I just dug around some of the containers last night and also found what looks like small centipedes! They are brownish, very fast and about a half inch long. They are only in a couple containers in one corner of the room, but what are they? My first thought were symphilids, but the only photos I've seen of symphilids are white and a bit smaller that these.
I've grow this strain regularly and the only thing different this round was the soil (from
FFOF to Sunland). I've pH'd the runoff and adjusted accordingly so its not lockout. Nevertheless I've flushed the plants twice now, once with
clearex. I've applied an entire bottle of Azatrol to little effect. The dunks were pretty effective as long as I crumbled about a dunk and a half over each five gallon container, and then watered in with dechlorinated water. I would like to try SNS203 as a drench, but that would be quite expensive. I run 8k organic medical for multiple patients. Thats 128 five gallon containers. At 2-4 ozs of SNS203 per gallon at 100$ for 128 oz, that would be the most expensive treatment for something that would have to be applied a few times to completely irradicate the gnats.
Another problem is that I have just transplanted most of my mother plants to this soil. I've had great results with it outdoor, and I know the owner of the company so I get a great deal on pallets. Good soil with good drainage, but I've never seen a fungus gnat infestation like this, especially with little centipede things.
I am going to go ahead and harvest with the moon, but in the future I think I will try a combination of predatory mites, either Hypoaspis miles or Gaeolaelaps gillespiei, with some parasitic nematodes. Rincon-Vitova offers a pretty good selection of beneficial fungus gnat predators.
Seamaiden, have you tried using Oasis HortiCubes? I have always had a good success rate with them. Even in the middle of a gnat infestation, the gnats seem to have no interest in my cuttings. I use the 1.5" cubes that come in sheets of 50. I line a tray with a little pearlite, place the cubes on top, wet the cubes with RO water with a drop of
superthrive and a couple drops of liquid kelp, let some of the water drain out, then cover with a humidity dome with the air inlets all the way open. My veg room is around 70% humidity. Takes about 14 days for the roots to really poke through, but my last batch lost only 5-6 cuts out of 150 with gnats flying around.
