Preservation of Blackberry Fire Cookie

What to do with all these vendor samples and giveaways? use them up before they go bad. I'm a bit of a sample whore when it comes to this stuff always looking for the bigger better bud maker. This grow is another unique one as I will be attempting to preserve the Strain Blackberry Fire Cookies from Purple caper seeds. I got this from the 2017 SoCal Cannabis Cup the guy gave me the last pack of these I think it was a cross they made with an existing Blackberry Fire strain and they crossed it with GSC the lineage is as follows Blackberry Kush x Fire Lady x GSC Regular seeds. I have looked on line and cannot find this particular strain anywhere I hope its worth saving "The Fire Lady is a famous Purple Caper original phenom that has a THC potency that typically does not test lower than the 25% so I anticipate a high THC percentage on BlackBerry Fire Cookies. now add GSC to the mix and I can only guess what will be. I'm hoping for at least 2 girls or more but out of 5 seeds we will see. one is all I need as I will be chemically treating the female to self pollinate S1, if I have 2 girls them a can pollenate the second one and should have feminized seeds and less chance of hermies as may be in the S1 batch. wish me luck GD. Addendum: Sprouts are in the nursery after 3 days in the wet towel hope all 5 take so I have better odds of getting a lady or two, really happy all 5 sprouted. I should have my answers in 6 weeks on the male female ratio, then the fun begins getting my co2 tanks certified and filled this week end. till next week don't share your bong or doobies stay safe. P.S. these sprouts were getting leggy so I had to pot them up an bury the stems for support I hop stumpy joe or Josephine will make it the only one to lay down from the long stretchy
