Unfortunately, those lights are just not suitable for growing rewarding results.........they may be enough for a plant to survive, but certainly will not be enough for growing quality buds and no doubt lead to disappointing results.
You would be far better off buying quality grow lghts that will give you an enjoyable harvest in 3-4 months time.
Spending 3-4 months trying to grow a plant with unsuitable lighting would be a waste of time, effort and money in my opinion.
