Arg! Looks like I will indeed be "toughing it out." Having viewed the plants again, and after having found yet another dead cockroach, I discover that there are indeed living spidermites that remain. I tried, but apparently cockroaches are wimps in comparison with spider mites. I would say on average there are a couple of spider mites for every dozen leaf sets (usually on the same leaf). I'm just keeping the humidity at about 75, temperature at 68-70, and eyes open. I have spent about 10 minutes every morning and night smashing them with my fingers, and I guess that is what I'll keep doing. I suppose I'll have to start keeping sanitation in mind with my arms crossing over those big buds from now on. Don't want mold on top of this.
