You need a 100k poti, 10k would limit you to 10% of the driver output at max....
growth is awesome for only 20w, BTW.
Also try to rise the temperatures inside your room to 25-30°C for max. photosynthesis. Low temps leads to less transpiration and this can lead into some nute deficits over the time.
Remember, a plant with only 500μMol/s at 30°C grows faster as a plant with 1500μMol/s at 20°C.
Assuming these lights have no lenses you can lower the heights to 45-60cm without getting bleaching to rise the ambient temperature. If this is not enough, reduce the air flow or use an additional heater.
