I take a few different things away from this....One is we all have to realize how important the first 15 or so days after pollination are. Most of us get excited after day 20 and start to really treat the plant properly when, in reality our fate is already sealed. We have to make sure we look after every single detail during this cell division phase (heating, cooling, water, fert, shade, misting, etc) in order to maximize our potential. In regards to terminating all the growth before pollination, I realize my plants are likely too small to grow something bigger than I usually do (1300 pounds or so). They are usually about 300 sq ft at pollination time and I grow them out to 600 sq ft. I might not be able to grow a bigger one by terminating growth before pollination, but perhaps I can still grow 1300 pounders and be done vine burying by July 1st.
Maybe for me I'm better to grow the plant a bit bigger and pollinate a week or two later. I've always aimed for an early pollination, but maybe a bigger plant that is terminated during the cell division phase will be better than a pollination 10 days earlier. There's lots of different ways to implement this new information, we just need to decide what to do. Do I try to grow a 1300 pounder on a 300 sqft plant? Do I wait a week or two for a bigger plant, then terminate the growth as soon as I see the female show up and hopefully get to that next level? I'll likely try both, but I will for sure be paying more attention to the call division phase of the pumpkin. Ideally a heated greenhouse with a real early start so I could have a 600 sq ft plant by June 15 is the way to go, but definitely not in the cards for me at this time.
