|Substrate, aka sand for aquariums,|
is sometimes packaged wet or damp.
I've also picked up bags of small shells that have a lot of moisture in them, which releases once you put it in a smaller container, soaking everything.
Wet flock is bad. Aside from problems gluing, wet flock won't flow or cover nicely and you'd be surprised how quickly you turn terrain into a mouldy mess when you have moisture in a sealed container.
So dry it!
So, this needed to be dried.
|I used Saran wrap here... while not idea, we had a LOT after the move.|
Place this all somewhere warm like outside. Hotter the better. DO NOT use your oven or anything else for food prep. Some of these special sands will emit bad gasses.
First, save the hassle and, use a funnel to pour the sand.
Second, only pour a little sand in to a flock container and pour the rest in to larger baggies than can be packed away.
JUST BE SURE TO CHECK THE WEATHER...
