Pure Harvest - I appreciate the offer on the excel file. I shoot you my email in a PM in just a moment. I have heard of the book you are referring to as well. Everyone seems to speak highly of it.
I also checked out your forum threads that you mentioned. Obviously you know what your doing.
Ill admit that I was pretty much lost. I understand the very basics when it comes to PPM and EC, etc. but that is it. Clearly you have a fine tuned program for your plants.
Bower - Nothing wrong with being thrifty. The bags in white help to keep the soil and roots a bit cooler in the summer heat. For those folks up North, its no big deal. For us in the South, I can't see black bags working out too well. Unless you just stick the water hose in the bag and let it run while the sun is out.
