Well this is my first outdoor grow and she had a big head start before planting outside. I started out with the intention to Flower her by herself indoor, but decided to put her outside and see how big she can get under the sun. She was upsized from a 5 Gall fabric pot to a 15 Gall fabric pot a week ago. She is doing well despite a few nights of just 6 deg celsius. I have to move her late afternoon to benefit with more sunlight. She is heavy but slides pretty good on the deck. Started supporting some stems with green soft wire ties as she is getting wide. Tomato cage is a good addition. Not sure if I have to do any topping, time will tell.
Those are definetley pistels. Mine here in london ontario have just started flowering too. By the looks of things you are safe to start counting flowering days. Peace
Wow , Your going to have to take that fence down for more room. lol been dropping to 12c a night for a few nights in your area. October your Pumpkins should be ripe. ๐
