oh another question i forgot to ask.. looking at the above lights i have bought, 1 300w red and 1 300w blue, to my understanding blue is better for veg with its 65000k and red for flowering with its 27000k right?

As I Plan to use autoflowering strain, I have some options:

1) use blue light for first 2 - 4 weeks, then the red one from there till harvest?
2) have them both full throttle until harvest?

I am leaning towards having both red and blue on 18/6 until they harvest as i guess two is better than one

What are your thoughts?
