Although winter temperatures are low, it doesn't prevent early seedling raising in greenhouses, allowing users to seize the opportunity of early spring vegetable harvests. Below, we'll briefly discuss some points to note when using Hydroponic Greenhouse seedling raising in cold weather.
I. Variety
Effective crops Greenhouse have many different varieties. Choosing the right variety is beneficial for seedling raising. For example, when raising seedlings in cold weather, choose varieties that are cold-resistant, don't require strong light, and have good resistance to cold air. This will reduce the impact of cold air.
II. Soil
Greenhouse have relatively high soil requirements at this time of year. Because the seeds are small, they need loose, fertile soil for better growth. Therefore, most Greenhouse are raised in specialized nutrient soil, which provides ample nutrients to better meet the needs of seedling growth. If you're preparing your own soil, you can use well-rotted farmyard manure and add some compound fertilizer.
III. Seed Treatment
Before planting Hydroponic Greenhouse seeds, soak them in warm water to ensure they are fully hydrated, promoting faster germination. Additionally, soak the seeds briefly in a chemical solution to protect them from soil-borne diseases before planting. After soaking, place the seeds in a temperature-controlled environment to germinate. The optimal germination temperature varies depending on the crop. Most seeds are ready when they show signs of sprouting; it's not necessary to wait for all seeds to fully germinate.
IV. Management
Pay close attention to the sowing time. This is determined by calculating the transplanting time based on the plant's characteristics and working backwards from it, primarily considering the ambient temperature.
Before sowing, ensure the soil is thoroughly watered to promote rapid seedling growth. You can also cover the seedlings with a thin film, removing it after emergence. Seedling management mainly involves temperature and humidity control. Before transplanting, slightly lower the temperature to allow the seedlings to gradually adapt to the new environment.
