Cool... I'll keep that in mind. Thanks.
From Univ. of Minn Agg Extension. Article is geared towards germination but some applies in regards to managing threat of damping off for cuttings. And as you probably aren't/shouldn't run cuttings under intense or hot lights, there's probably not much need to insulate heavily if they are near comfortable room temperature. But again, your environment/conditions may be different from mine:
Disease is particularly severe when seeds are planted in soils that are too cool for optimal germination or when weather turns cool and wet after planting resulting in slow germination and growth.
The damping off pathogens thrive in cool wet conditions. And any condition that slows plant growth will increase damping off.
Preventing and managing the disease
- Use a heating pad under trays to warm soil to 70-75°F for indoor plant production.
- Use clean warm (68 – 77 F) water to water young seedlings. Cool water (50 F) slows plant growth and increases the opportunity for infection.
Damping off is a disease of seedlings Seedlings infected by damping off rarely survive to produce a vigorous plant. Quite often a large section or an entire tray of seedlings is killed.
