I am wetting my seeds tomorrow and my veg will be 24 hour 400w T5 for now. I need heat in my grow room, so rather than use a heater in the dark period I am going with 24 hour lighting. I will switch to 600w MH for first 10 days of flower and then 600w HPS for all but last 2 weeks of flower. Last 2 weeks of flower will be 600w MH with no glass in the hood.
And yes, it is a good read.
