Clones going moldy in propergator

[Whitehotdog]

Hi guys
Been having problems with my cuttings going mouldy in propergator then die
Done cuttings before with same set up with no issues
Set up is small propergator with vent onTop .
Rapid root blocks
Spraying daily with ph correct water
Under a small energy saver light bulb
24/7
In a small tent but with good air flow
Tried with vent closed and vent open
Any ideas

Add H₂O₂ to the water. Stop using rapid rooters if they're like the things I got a while back that came with white mold spots on them. Increase oxygenation at the root zone area (bottom of the stem, whatever you call it before it grows roots).

If all else fails, stick them in glasses of water and park on kitchen windowsill, it still works as well for rooting cuttings as when your grandmother (and her grandmother) did it.
