How often to water cuttings in pure Perlite?
How often do you water cuttings rooting in pure Perlite with a humidity bag? Perlite is not like other potting mixes where you can poke in a finger and feel the dampness. It's a closed system (rooting cup and bag), so theoretically, moisture should not be lost. However, if some cuttings take 4-6 weeks to root, I wonder if careful watering to re-wet the Perlite should be done?
