Yeah I've been using HF for almost 2 years now and I do get some fungus gnats but not as many as people make it sound. I got some yellow stickies in there but they don't get filled up or anything just a few on each side maybe 1 or 2 floating around the tent till they find the trap as well. I had 1 bag that was pretty bad but other than that it's been very minimal. Hopefully I can switch away from it at some point. I keep talking about doing it but it's just so damn convenient, cheap, and easy for a noob like me to not really have to do much and still get a QP per plant. I'm ready to explore other options and that's why I chose the BAS 3.0!@Hotfire , be prepared, HF usually comes with critters. Any new HF I buy for use in the house I usually do a good cook in the oven.
