Bad News About the Growth Chamber . .

Today we put a wireless transmitter in the growth chamber and were getting pretty good humidity readings in the high fifties and low sixties. But when we put 8 incandescent light bulbs in the chamber, the heat went up to 36C . . and the fan came on to chill the chamber, which dropped the humidity down to 33%. So this time we were actually there to see what happened last time, when we had the 100% mortality. Luckily we were there to prevent catastrophe #2; we scooped them up and brought them back to the insect chamber, which tends to have a steady humidity in the low fifties.

We must not be doing something right, because there's another growth chamber in the room that's running at a steady humidity of 90%. Peter, the guy who runs the growth chambers, can expect an email from me very soon. Because right now, the growth chambers are defeating us . .
