What is and what should never be
Like Av mentioned, you can always mix up as much or as little as you need. Just scale your Trich to water ratio accordingly. I'm just about to the point of needing over a gallon to water my collection with. Granular is always an option too. When I'm running short on time, I'll just sprinkle it over my plants instead of mixing up the flowable.
