Well your not wrong, an $80 light isn’t the same as a $300 light. Not even close. If your trying to flower a 4x4 tent $300 might not be enough. I see a lot of growers using Mars hydro lights, their reasonably cheap. But to cover 4x4 foot print in flower is probably gonna run $500+. Dont cheap out on lights, you’ll be glad you didn’t. Good luck
