Other than some really sad looking seedlings, don't expect much out of that set up. How tall is the wardrobe you were going to use? You might be able to get away with one plant, but you would need to increase your light...especially with growing Sativa. Northern Lights is a fairly robust strain, and is fairly resilient. But until you boost the lighting situation A LOT, don't expect much. Think about it this way. You have a dog. It has the potential to be a great runner, super healthy, very strong, and able to work hard. But you don't feed it enough. You give it a couple of Kibbles of shit food. And then you wonder why it doesn't live up to it's potential. Lighting is super important for pot. Yes, it grows like a weed even in most austere conditions, but if you don't give it even the bare minimum of what it needs, you won't get anywhere. There's lots of resources out there that can help you with your grow. From room set ups, lighting specifications, nutrients, humidity, temperature. Try finding either the "Marijuana Grow Bible", "Growing Elite Marijuana" or even Robert Bergman's free PDF download. Grow weed easy website (this one) has a TON of information in it...It literally takes you by the hand and guides you step by step. One last thing: Generally speaking, the MINIMUM watts/square foot is 50-75W. So, you're going to need A LOT more TRUE WATTAGE for even one plant in your wardrobe.
