I am consider a very small 2-4 plant grow. I have ruled out metal hylide and high pressure sodium. I am thinking of flourecents only this time aroung for veg and flowering. My question what is the tru minimum I want to use to produce a decent yield? I have one nice suspendable flourecent fixture that hold two 40 watt T12 type bulbs 80watts total. I was told this was sufficeint for vegging if it's lowered about 4"-6" above seedlings. However I know I will need to addmore for flowering? How much and what would you suggest. Would another identical fixture and 160watts of cool white be sufficent. Or do I need to add other types of bulbs emmiting different color spectrums. Any and all advice would be appreciated.
