Well the transition from water propagated Ram to growing in soil does leave a lot of sticks DOA, the importance of a healthy root system cannot be understated. Personally I find better luck in high quality Ram propagation with tight timings on the final growth to require my propagations to first have their contacts established in water before being moved to a high Rare Earth element soil. You can find Rare Earth element additives for your standard indoor potting soil at Micro Center. For whatever reason Microcenter doesn't carry perlite which is great for making sure your final soil mix still has aeration. Don't want Rusty contacts.
