WillC said:Paul - There are many ways to water plants from both the top and bottom and via wick systems. Why is it that you prefer to water from the bottom? There may be a better way to accomplish what you want.

Fungus gnats are a sure sign of contaminated potting soil and not allowing the soil to dry deep enough into the pot. Bottom watering is not a very good remedy for that.
I suggest you remove any loose soil from the top of the roots. Then, allow the soil to dry as deep into the pot as the plant will allow - usually almost to the wilt-point. Then, water from the top using just enough water so that the plants dry out deep into the pot again within a week. That probably means less water then would be needed for water to run through the drain holes. When you water from the bottom, it is very hard to tell how much water has wicked up and how high.
