the plant will be ok for 15 day what do you think?????
500 watts of fluorescent! That's a lot. If it's the right color (~2700-3000K) it'd probably be OK as long as the timing stays the same. Except, fluorescents need to be closer to the plant than HPS. (Will the plant grow into the light in 10 days?)

What kind of 250W fluoro is it? 500 watts of fluorescent puts out heat, too...
