On average, whats the most i could expect under a 1000watts. I am really trying to figure out if I want to grow on a 600 or a 1000. The equipment I am getting is the phantom ballast 1000 watt. But I am trying to figure out if its a big increase.
If you are getting the 1000 watt ballast, use a 1000 watt bulb. Don't stick a 600 watt bulb in there, even if you hace it set at 50%.
What u growing in? A room ar a tent? it all depend on your budget,growing area, and ur ventilation...a 1000W light will produce a lil more heat whiich will increase yout temerature in ur tent/growing area. plus the yiels would be a bit heavier with the 1000W but a 600W should get u some Good Buds 2. It all also depend on your growing technique/methods which will give u moe or less bud depending on how u care for them. Overall if u can afford it, i would go with the 1000W setup...
To many variables to even begin to answer that question. Try doing some research on GC. That's what it's here for
Watts is a unit of power (heat). So a 600w light will output ~60% of the heat that a 1000w will. Might be something to consider.
