Hey guys

I bought 2 P.Metallicas. They're really small, not even blue yet.. the one just went through a bad molt, long story short, I attempted to rescue him, he survived, now has 3 legs remaining Its been 10 days since the incident, hes still alive, I'm just waiting for him to start feeding again so we can get him back to 8 legs

The issue, which I now know.. is the lack of humidity.. I watched this vid , but its summer time now and I dont think a heating pad is a good idea.
I like the idea of a fish tank, which creates the high humidity, and putting the spiderling enclosures inside the tank..

Please could I have some tips/advice (a real dummies guide with step-by-step instructions would be orsm) on how to create a high humidity enclosure (80% hum) and not have mold problems.

Thanks

Humidity does not really help your spider molt, it is all to do with the internal hydration of your spider.To molt the spider uses ( I will find the name just now) a fluid that he pushes between it's old exoskeleton and new exoskeleton,
if your spider is not properly hydrated this is what cases bad molts, as you spider dries/hardens up faster than normally.

So with a molt, you need to make sure there is water source and your spider is feed as the spiders get some of their moisture from it's food.
The key is tio mist the spider every 3 days and to make sure you remove any old or uneaten food this will prevent mold.

Heating pads in summer and a molt is the fasted way to kill your spiders without even trying.
Misting your babies will be fine.

OK cool, that makes sense.

Do I just spray the side glass? Do I spray the soil too? Shouldnt the soil be constantly damp? At present, its constantly dry.

That is the problem, get your peat moist, while they are slings and molt on regular bases it better to keep the peat a bit moist .

So peat moiste, not to wet though.
And then you can mist the sides of the enclosure every 3 days, just 3 pulls of the trigger.
Also just watch not to make it too wet with this method.

Will mold become a problem? How can I prevent that?

Also, I've noticed white powdery-type spots appearing on the side of the glass.. I'm going to change all the enclosures tonight to start afresh, I'm suspecting its some sort of fungus..

That should be spider poo, all arboreal's species like to poo on the side of the glass.
Just use some water to wet it then your finger or paper towel on the end of tweezers or paint brush, just becareful not to get bitten with your fingers in the enclosure.



Here is a very nice photo showing you what it looks like.

As long as you have ventilation you won't just get mold, also you need to keep the peat clean from any uneaten foods or dead feeders.
If you do get mold you just remove the affected area and replace with new peat, nothing to stress about to much.
