Still Learning
what? 10 years ago CMH came by way of a 400w bulb that was sparked by a standard 400w MH ballast or was it 400w HPS ballast. I still have that set up on the shelf.Which 400's?
The Agro has a bit different spectrum. Cool.
I still have 5 of the Retro White 400's that are great.
EDIT: sorry Sub, I read you post sideways and came to the same conclusion
