How do I break that down to a gallon of liquid?

(Posted this also on a disease forum but thought I would get a quicker response here.)

If you are growing stuff like tomatoes, just try getting a cover, or a simple zip lock bag locked onto your pots with a rubber band to hold the bag in place.

I do it with my seedlings until they are big enough to handle themselves. Gnats only seem to go on egg laying sprees when they see small seedlings that are vulnerable.

ryse, be sure to read the attached label all the way through. It warns of several things, including that you must use enough water at each watering to insure that the active ingredient is distributed throughout the growing containers. Use it each time you need to water, but allow the mix to dry out somewhat between drenches. In other words, don't add to the problem by watering more often than you have to.
