I'm learning all about Jacksonii as I'm the proud owner of one for about 3 months now!
I don't have a Veiled but I have read up on them because I was considering them in the past.
1. No not the same, Jacksonii lives cooler and 'requires' a big temp drop (to ~60F) at night...
I've put required in '' because some people keep them warmer but in any case it should be under 70F. Younger ones do better in the higher temps, adults will probably require closer to 60F...
Just shine a light in his eye at night, if he wakes up after a couple of seconds he's not resting properly and it's probably to warm. If he stays asleep your OK. (I use the LED flashlight of my phone for this.)
2. Cage enclosure, it's demand for ventilation is also greater than that of a Veiled.
3. Baskin temps, I keep mine at around 80F under it's basking spot. Room temp in the lower regions of the cage is fine. I use a 50Watt basking lamp and a 26W spiral UVB lamp
4. Dusting I think is the same as veiled.
6x week calcium 1x vitamins, 2x a month calcium with D3.
(I'm not doing the D3, it's a choice and a matter of opinion)
5. It needs to be kept more humid as a Veiled too. 50%-70% at average. For mine I keep the whole room at 50% with a humidifier and he gets sprayed 3x a day automatically and sometimes I spray him myself with hand-warm water because he enjoys it so much... You can also put it in the shower sometimes (I will once I find a big enough Ficus tree)
6. Read care sheets, even tho they seem to differ in opinion quite often you can pick out the useful stuff...
