I did the main stem on the Dark Devil as it keeps wanting to stretch. The stem is still very pliable so was easy to just pull it over and the pins holding it down in place. I'm thinking that the silica that is in megacrop helps with that. Last grow with AN they were very hard and woody so wasn't as easy as this time.
Same strains with the MC and AN comparison?
I know silica can make stems stronger and bigger. So stronger should mean it can withstand more force from a bend via a tie down or a pin. But I would have thought silica would make a stem stiffer, not more flexible.
Have you got a good close-up picture of a pin on the main stem?
