Good vibes

Start 07/09 All seeds opened after 36 hours. I put them directly into cubes of rock wool, sunk about 5mm to 1cm, the next day the seeds came out of the cubes. Good vibrations to come. Day 3, I put them in 15x15cm pots, filled with "canna coco professional plus". I fed 4ml/l of rizotonic and 0.5ml/l of coco AB. Day 5, a seed died, it failed to open the hull sufficiently and rotted inside.
