You need a couple more of those anyways. For what your trying to do you should germinate more than your going to use (say 10) and than sex them. You only want the best females out of these. You'll want all the lights you can afford of that wattage close as you can to all your plants. Use 3 gallons pots or even milk jugs if you have to. Just remember 3 gallons is the least weed needs. But can and have grown in a 1 gallon. Your personal preference for the health of your plants will overcome money issues and you'll gather more and more things you'll need in the future. As soon as you know they are female (research if you don't know via google) your going to want to cut the lights back to a strict 12/12 on/off. I believe it might take a little longer than say it would me till harvest. So you might consider raising the light quality and providing basic nutes at half strength every other time you water ( with a good drench inbetween).
