no heat problems!

[POLARIS01]

i was planing on running a 250 mh in a 2x4x8h veg room and 2 400 hps in a 8x8x8 flower room. i took the 400w an put it in the 2x4 room to see the temps. well guess what the temp went from 75 to 81-82 with no exhuast or intake. here is the deal, the light has been on for 2 hours and its 75 outside. what do you think? will the temps go up every hour? should i run the 250mh or run a 400mh? i am going to veg 20 plants in 1gal pots for 8 weeks.

Even if the temps don't get above a harmful level, your plants will still suffer, since they need fresh, co2-enriched air, which should be constantly replaced. Also, humidity will be an issue when you get all the plants in.

Figure out good airflow, and growing is easy and productive. Without it, there are lots of potential problems awaiting you.
