Hello and welcome!!

If your BP has been eating and shedding fine, then I would say that the temps are good and you may not need a gradient (besides what is created from the slightly differentiating temps from day to night). Just make sure that you are able to accurately keep track of them as well as the humidity. But if everything has been fine so far then I would just keep it as is, although you may want to keep an extra close eye on temps, etc. once you get the new enclosure done.

Off topic.... what part of the Phillipines do you live in? My mom is filipina and I am mestiza. When my dad was in the US NAVY, we were stationed in San Miguel as well as in Subic Bay, Olongapo..... until Mt Pinatubo errupted and they shipped out all of the dependents. I don't think that either of those bases are still there...
Unfortunately, while we were there there were very strict regulations as to where military could go off base. Mainly spent time in Olongapo although we did take a couple of trips to Manila. My mom is from one of the smaller southern islands (sorry I can't think of the name) where she is currently building a house and is wanting to take us all back there so that we can see a lot of the beautiful places that we had missed while we were stationed there. I have tons of family there that I have still never met, although I had met many many of my aunts and cousins while I was there. I would love to go back, although I may never come back home if I do . Very beautiful country, and some of the best beaches I had ever been to, although I think all the jelly fish there hated me and made it a point to get me everytime!! LOL
Okay enough of my reminiscing and ranting.....Welcome to the site!!!
