Inyan Posted February 16, 2018 I know many of you have noticed that a stock cacti can alter the phenotype of a cacti scion. To that end, I would like to start a thread for anyone who has grown a specimen on multiple types of stock or even on a stock and then on its own roots to showcase how the stock can change the phenotype of a scion. I've also noticed that growing a specimen on the same species, but different cultivar can alter the phenotype of a scion. I will start this off with this specimen. Please share your results as well if you wish. If sufficient interest is shown I may show more pictures as well. Both are the same cultivar, but grown on different types of stock. 2 Share this post Link to post Share on other sites
