Agreed about the pot size and the lights. If you could up to a 5 gallon it's not excessively big in terms of taking up space, and if you could up the light power I'm sure they'd like it. With watering, you could water less at one time, or at least ensure they are getting some drying time between being watered. You could remove the 1st screen in leu of a net and then use the screen for the 2nd layer?
Happy growing,
