Do you love gardening? Having a garden full of flowers and vegetables can bring pleasure, but it is even more pleasurable when you start with the seeds and prepare these plants' seedlings. Is it hard to grow the plants right from the seeds stage? As a beginner, you need to learn as much as you can before taking this step. When I first decided to start planting the seeds and seedlings, I did not have much idea. A friend told me to put the seedlings under light, and all I could ask him was, when do I put my seedlings under light, even though I did not know why the seedlings had to be put under the lights.
