How big of plant? Or better yet, how big is your space?

Assuming you’re looking for the best possible outcome? The recommended par levels for flowering plants is usually between 600 and 800 umols. Here is a reference point

Obviously you can use less, it just reflects in your yields. A couple of things to help with cfl grows, are to use cold white bulbs for veg and warm white for flower. Also, if you can get them horizontal with a reflector over the top will help a lot.

It’s hard not to admire the lighting knowledge. Is that all just experience or do you have a background in electrical?

I definitely have that. Not like a residential electrician though. More automated systems.

I just need to know what wattage and which exact light to buy? Would two 300 watt (85 watt equivalent ) daylight cfl bulbs work?

per square foot of canopy during flower :wink: average is relative term always base lighting need on size of space 4x4=16 ft so 16x50w=800w or 1000w HID 2 400w HID 1 600w HID min
LED’s can vary in quality but still want min of 35w per sqft true watts with most commercially available LED’s Keep in mind quality counts :wink: A high quality LED of equal true wattage to the 50w min rule will get you best yield more PAR/W than HID
