I saw this, and the science nerd decided to find out. I have some Blue Dream that I harvested in May, spent 5 weeks drying/curing then placed in a freezer until I need it. This specific plant I had to pull 5 days before I planned along with a Gorilla Glue due to nannars. I made a video of them at the time to send to a friend for a laugh. In the video I pull a few off and show they are slammed full of pollen (at least the Blue Dream ones). However, I have only found 3 ripe seeds, lots of hard, white knots and tons of pistols obviously starting their conversion into what will become the tap root. Exactly what you would expect from a small banana pollination that was stopped in time--lots of "not seeds" and very few fully ripe seeds with normally dispersed stages in between.
I saw this post cause I had 2 fully-ripe, well-developed seeds come from a Jamaican strawberry kush plant I harvested 10 days ago. While trimming, they fell out and bounced on in the tray. But there is no sign of any other seeds in any other level of development, nor is there a nanner located behind the seed, nor any other signs of any pollen source. Moreover, the rest of the plant nor the other 2 plants I harvested had any signs of seeds in any stage of development. These 2 seeds pollen source is a mystery. I did have some males and early-flower herms about 7-8 weeks ago. I grew my first plant in 96, I know what a male looks like loooooooong before pollen sacks appear. So, that cant be the source. The only thing I can figure is---I packed a bowel while working with that specific cola for what ever reason, the dry plant I crushed with my fingers left either some Blue Dream or Gorilla Glue fem pollen made its way to that flower.
So, to find out for sure, I took a few hours last night with tweezers, flowers and plastic bags. I needed to remove some branches whose flowers are not receiving enough light but instead, I took blue dream and gorilla glue bannas, placed in different plastic bags, then placed the bags over an entire branch. Then, zip tied the bottom of the bag to prevent cross-contamination.
I'm testing 2 pollen sources on 3 different strains that are 6 weeks 3 days since flip. I will publish the results.
