Hi
I have 1000w grow light, I also have a light gauge that goes from 0-1000 I’ve read that 500 is a good intensity is that true.

Sounds like a great light setup for your seedlings! I would definitely stick to the recommendations on the package and keep them between 28-36″.

In order to grow strong, healthy seedlings, it’s super important to provide the proper lighting for them right from the start.
