This shouldn't be happening but this girl is in flower. The girl is a clone from a femenized photoperiod plant so it shouldn't be flowering for another couple of months.
@MrMunchies, I also love pumpkin, in autumn I use it to make gnocchi :) Last year something similar happened to me, a plant that we didn't know what it was sprouted, in the end it was a cherry tomato plant. I like surprises that you can eat 😂
@HirdoWeirdo, I also love zucchini flowers but these are butternut pumpkin. I hate pumpkin but these plants grew from seeds in the compost. My wife and I were wondering for months what they were, could have been squash, zucchini but turned out to be pumpkin. At least she will eat them.
