Heat generation HPS 250 Vs. HPS 400

What is the difference in heat generated by a hps 400 and an hps 250?

I mean, in the same grow room, under the same ventilation conditions, how many extra degrees of temperature will be generated upgrading from a 250 to a 400?


Peace

Depends on the size and ventilation of the box you are talking about. But in general. There will not be a great difference in temperature between the two.
