I took the 2nd node clone stems (as
@Gee64 calls them) as cuts from the new Blueberry CBD plant.
Standard practice is to take them from a healthy mother, which this plant is, but the cuttings themselves are a bit faded out from being below the canopy, so I'll have to see how it goes.
I just uppotted the mother into its final 2G SIP to prep for flower in a couple of weeks so I'll probably leave it go mostly uncropped for a bit to see if I can get a few more cuttings before flip to be sure the plant continues on as i expect it will be my main workhorse going forward.
Also, I checked on the cuttings from the Hibiscus plant by floating them out of the perlite. No roots yet after 14 days, but all continue to look quite healthy.
One thing I don't like about the perlite is how messy it can be, but this process is similar to how the commercial propagation nurseries do it, except many of them use overhead misters on a more frequent timer and use beds of sand rather than perlite.
So, I'm going to try changing from perlite to sand on a future round and see how it goes. One thing about the perlite is its easier, and less intrusive, to check for roots than it would be in sand, but if I can get a high strike rate it probably won't be that much of an issue.
