Now their hatched, what next?

I have about 4 different watages of light bulbs handy to adjust heat requirements. I usually start with a 75 watt and reduce to a 60 and usually a 40 watt after 3 weeks.

Buy one of these dimmer cords.
You can just dim the bulb for less heat as they get older.
Lot easier to adjust then switching bulbs and no jacking with dome once you have it secured. Easier to fine tune to exact heat you want too instead of jumping from different wattages and done height.
