Mini-greenhouses made from inexpensive and widely available materials like plastic pots, bottles, and bags can be used to efficiently grow seedlings with minimal water and fertilizer. These seedlings can then be transplanted into gardens or fields, improving survival rates over traditional practices. Producing seedlings in mini-greenhouses is a good first step for combating desertification and issues with drought and poor soil as it maximizes seedling production while minimizing water and fertilizer use.
