Advertisement This is probably most important for breeding but in terms of Ts growing from sling-hood to adult would one want/need to create seasons? This being light shifts, temp variation (including a "night" temp), and wet/dry seasons. I already have to heat my Ts artificially as my house stays around 60-65* f which is much too chilly for them. My micro-climate is currently in a room with no windows (stupid I know, working on it...) so i have a dim lamp in the room on a light-dark cycle. I figure if I'm already doing artificial lighting/temp regulation I might as well do it "right" if need be. I guess my question is... do slings/Ts need 'seasons?' Does it help them in any way? Or would I just be doing it for my own peace of mind to create as realistic an environment as possible and make myself feel better about a captive animal. I mean our critters (tarantulas and others) already adapt to so many abnormal things, I feel like a lot of animal keepers do unnecessary stuff to make themselves feel better when really there's no ultimate benefit for the pet at all. I found a graph (attached) that is supposed to be similar to what my current Ts would experience in the wild. However I don't know if this info is accurate and I'm not entirely sure I'm reading it right.... I have one Lampropelma 'sp' "Borneo Black" 1" and one P. Metallica 1.25". So I guess question #2: Would this graph be accurate for these species? Can anyone help me out and share how to read it? Preferably someone who knows Celsius and mm because I live in the USA and am not particularly familiar with either of those units and I'm not fond of spending a load of time on google fussing with conversions. Lazy I know :/ Mostly interested in if the graph is accurate to the species I have though. Thanks in advance mates!
