Eekman got it spot on when it comes to temps, it is all personal preference and the kind of high that you want. You can vape anywhere between 180-210C/355-410F, best temps to release a good range of active compounds is at about 185C/365. Any temp from 180C/355F-190C/375F with give you a good cerebral high and anything over that will increase the body stone effect. Also as Eekman said be careful going to high as it can cause combustion and create smoke, so even though you can vape at 210C/410F its not recommended to go above 200C/392F.
As for the vape in the bag, i use the plenty and it has a whip system so not got any experience using the bags, but done alot of research online before buying my vape, and most people seem to say that the vape starts to go stale and lose potency and flavor after about 10 mins in the bag.
Here is some info i copied about the different vape temps of cannabinoids, flavonoids,terpenoids and toxins and the uses they have.
Cannabinoids
THC - 157 °C/315 °F.The most famous cannabinoid. It has both euphoric and analgesic effects, inducing a great sense of relaxation.
CBD - 160 - 180 °C/320 - 355 °F.
The cannabinoid most sought after by medical users for its vast array of medicinal applications. It partly counters the effects of THC, effectively countering feelings of anxiety and paranoia.
Delta-8-THC - 175 – 178 °C/347 - 352 °F.
This cannabinoid is very similar to THC, but it is more stable and less psychoactive. It has great anti-vomiting properties.
CBN - 185 °C/365 °F.
CBN is often found in quite small amounts, however, its effects can still be felt. It breaks down THC and is highly associated with a sedative effect.
CBC - 220 °C /428 °F.
This cannabinoid has anti-inflammatory and anti-fungal properties.
THCV - 220 °C/428 °F.
THCV has been shown to moderate the psychoactive effects of THC, but more research is required.
Flavonoids
Beta-sitosterol - 134 °C/ 273 °F.
This flavonoid is thought to have anti-inflammatory qualities.
Apigenin - 178 °C/352 °F.
Apigenin is thought to be estrogenic, anxiolytic and have anti-inflammatory properties.
Cannflavin A - 182 °C/360 °F.
This flavonoid is a COX inhibitor.
Quercetin - 250 °C/480 °F.
Quercetin is an antioxidant and anti-viral flavonoid. It boils at , well out of the cannabis vaporization temperatures.
Terpenoids
Beta-caryophyllene - 199 °C/390 °F.
Thought to be anti-inflammatory and anti-malarial.
Alpha-terpinol - 156 °C/312 °F.
This terpenoid is an antioxidant, sedative, antibiotic and anti-malarial.
Beta-myrcene - 166- 168 °C/330 °F - 334 °F.
This is analgesic, an antibiotic and anti-inflammatory.
Delta-3-carene - 168 °C/334 °F.
This terpenoid has anti-inflammatory properties.
1,8-cineole - 176 °C/349 °F.
1,8-cineole increase cerebral blood flow, acts as a stimulant, and is anti-viral, anti-inflammatory and an antibiotic.
D-limonene - 177 °C/350 °F.
Perhaps surpringsingly, D-limonene appears naturally in cannabis. It has anti-mutagenic, antidepressant and immune system potentiating properties.
P-cymene - 177 °C/ 350°F.
P-cymene is an antibiotic and an anticandidal agent.
Linalool - 198 °C/388 °F.
This is an antidepressant, sedative and immune system potentiator.
Terpinol-4-ol - 209 °C/408 °F.
This is an antibiotic and an AChE inhibitor.
Borneol - 210 °C/410 °F.
Borneol is an antibiotic.
Alpha-terpineol - 217 °C/423 °F.
This terpenoid is a sedative, antibiotic, antioxidant and AChE inhibitor.
Pulegone - 224 °C/435 °F.
Pulegone is a sedative and potentially has memory boosting properties.
Toxins
Carbon monoxide and tar
Released by combustion in the form of smoke. They are carcinogenic and can cause lung related problems.
Toleuene
This is not thought to be a very serious toxin, and only appears in small amounts. It can cause light-headedness, nausea, sleepiness and a loss of appetite. Its boiling point is 110 °C/230 °F., so there is no avoiding it.
Benzene
Benzene is a carcinogen and has a boiling point of 200 °C/392 °F.
Maphthalene
This toxin is possibly a carcinogen and causes light-headedness, nausea, loss of appetite and pale skin. Its boiling point is 218 °C/424 °F
