If you were expecting medicinal benefits from the strains you listed them I'm afraid you picked the wrong strains. Stitch has only gotten into creating medicinal strains in the last year and a half or so, starting with his White Sirius. Those strains, Mi5, RRF, Onyx, HBD, are some of his earliest creations and are more recreational strains. They are considered dwarf strains and normally grow in the 14 - 24" range. If they all smelled of hay, then I suspect you didn't dry and cure them properly. Mi5 has a fruity smell, RRF smells of diesel, Onyx doesn't have a strong aroma and HBD can either smell of blueberry or diesel, depending on the phenotype.
Off-topic, admittedly. Please do not hesitate to move to a more appropriate place, this was at the top of my screen on the right and gave me a question, haha.
Just so I'm clear, how do we determine medicinal vs rec? Sounds like possibly end yield judging from what I'm reading? I'm well medicated and not very good at reading, so as well as medicated i am confused, hha. Rich in CBD?
