Extreme Gardener (site member), also in Vermont, is a big fan too (perhaps the same person?). Anyhow, I am growing a selection of melon this year, including hopefully Piel de Sapo - I'll have to check to see how it's doing. My husband is from Spain which was my part of my initial interest.
I had a quantity of 9 year old Piel de Sapo (and also Valencia) seed, which I sowed very thickly a few days ago in hopes of getting a few to germinate. Fingers crossed!
I have found a med of 15,86°C during the period between the 1st may and 30th october i have calculate 15,86°Cx180 days i have found 2854,8GDD for a base of 0°C For a base i have found 1054,8 GDD 10°C 1898,64GDD 50°F
For the melon may and october are a med under 15,5°C 60°F.
During the period of the 1st june at the 30 Septemper, i have found 261 GDD 15,5°C A mean of 17,675°C during this period. But i think that the temperature is not the alone factor. Th intensity of the light, the humidity play on the grow.
Its a false value but i have take a years estimate at the normal without cold wave and heatwave, in reality, i think that its more hot.
the extremes here have been a challenge to work around, but so far we are managing as long as i can keep the gardens watered during the dry spells. i have to change my behaviors though to cope (working outside more in the morning than i would normally do - i am not a morning person).
