I have been wondering for awile. I seem to get higher yields from my hydei when culturing in plastic as opposed to glass. the media, amount of media and water, number of flies to start and temp are identical. The plastic containers have more rapid growth rates from larva to fly and the larva consume almost all of the media. The glass jars often have media left over as the culture dies out. I can only imagine that the plastic containers might allow for more air exchange and that the slightly drier media does better. Any thoughts?

my guess would be heat. plastic transfers heat a lot more quickly than glass. i bet that the plastic cultures stay warmer than the glass.

never thought of that

I can see that.

I use glass (pasta sauce mason jars) and I really get high yeilds. I find them easier to wash than the plastic. The only problem I noticed is that the media get really wet when the culture starts going. I usually just drop a rolled up paper towel to absorb the extra moisture.
