How much light intensity?

How much light intensity should I be using. It’s 5 days old from sprout? I currently have the light set to about 45 watts and it’s about 12 inches above the tallest

Seedlings do not require much light but if you are looking for specific wattage to run, then @dbrn32 would be the guy to ask.

My T5 4000k seedling and clone light is 17 Watts. So you can probably lower your wattage or raise your light. Veg in general doesn’t require much light, but flowering is where it really counts.

He will answer your question once he sees my tag.
