So long as there not in direct light they will be fine, seeds germinate better when it's dark, but as long as you have them planted good it should be fine.

1 400w is enough for seedlings.

2-2.5' away from seedlings is good for sprouts.

You only "need" 1 400. More is a waste, but in reference to your question... No, 800watts 2.5feet away will not burn your plants. It's just unnecessary.

Nope the blue spec is more suited for foliage growth. Red spec is for flower.

mh = blue hps = red

But you can use it.. It won't "hurt" them
