I recently purchased a gardeina and got some miracid from miracle gro. Going on week 2 and so far so good. I got her gnats down to one as far as I can see. I picked out the healthiest looking of the bunch, so hopefully I can get some flowers this year. I also use flower thrive on my violets, datura, flowering shamrocks, cyclamen and Christmas cactuses once every monday to keep them on a schedule.
