Hatchrite is sold online by several suppliers, but the original person who markets it is Alex Hue.
I think it sells for around $12, but I was lucky enough to find it for $8 per bag online. The bags are 2 pound bags. I used about 1 1/4 - 1 1/2 pounds for each 6qt tub. Hope this helps.
If you attend reptile shows you can often find a vendor there selling it. If you attend the monthly show in Taylor, MI I believe one or two vendors there generally have it available.
I poke small holes in the bottom of my egg tubs so the excess water drains out. Makes it fool proof.
And for substrate i switched to Calcined clay. It holds on to water longer and its easier to tell how wet it is because the color changes from light tan (Dry) To dark brown(Wet)
It helps keep the humidity in with the eggs without a lot of condensation dripping down on them. We air our eggs by removing the lid and lifting a corner of the cling wrap about every 3 to 5 days. Once they hit day 45 we remove the cling wrap all together and just pop the lid every day for a few seconds to air them (you'll see a lot more condensation developing at this point as they approach their hatching date).
Talking about the condensation dripping. I have seen this method(cling wrap/press-n-seal) but I have noticed sometimes it will bow towards the center of the wrap which will direct the condensation(droplets) towards the center where the eggs normally are. Then you have drips on eggs. Please elaborate on how to prevent this so those going to try this method do it properly. (like me possibly.. )

If this is the case, I would lay a couple paper towels on top of the eggs. Would that be ok?
