it is cheaper then complete and we got it for free), really is not very hard to make. we put both in the cage and the gliders eat all the plus and non of the complete.
