Hi Kassia!
It's my first year, too!
I've done 2 batches so far. I did perennials in January, a mix of perennials/annuals last week, and will be doing the annuals and veggies next month.
I already have sprouts in almost all of the jugs from the first batch! I'm terrible with record keeping, so I'm not sure if the columbines never sprouted, or if they sprouted too early and got killed during a recent chill.
This is the second most fun thing I've done related to gardening. (The MOST fun has been watching the crocus blooms come up in January. They're beautiful!
)
