LIP Reviewed by LIP on . 800watt Dual Spectrum Light Would a 800 watt dual spectrum light produce big buds. It is just 2-400watt lights that is why I am aasking the question. It will produce bigger buds than 600watts and small buds than 1000watts right. How many PLANTS WOULD ONE 800watt light cover. Rating: 5
