To any spider farmer SE7000 users...

For all Spider farmer lights it's 30cm pal. Good luck.

I'd turn light down and lower it down for first two weeks

That seems too close for that dim setting

I would raise your light since it is more then strong enough, best way to tell if you are at right strength and distance is by how plants respond. I have noticed the distance is slightly farther then they tell folks from personal use of a SE3000. When you hit the sweet spot for the light the plant leaves will grow perky outwards, and more erect or at attention. Each strain will be different slightly as they all are.
