Hi Gerald, How far are you from starting to plant? Started here last week.

Here, it seems the exhaust gas salesmen have changed their story a bit. No longer promoting the benifits of N, but they have now switched their pitch to that of the extra special carbon that is in the exhaust gas, does something mysterious to the bacteria in the soil and makes super nutrients. I wonder?

This deal has a LOT of similarities to those who promote homeopathic medicine cures. Google up Homeopathy once, and do some reading. See if you agree, or at least get a good chuckle.
