I know with hps it makes a difference I literally use a bulb for one grow two max then replace them I feel anymore than that you definitely loose some light intensity I imagine with cmh it be the same a couple of grows then you will maybe notice a slight drop ?

I’ll keep checking the intensity after each grow. See how much it’s actually diminishing

Set up a test rig that you can leave in place.

Only got space for 1 tent. Wife would not be happy with me setting up another xD

I figured a measurement of ppfd after each grow would suffice for my needs

Try to set it up in the same place with all the same stuff around it, to minimize error.

Is it dimmed? That is a lot of light for a seedling. I keep them under t5 until they are five or six true nodes before moving them.

Yea typically start at 450w (adds the heat) and move up to 630w early flower.

The light is about 3/4ft away and they grow up into the higher intensity.

Shes doing good now!

NEVER dim CDM lights! It drastically shortens bulb life!

Remember that anything HID lighting can do, LED can do better.
