If you want a yes, then yes, you could grow weed in that thing.

But in all honesty, no, it would be a terrible waste of time and money to try and grow weed in that thing. Its just too small. You wouldn't yield anything. And it doesn't say anything about being able to adjust the timing of the lights, just that the lights turn on and off automatically. You need to be able to set the lights on 12/12 to flower. Spend the 150 bucks and get you some decent lights and some soil, and grow a shit ton more.
