LONG PERIODS OF TIME WITHOUT RUNNING AIR THROUGH IT? THEY ARE AIR COOLED HOODS WITH GLASS COVERS..HOLES ON EACH END..SAFE FOR BULB TO RUN WITHOUT AIRFLOW???
Yup, I'll start a journal and that aspect will be covered as well as everything else, I'll be running the light a full 72 hours starting on tuesday, so I'll start my journal after I figure out my temp situation....
i'd be more worried about power spikes and outtages. i actually run two surge protectors before my ballast just to be sure, since my power tends to go out often in the winter months.
Of course you could run anything in your room as long as you keep the temp down. Using the right fan and an air conditioner you should be fine. My friend just finished using 2 kwatts in one room and they wern't air cooled hoods. Just used an air conditioner to keeps he temps down. I do love a/c hoods. Be sure to have a thermometer!
Like everyone else is saying, as long as you have some kind decent ventilation in your grow space you should be good. What are the dimensions and how many plants are you planning to put under it?
I have a 1000 watt hps that is the same way glass and the holes on the ends for ducts. I have NEVER had a fan going through it for like 2 years. I should get one but have never had a problem with too much heat
I am currently running a 1000 watt hps in a closet, heat is a HUGE issue with me. Mainly because i have not istablished a defninate air plan. My constant temp is around 86 and my humidity is around 18%. A light of that wattage produces alot of heat. and i had to invest and learn trial and error about venting my fan and the temperature. In the confined space, the heat build up is alot.
Im just warning you about whats goin down with my situation.
