That is a very good site, but it's a little generalized. For instance, hot sauce may be very salty (there's a thread showing some messed up seedlings and the guy used hot sauce). Also, the milky spore, how can it know to kill the right grubs?
It did not mention nicotine spray (that's what I've got steeping tonight, I'm gonna kill those little fuckers!). This MUST be used with extreme care and caution, though. In other words, do your research and don't let it soak into your skin or get into any waterways. Also, know that it'll kills pretty indiscriminately.
