Mostly just make sure they are fed well so when they start to stretch they are good and healthy.

I have seen heat sheilds or heat blockers, something like that for 1000watt bulbs. looks like a piece of iron that mounts under the bulb and partialy blocks the heat from the tube in the bulb. another possible way would be an extra sheet of glass with a small air gap between the two. or an ac unit in the side of the tent. try makeing the airflow go in different directions too, it can make a big difference. If you are blowing hot air downward by swirling it around it can make it hotter instead of cooler. dont know what will work for sure, just have to try stuff till it works. wish I had a better answer for you. let me know how it goes.
