Echo Earth substrate & Tarantula Molting

I just bought a bag of the Echo Earth Coconut loose Fiber substrate like you suggested I should use to mix in with the other substrate soil I'm using already for my Chilean Rose Hair to hopefully help w/ the humidity & dry the damp substrate soil I still have in there. How much do you suggest I should place in there of the echo earth & mixing it in with the other soil? Also, when do you suppose I should expect my 3 yr. old male Chilean Rose to molt? I believe I read in one of my books around Feb. or March they begin molting again, esp. w/ the younger species.

I would start adding 1/3 of ecco earth to the substrate and after a little wait check if the substrate is any better. If it is still wet ad more ecco earth until the substrate is moist and not wet. That should do the trick.
Molting....I am waiting for a molt to, since I expect my rosehair to molt in early spring, you should be expecting a molt to (fits their natural inner clock).
