I was wondering how often a T is supposed to molt...once a year?? I am not sure so i am asking...I also have had my A. avic for a year and a half and it has molted once.....Normal??? I have had a G. rosea for a while now and I think i got it after a molt....but what must i do to encourage a molt..moisture, temp., food?? or a combo of them??

as they get older, they molt less and less... it all depends on evironmental conditions, i believe...

i am one of the people that basically thinks there are a number of set molts in a T's life.. and you can speed that up or slow that down, depending on their conditions.. I mean, this HAS to happen in the wild alot... the weather is NEVER exactly the same each year..and population distribution of the predator/prey cycle..

man, alright.. getting back to the point, how old are your T's? Rather, howbig are they?

you can't neccessarily speed up a molt, but you can powerfeed, and raise the temp to engage the feeding response... the more the feed,the bigger they get, the more they'll molt is how it BASICALLY / THEORETICALLY / GENERALLY goes... it works mostly for slings and juvies...

once they get older, however, there tends to be longer amounts of time between molts.

i dont like to powerfeed my slings.. i like to feed them more than i would my adults, but not powerfeed.

good luck! (how big are your T's anyways?)

My A. avic is adult, her size is about 4 1/2 - 5 inch leg span, my G. rosea is just a juv. yet, about a 3 - 3 1/2 inch span, and my H. lividum is a full grown adult about the size of my hand...and i am 6'1"..so go figure the size..cause i aint getting that close to it... (she's mean..!!! :))

Would you think if someone powerfed a sling to adult size.. would it still molt and just not grow? ive never seen a powerfed spider.. so i dont know how it works after they reach full size:confused:
