Hi all...well, long time no see! I'm back and this time I come equipped with a bubblebox. Yep...new proud owner. Just operating it for the first time. I would be interested in learning a few more things from the experts about operating the bubblebox...

For instance...

How much material do most of you use to begin with?

Also, I'm not quite clear about how long one works the sifts on the different levels. How do you know when to stop the sifting process and move on to the next level? Is it a time thing? A visual thing? Or do people sift - harvest and then sift some more?

Thanks for your thoughts!
