I have been doing quite a bit of reading on lights. It is my understanding that the 400watt HPS light I have isn't nearly as useful during the vegetative stage as in the flowering stage. My understanding is that the HPS is lacking in the blue spectrum. I have recently purchased a couple of cheap clamp type reflector lights and 100W CFL's for germination. I'm going to have two 100W CFL bulbs in each fixture. My question is... Should I: Germinate under the CFLs and then change to the HPS for the vegetative and flowering stages. or Would it be beneficial to germinate under the CFLs, then use both the CFLs and the HPS for vegetative, and then use only the HPS for flowering?
