Update:

Since I combined the N. Californicus [NC] (Good red mites) and the T Urticae [TU] (Bad 2-Spotted mites) in the same jar, threre are new hatchlings from both today.

The NC population looks like it increased, but not significantly compared to the TU population. The older NC eat 4-5 mites/TU eggs a day, and lay 2 eggs a day. About a day or two later the eggs hatch (in hot temps) and will become adults within a week time with proper food (currently about 30:1 TU:NC, about a week's food).

I kept the enviroment 80° and about 80% humidity for the first day and it worked out well. The very tiny newly hatched NC are running around the jar like mad, very active. I haven't seen any mite-killing action yet but I'll try to take some cool pictures once it starts.

I figure a sizable NC population to introduce to his room won't be ready for a week, so we used Safer brand Insecticide last night and he says the mites look like they are going through hell (temps dropped to 50° last night in his room) but the plants are great.

Applied science rocks...
