Destroy Fungus Gnats!

Fungus gnats are one of the most crop devastating insect pests that any indoor grower is likely to encounter - equally as bad as the spider mite.

They can be even worse than spider mites, because they do their damage well hidden amongst the roots. They can totally wreck the plant’s root system without you being aware of what’s going on amongst the roots.

At least with spider mites, provided you are watching your crop, you can spot them as soon as they appear. 

CX Hydroponics Tanlin is a biological control for Fungus Gnats. It is a microscopic crystal which, when eaten by the Sciarid Fly maggots, swells up in its gut, perforates the gut wall and kills the maggot.
