most likely.

my plants right now are in five gallon buckets and over 3ft tall off just a 400 watt hps so you might need more height unless your gonna lst it

If you only have 2' of grow space, that lamp will use up everybit of it. You have to figure out the heat and proximity to the plants. That lamp is prolly 6" minimum, your plant in a small pot is at least 1' so that leaves your light only a few inches away from the tops of your plants. Can you say BURN? Definately do what you can to get more height or its going to not work. Sorry
