Propagation covers in November: When should the lid come off?
Condensation alone cannot tell you when to water. Check growing conditions, plant stage and the right G24 cover at your November window.

At a window in November, warm room air meets cool glass. If you are already caring for a suitable batch of seeds or cuttings under a clear cover, a misted lid will be a familiar sight. Those droplets are a reason to check the plants. On their own, they tell you neither whether watering is needed nor whether the plants should stay covered.
Look inside before taking action
Lift the lightweight cover gently by its edges and place it safely aside. Check the plants and growing medium separately: Have seedlings appeared? Are leaves touching the lid? Is the medium still moist? Condensation on the cover cannot answer these questions. Do not automatically water again just because the lid happens to look clear.
Seedlings and cuttings need different transitions
For ordinary seedling propagation, remove the germination cover once seedlings appear. Follow the instructions for the species you have sown. A persistently humid, enclosed environment with little air movement can encourage disease.
Unrooted leafy cuttings, however, may need high humidity. Ventilation is still part of their care. Once they have rooted, increase ventilation gradually to help the plants adjust to lower humidity. One fixed ventilation period for every species and stage would be misleading. Succulent cuttings also need their own propagation guidance.
The actual window position matters
Choose a level, stable, water-resistant surface. Keep foliage from pressing against the cover or cold window glass. Check the temperature where the plants are growing; direct sunshine can cause excessive heat under a cover. When airing the room, keep tender young plants out of cold draughts.
The G24 cover has no adjustable controls to open. Lift or remove it gently to inspect the plants and ventilate as needed. Check the available height before plants reach the lid. Do not rush to cut openings into the thin material: first establish whether the cover is still needed at this stage at all.
Finish with a clean check
Remove plant debris, clean the cover gently with water and check for cracks. Let it dry completely before storage and do not place weight on it. If it is still needed, fit it carefully and continue monitoring the plants. If it is no longer needed, store it clean: the next stage of propagation can begin without a lid.
