Ok guys, there seems to be much confusion about this vaporizer and how to operate it. I am a vaporizer user and medical user of nearly five years and have used pretty much every vape out there...My father owns a volcano which we all know is a similar bag system.
Okay, so about this burning of your guys herbs where are you guys placing the herbs in the cyclone bowl? You should not be experiencing any burning even at 350 if you are putting your herbs on the top of the cyclone bowl so that would be the side with the black on the top of the bowl. I vape starting at 340 and work up to 350 with no combustion the herb doesn't even turn brown it turns just before brown. I put about .2 in each bowl which I have found gives me the best vapor quality in thickness and taste. I usually get around 5 bags for each bowl 2 of those being with the bag they provide with you and the other 3 being in a much larger reynolds oven bag. If you put you herb on the bottom of the cyclone so it is touching the glass tube I find that 270 is around the temperature you should use but I always put my herb on top it is definitely better I only put concentrates on the bottom side because those need a higher temperature to be effectively used.
Also yes, after the first bag you will have extracted all or most of the flavinoids out of your herb and the remaining 3 or 4 bags will not have the flavor quality of the first bag but this happens also with smoking and with every other vaporizer on the face of the planet.
You should never fill you cyclone bowl higher than the black rubber that is on it or you vapor will not be as good because the bowl will be over packed and airflow will be restricted.
Also While the bag is blowing up I find it works well to tap the side of the vaporizer not the glass which causes the herbs to stir itself on fan setting three making no need to use a stir rod.
I use fan setting three on all bags until my final one. Remember just because you are not exhaling vapor doesn't mean you are not getting any there may be little left in the bag and all gets absorbed into your bloodstream. I find it is also most cost efficient to hold in the vapor for as long as you can because any vapor u are blowing out has high quantities of thc and very little undesireable by-products.
I know I rambled on this as I am medicated during this time
off a delicious OG Kush bowl that I also mixed Sour Diesel into(gotta love cali). If you guys have any questions about this vaporizer or really any other vape but the aromed let me know your questions and I will try to respond in a timely manner.
I hoped I cleared anything up for you guys
