Hello, I'm still pretty new and about to start my first grow, so I just wanted to tell you that your log has helped me quite a bit. It's nice to be able to see what sorts of problems I might be up against. I bought the Ready Set Grow video from HighTimes, and while it does help it still leaves out quite a bit, especially in the trouble shooting department. Knowing that there is always a chance of aphids or spider mites, suddenly the problem I have with keeping lady bugs out of my house seems like it might actually be to my advantage for once. "Ok girls, you can stay but you better be on constant patrol!" The info you posted on exhaust fans and filters has been most helpful, thank you. I think the hardest part is going to be screwing up my courage to cut the hole in the ceiling and into the attic so I can patch in to the existing duct.
