Excellent Question
The amount of light needed (at any given time) is relative to the amount of space allotted to the grow AND the overall size of the plants. 1-4 leaf sets can only process so much light. More than they need is wasted and can in fact burn the leaves, as well as overheat the top 1-4 inches of the surface of the soil, slowing growth.
If using 1000 watt to veg, you better have it far enough away so that the net effect to the young plants is less than 400 watts, and 200 watts even better. Once you hit 4+ leaf sets you an slowly lower the 1K, but be careful.
I will be using a Quantum T 5 Bad Boy (8 bulbs at 54 watts each = ~400 watts, to finish a lone surviving plant I started under a UFO 90 (LED).
I bought 8 each 2900 and 6500 bulbs. Instead of replacing all 6500s with 2900s, I can slowly introduce the 2900s. This allows me to mimic the light change from Autumn to Fall. It should be interesting.
