 I read in Langevin's book and Wayne Hackney's pamphlet on AG growing ,
 very reasonable approaches to watering an AG yet when I read of some of
 the biggest pumpkins produced I see extreme watering regimes (Chris
 Anderson for instance). What am I to think of this in trying to do the
 best I can? What road do I take? What gains can one expect from pushing
 the edge of the watering envelope and what risks does that intail. What
 exactly would an extreme approach look like in technical terms? Those
 out there who are pushing this side of growing let us know what you are
 doing and why you are doing it?

Doo,
   Most of the people doing heavy watering are doing it for temperature
control. The heavy waterers use very small spray nozzles so they are watering
for long periods without drowning the plants. You must have sandy or very well
aerated soil. Pumpkins are very sensitive to a water saturated  root
zone.....it will kill the roots in a short period of time. People in the
Northern U.S. or Canada where 90 and 100 degree temps are rare, would not have
to water like this. My spray nozzles are .3 gpm and cover a 25 foot circle.
With a nozzle like this, I would have to spray 12 hours to put on an inch of
water. If you water to the point where the water is starting to take up the
air spaces in the soil, the plant will suffer.
