Have you found out the wattage's yet?
You said 2
led, but you didn't say what type.... You also said 16 sq ft, so I'm assuming it's a 4 foot by 4 foot space, and the only thing your growing under artificial light is one strawberry plant. So I'm guessing this is basically just an experiment since one strawberry plant isn't enough to get enough strawberry's from to even make one strawberry shortcake with.
P.S.
Will the hot house be using natural light?
