Top 10 Plants to Start Indoors from Seed
Growing seeds indoors is a great way to have more control
over the growing environment, extend the growing season and save money. When choosing plants to start from seed indoors, it's important to consider factors such as the plant's growth habits, DLI requirements, temperature requirements and how long the plant takes to mature. DLI or Daily Light Integral refers to the number of photons received by a plant that provide photosynthetic activation. If you need help calculating your plant's DLI, please check out Active Grow’s DLI Calculator. With the right care and attention, starting plants from seed indoors can be a rewarding and productive experience.
