From a fellow grower: Is this light sufficient as germinated seeds not growing- VIVOSUN VS2000
The light is sufficient to flower one plant.
A light won’t be the reason seeds aren’t growing. The most common cause of seedling failure is overwatering.
The VS lights are adequate veg lights. I wouldn’t rely on them to take you through flower. As an owner of 2x VS1000s, they’re fine but you can do a whole lot better for the $$ by looking into Horticulture Lighting Group fixtures.
