I've been doing some research on the subject of CO2 enrichment of the
growing environment. Reasearch indicates that increasing the CO2 in a
growing environment can increase yields from 30-40%. One experiment
showed increases of 100%.
Unfortunately the equipment requirements and constraints are high,
requiring a closed cgreenhouse. This makes it impractical for some of
us who are not in a postion to provide significant cooling capabilities.
I came across a formula for CO2 enrichment that goes in the nutrient
tank at the following web site:
http://www.hydro-techn.com/GrowingGuide/HTML/carbonliq.htm
The formula is:
1 Tablespoon 35% H2O2
1 Tablespoon finely ground Lecithin
1 Tablespoon Blackstrap Molasses
Normal dose of Seaweed Extract
organic or chemical fertilizer
The web site has specific information on mixing sequence to assure
solubility. Since none of the ingredients is prohibitively expensive it
seems worth a try. The author states that the H2o2 dissapates within 24
hours, so it should be replenished daily. I'm not sure about the other
ingredients.

Damn! Did Ken Lott start this one too?

If the contaminants are predictably known then remediation
techniques, such as activated carbon, ion exchange or
reverse osmosis, can make the rainwater supply OK (as long
as a conservative maintenence schedule is followed). If the
contaminants are variable the remediation technique selected
may be ineffective or even destroyed by the unanticipated
contaminant.
For determination of contaminants there are many inexpensive
government subsidized water testing programs available. I
would pursue their existence through the state ag
department, state ag universities outreach, health
departments, etc.
There are also quite affordable commercial test batteries
from mail order companys that charge a fraction of what
local commercial labs do for an amazing array of results.
The drawback with these is you must wait for weeks to get a
result back. Sometimes if you are willing to wait a local
lab will give you a price break.
