Do your plants leaves start yellowing and die and fall off. Everyday you go in your room there is another 100 leaves on the floor. I used to grow nice plants then this started happening i can't get it under control . You might have root aphids , I've been mixing neem oil in the water that helped...
Do you have any exhaust fans what's your temp's at. Do you have to worry about smell at all, if you do you will need a scrubber . Looks like you got a good start.
