I have been looking for the same, but from what I have found every breeder selling "Strawberry Cough" in seed form has a version where a female SC clone has been crossed with a male of another strain. So as far as I can tell, there are no F1 pure Strawberry Cough seeds. MotaRebel has several Strawberry-based strains and the lung candy #1 appears to be from a good gene pool because its a SC X Strawberry Diesel (SC X NYC Diesel), so a SC backcross with SC phenos and NYC Diesel phenos. Maybe if you got a SC pheno from a pack it would be close.
Then I see that Kushman has a dispensary "Buds and Roses Collective" in Studio City, CA and they are supposed to have the original in clone form there. Not sure how you could get it. Or why they just cant use colloidal silver and make S1 feminized seeds from the clones. I assume if it could have been done it would have been done by someone else already.
Kushman also said in a YouTube video he got the original SC as a clone from someone who asked him to check their garden and then gave him the clone as a gift. So Kyle said he wasn't impressed and was considering throwing the clone away, but it was in a paper bag and when he got home he opened the bag and smelled the strawberries so he grew it out. I wonder then why didnt he go back and get get males and produce seed once he realized how different it was? And the greater question is why doesn't the original breeder get credit for it as Kushman didnt breed it at all, but was just gifted a clone of it from someone else. I can understand if someone didn't want to be identified for various reasons, but at least they could be given credit for developing the strain, Kyle didn't, but sure seems to be getting all the credit for it. Just my opinion. Kyle?
