I recently purchased the GranDaddy Purple Auto seeds. I am in week 3 day 5 and I noticed the gnats the 1st of the week. I have treated a few times with reem oil spray and placed stickies.
My concern is the discoloration in the leaves and shining and curling. This is happening mostly on one out of 4 plants. One other plant is starting to show a leave edge curling.
Also allow the first few inches of soil to over dry before watering. Fungus gnats love moisture and thrive in damp soil. Allowing the soil to completely dry out will kill the larvae and detour the adults
Me too. I actually bought them to deal with mosquitos in my rain barrels. They were really getting out of hand and I was getting bit several times a day. We had several containers all around the garage and out buildings. I have had this one container of Bits in the shaker container for something like 7 or 8 years. It still kills them by next day. I already had them when I started growing weed inside and saw on this forum that they kill gnats. I drop them in a gallon jug and after an hour water the soil. My wife who tends the Mother plants and seedlings top dresses them into the soil. Both methods seem to work equally well. Its a fine product.
