RE: water temp
Ethan,
It probably depends on how you are watering the plant. But 80 degree will
not hurt the plant. If it gets really hot in the summer, using well water
(colder) might actually help to cool the micro climate of the plant when it
gets too hot by applying to the ground through a soaker hose of some sort.
It's not good to put water over the foliage in the heat of the day because
it may scortch the plant. But I don't think that the temp of water (80-90)
that you guys are using is hot enough to hurt the plant. If it got over 100
degrees, I would find a way to cool it. Don't you guys have problems with
alge growing in your water tanks?
As far as shocking your garden with cold well water. I have a hard time
believing that this is possible, but this is my first year with giant
pumpkins. My regular garden in the past and most farmer's in my area that
irrigate their corn crops use cold well water as their source. But these
pumpkins may be more sensitive, I just don't have any experience or
agronomic knowledge on that subject.

Hello Melissa. Many growers use water storage tanks to water there plants.
In the summer these tanks can get to 80-90 degrees easy. I think this is a
common practice to use solar heated water. I believe cold tap water or well
water will only shock the plant and do more damage than good. What do you
think?
