Hello all, I have planted some of my Griffinias (G.liboniana) in pure spagnhum moss and they grow extremely well in this material indoors, I checked the roots a while ago and they were in exellent condition. My other Griffinias are planted in spagnhum moss mixed with perlite, a special soil, and South American lava and moss and they grow very well too. No coir at all I'm going to throw it away and never use it again, but as I wrote earlier It might differ if it's used outside and not indoors? Happy new year to all of you! Tomas
