I get 2 of these guys tomorrow (1/4" slings) and I am curious as to how long they take to reach 1"? I just want to know what I am up against growth wise, since there is limited info on the web.....

from what i understand they reach full size in about a year...which can be up to 11" legspan. I have one that ive had for 2 months now and it had just freshly molted when i got it, and its getting ready to molt again, and right now its at 4" legspan. 

EEEEK!!!!!!  

What and how often do you feed?  I am hearing both sides- crickets and roaches...  (EEEEK!!)

right now i feed it crickets but will throw a roach in there when it reaches a bigger size

LPs are super fast growing Ts. feed em just about anything thats their size or smaller. it only took about 2 years for my original to grow from 1/4" to a 10" adult...mine turned male   =(
