The mix was persistently drying out unevenly and watering unevenly, which was leading to watering woes, always leaving them underwatered or overwatered. Using straight Turface MVP and Sphagnum (50/50), ability to truly control moisture in an out-of-the-box environment is pretty tough. I was constantly using a syringe to shoot water into the bottom, middle or top of the cups. It was getting to the point where all of the drying and watering was impacting the roots, they were starting to look pretty sad in some places.
I could have probably avoided this if I would have religiously kept them in the box rather than moving to a window. Of the roots that were there, they looked good - most all of them - which is why I'm hoping and wondering if they'll bounce back. All of my cupped plants in Fafard3B-Perlite mix are doing great, and I've transferred some out recently into pots, and they're doing magnificent. Just these Turface/SM ones that I'm having issues with.
I still have a couple of spares of each, so .... maybe I'll get lucky and one of the Conadria will survive, plus I have one spare still in cup, and I have a couple spares of MBVS as well.... but I'm having a lot of the same watering problems with one or two of the spares (same Turface/SM mix)
