Thanks, I think.
I hope you are not offended that I am scribbling on your Grow Journal. I am still learning and this stuff is confusing.
Your experience switching from CFL to HPS helps me understand. I will test if doubling the CFL can give hard nugs.
Not at all my friend, I've only been growing my own for a year now so I'm still trying to absorb all this info and put it to good use with my grows. With regards to hps vs cfl from what I've learnt is that hps gives of more lumens so I'm guessing if you could equal the same lumens you would achieve the same results as a hps.
