I'm just in the process of finishing my first reversal with an auto. I had sac's after 3 weeks but it took 2+ more for any of them to contain pollen. It wasn't like the vid's I've seen where guys can shake the branch and a cloud of yellow stuff fills the air. It's more like I had to manually extract each sack and it was only about 20% of them had any pollen. You can see the pollen fall when you twist the sack between your thumb and finger. I self pollinated some of the lower branches, hopefully I can keep the plant alive long enough for them to be viable. I can see the seeds half way out of the calyx now, they are very green still. It's almost like they have an outer skin maybe ?
how strong is the CS you are using and how many times a day do you spray ? I stopped spraying mine when I saw them start to open up. But definitely no pollen spilling out. I had to hunt for it !
