I usually check them once a day, usually about 2 hours after lights on is how my schedule works out. And usually just to make sure nothing's leaking or on fire.
When the wife gets home from work we go hang out with the plants so she can wind down from the day. I make up stuff to do just to be in there!!! Last week I installed a central wet/dry vacuum so I only need to connect a hose and flip a switch to keep the floor clean and the girls and I can still hear the stereo! I also use the vacuum to remove the runoff from the trays after watering.
Today will be spent vacuuming, preventative spraying for PM/mites then wiping down the entire room with bleach/soap water, cleaning the cool tubes, cleaning fans yada yada yada.......
