Thanks

I had yet another sprout turn for the worst and show this infection/infestation. It was exactly on cue when the third set of leaves came. I hadn't started to use insecticide on the room yet, when this sprout was growing.
Now I have quarantined the infected plants and now have new sprouts coming up with (mostly) different soil. I have sprayed the grow room with insecticide and neem oil. I got weather proofing for my door coming, eucolpytis oil coming and diatomaceous earth on the way too.
How do I avoid this horrible nightmare again, that has cost me so much time and seeds? I am planning to raise humidity with a humidifier and I'm keeping temps in the mid range.
I feel pretty confident that I am getting back on track...
I supose bugs will HATE my garden area with all the neem oil I sprayed in there and I've also sprayed the following which should kill or repel most types of bugs for 2 weeks!
