Bolt, if your wife enjoys research (and you're expanding your grow) studying up on root aphids will benefit your endeavors.
IMHO, its a subject that deserves proper attention.
Root aphids are becoming a cannabis plague. They have complex reproductive cycles and they're extremely hearty. They're also virus vectors and are said to be responsible for the current "dudding" epidemic seen in some cannabis varieties.
There are lots of ways to "control" them but full eradication is difficult and requires a multi system approach. Some claim to have had success with Imid, but more often than not, it just knocks them back. They're like the cockroach of the indoor cannabis world.
I'm overtired right now and I've gotta be up in a few hours but here's a few good starting points.

I included these as well since you're growing more than cannabis and it expands on the subject with some interesting history
