My first attempt to indoor closet grow.
Most insect invaders need a moist surface to lay their eggs. These are flying insect which lay their eggs in the top soil level. So if you put something on the top of your medium that dries quickly you will stop the insects from laying eggs. I use hydroton clay balls but you can also use perlite or even paper. I liky hydroton because it is breathable, and it doesn't float when I water.
