I just bought a sylvania 250 wat Metal Halide light. I have a medium sized fish tank i'm growing in, will the light be enough? And how far am I going to need to keep the light away? Thanks

Can u go into detail on the fish tank a bit more mate. Actual dimensions?
Is it gonna work as a grow box? Do u habe a ventilation plan?
Are the walls mylard up etc etc?
The 250w can be anything from 6inches to 14 inches away. Closer the better.

OKay the tanks dimensions are 1.8 feet (length), 1 foot(height), and 10 inches (width)
Now with the heat, what if I just put a fan directly above the tank blowing into it? PLus the tank is really close to my ac vent.

if u have central airconditioning without* venting the hot air out around the room it will get to about 85-90 degrees. if u vent the hot air from the light u can get to the plant about 3 inches to the plant with out burning your hand. u will get good results from a 250 if the plant is a high yielder.
* keep the light a foot=12 inches from the plant. the plant can suffer from humidty ( wilting) if there no fresh air going into the the fish tank.

So a fan blowing on the plants won't be enough fresh air?

Well the plants are closer to the top. I have them on a stand. They're like 6-7 inches off the ground.
