It is time to come clean. I have been having the worst experience of my growing career in the veg room since the last update.
The fault for this was all mine because I got lazy and failed to follow my own advice to never let commercial soil into my grow area before sterilizing it.
It is well known that Fox Farm soil, especially Ocean Forest, can attract fugus gnats while in the shipping and warehousing process. Not only did I know that, but I had seen signs of gnats in my previous grows using this soil from this supplier in this new space, and despite the warnings right in front of me, I ignored them. I was not afraid of a few fungus gnats, for I had always been able to deal with them before this by letting the soil dry out between waterings in veg and by using pine bark mulch on the top of the soil.
So I stupidly used the soil right out of the bag and lazily built my solo cups with it and my 5 clones and 10 more plants from seeds were put in that soil, along with a healthy dose of Dynomyco.
So, I started out with an infestation already in progress, and then I willingly fed that infestation with more fungi. The fungus gnat problem got much worse immediately upon transplanting, I believe because I was feeding them! Egads.
I tried SNS 203. It knocked them back a bit, but the damaged roots were not taking up enough water to be able to saturate the soil with the SNS more than once, so I went to spraying the area 3-5 times a day instead of overwatering. This again killed a bunch of gnats, but they were still thriving, and the plants continued to deteriorate as the gnat larvae continued to munch on my finest root hairs.
In desperation I decided to kill those gnats, whatever it took, to try to save the grow, since a majority of the seeds were gifts or sponsored seeds. I bought a hot shot and put it in the veg room to kill the fliers, knowing that the airflow would take the chemicals out of the window in the back of the room, not allowing it to get into the bloom room to contaminate the buds.
I also ordered mosquito bits and beneficial nematodes, and put up yellow sticky cards. It took a few days, but the gnats have now mostly been wiped out. The Durbans in the mother room still have a bit going on, but it is working in there too and those plants will be able to make it soon to the bloom room, mostly bug free.
Veg Room #1 is not in as good of shape; actually it is almost a total disaster. The young plants were attacked too soon by too many gnats and most of them were not able to develop strong enough roots to get out of the solo cups, not to mention survive or even be able to stand up on their own. I started 3 out of 5 seeds from the Do-Si-Do and the Wedding Cake, and at this point it would be better to start over with the 2 remaining seeds I have of each, instead of taking the next month trying to save the couple of plants that survived. I have ended up with 4 Poison Daddys and one Hippy Hash that look like they could survive... as I said, the worst disaster I have ever seen from plants that made it to the surface. It took a lot of courage and putting away of my ego as well as eating a good portion of crow to post this update, honestly documenting my colossal failure, but here it is... a classic example of what fungus gnat damage can cause.
Never again do I want to be in this situation. All the soil ready to go now has been baked in the oven and should be bug free. Never again will I fail to be concerned when I see even one fungus gnat and Mosquito bits are going to be a regular addition to my containers when building them for future grows.
