When To Remove The Jiffy Greenhouse’S Cover?

Starting seeds in a Jiffy Professional Greenhouse involves pouring off excess water, pulling netting open on top of pellets, sowing seeds or plant cuttings, and covering lightly and firming down gently. The greenhouse is designed with peat disks in a plastic tray with a clear dome lid, and is under grow lights in the utility room. The air temperature with the lid on holds around 25C, while the tent temperature is around 18-20C.

The lid provides humidity and can be removed anytime, but it is important to ensure soil stays moist for germination and mist the plants. If new seedlings get leggy, the light should be turned off. Once seeds have started to sprout, adjust the lid slightly and remove it once all seeds are sprouted and growing.

To use a Jiffy peat pellet greenhouse, follow these steps:

1. Prop the lid open when first seeds sprout, then remove it completely when all seeds have germinated. Add water to the tray when the pellets have sprouted.

2. Remove the greenhouse dome and apply plant markers where necessary. Place the lids off once the plant starts growing up as long as it doesn’t get cold by a window and maintains warmth.

3. Turn the cover slightly for air circulation during sprouting. Remove the cover when seeds have sprouted and gradually expose them to sunlight.

4. When some seedlings sprout and stick up, lift the lid to let in fresh air.

In summary, starting seeds in a Jiffy professional greenhouse requires careful planning, proper preparation, and proper use of the greenhouse.
