well I like to use ladybugs but my population is on the decline and they are impossible to buy during the winter around here. More as a prevention, I have gnats flying around in each of my gardens but they are not a problem yet.
One thing though is I had really bad germination rate recently in my veg cabinet, and when I dug in the 16 oz container today, I found 2 dead seeds ( I didnt dig any other containers because I think they might still make it) and when I squeezed them I could see white worms crawling out. I figured they were fungus gnat larvae but I am not sure. Whatever that is, I think it's the reason why none of my seeds have come out of the ground (literally over 100$ worth of seeds...) ... and it's not a big deal I will start a few more in a few days and use fresh promix ... most of those seeds would have been ahead of schedule.
But it got me worried, the last thing I want is my plants in my budding rooms getting unhealthy halfway through flowering from little bugger eating the roots or something...
