One who orders hundreds or thousands of seeds from 'seed banks' does not intend to grow 5 or 10 plants for personal use. I have quite a number of non-coerced (actually some guys were rather proud of their indoor grows) post-arrest statements which say they were harvesting $250,000 three times a year from an area the size of a single car garage or less. Using new technology, we were getting exceptionally good at finding these without any help from informants.
As for guys who sell grow lights and hydroponics, I did the undercover work on the largest supplier of such hardware in the US, taping his instructions on how to grow the best stuff, and then charging him with aiding and abetting. He folded up, pled guilty and gave me the probable cause for over 3,000 search warrants in 30+ states. I asked for and received the services of every state police trooper in Indiana, the national guard, and dozens of out of state DEA agents to do 350 search warrants in one morning starting at 4 AM. Only three, less than 1%, did not produce a seizure and arrest. When I say I wouldn't walk around the corner for 5 lbs of pot, I'm not agreeing with you that it's unimportant, just that I had bigger fish to fry, and a man has to have his priorities straight.

THAT's why I said I was LMAO, earlier, not that such stuff was beneath me. Agents aren't special, they're just ordinary people put in extrodinary circumstances.
