What does drinking red wine have to do with houseplants? Gnatnix™ Review

I am very fond of plants thus I often overwinter tropical plants to use in my garden the next season.  I am also fond of red wine.  Turns out I sometimes  have unwanted house guests who are also fond of red wine.  These unwanted guest can sneak into my home when I overwinter tropical plants inside during the winter months.  I am speaking of fungus gnats that sneak in with my plants.  These little gnats seems to love red wine so much that if a glass of red wine is left untended when gnats are around they will soon be swimming in the wine.   This is very annoying and also embarrassing when drinking wine with invited guests.  There are ways to prevent this from happening.  You could switch to white wine.  Gnats, like me, have a strong preference for red wine.  Instead of switching to white wine I have chosen to prevent the gnats from propagating.

The substrate is already available for the hobby grower, but currently Growstone is looking to widen it’s reach and transit into the commercial greenhouse market.

At the time the first trials were done by the University of Arizona, Paula Costa was a graduate student at Agriculture & Biosystems Engineering Department. “I was finishing my research project at the CEAC and very quickly got directly involved in setting the first informal greenhouse trials with Growstones crushed foamed glass in the Fall of 2005,” says Paula who is now Growstone’s R&D Director.
