Ok guys, i am about to deflask my (mouldy ) catt seedlings. I have everything i need-

condies crystals (KMnO4) for a fungicide,
heatpad (because it is still cool here),
a nice large seed tray,
and the medium.

I just want to know if anyone here has had success using Coconut/coir fibre with seedlings? I thought it would be very similar to sphagnum moss, plus, coir apparently is naturally high in potassium and sodium (which i will need to condition with some gypsum and dolomite).

What are your thoughts?
