I am about to do some updates on the veg room. I had a gnat problem that came in with the FF soils and was allowed to thrive, and as a result I have lost some plants. Out of the bunch of new seedlings, the PD's have done better than any of the others... no clue why, but it is what it is. After hitting the gnats with everything known to fight them, I have finally broken the life cycle and they are going away, but not without damage and a lot of lost time. Never again will I ignore the little pests, thinking they are no big deal. Apparently in the numbers I was breeding them, they are.
