Sir...
Good idea. Makes cleaning the bottom so much easier and you have the benefit of the plants without having to try to vacuum around them. I use small plastic pots with the holes in the bottom. I put an inch of pea sized gravel in the bottom, then two inches of organic potting mixture, I always trim the plant roots to an inch or so and put in the plant. I top off the pot with another inch of the gravel to secure the plant and then ease the pot into the tank. The potting mixture nourishes the plant for several months, then you can use small nutrient tablets. With regular water changes to replenish trace elements, the plants do very well.
