Wow, that's a bit of material to make the concentrate. I can't really answer your question, it is completely out of my realm of knowledge. I think with the right strains you can get some good yields. As far as I know the reason for curing is to improve the quality of smoke/vape. I know my wife prefers her meds cured for at least a month. She says it taste better and is smoother to vape. She has never said that it was more potent. Of course I don't partake so I can't speak from personal experience.
If you are talking about different strains giving higher rso yield, you're right about that.I was lucky enough to get Candy Crush and that yielded 4.25 grams per ounce,it looked like it was covered in sugar; it was stellar. That is why I picked the strains I did, they all seem to be higher quality and pics on this forum seem to show them looking the same as the Candy Crush I bought. I know that it comes down to growing it correctly, but still, the fact that they can come out that way is great. My strains are West Coast OG, Green Crack, Girl Scout Cookies, and Crystal Meth from fast bud. I hope to grow at least one of the standards as well as the ones I have seen here and yield 4.5 grams of oil per ounce. Thanks for all of your help!
