@hassan there are two types of capsules. A straight up one and one that comes with a smaller version of the concentrate pad. The ones in the capsules are smaller and can be bought as part of a set i.e. the capsule and pad or separately i.e. just the pad.
To use the concentrate pad and the capsule for a micro hit I simply remove the concentrate pad from the capsule, add a small amount of herb and then replace the pad. Its up to you if you put the capsule lid back on or not. The same result can be achieved by just adding a little herb to the bowl and then use the bigger concentrate pad to hold it in place... your ready to vape away with your nice micro dose
Yes a very small amount can escape the capsule lid. I found the best way to avoid this is simple use a slightly courser grind, solved the problem for me
The finer screen is for the bowl (at the bottom) and the courser screen is for the CU. I have read of people using the finer screen for the CU but apparently it can cause more THC to condensate in the CU due to the airflow changing thus meaning you don't get it. I don't know how much THC is lost but its your call, its your vape and your experience... just rock it how you want to
Not really sure what you mean by this? Do you mean the mouth piece attaching to the CU? If you do I haven't noticed any difference but I've only had mine for about 3 weeks and still learning. If you want to increase resistance both the conc' pad or the capsule will do this slightly but I just think low resistance is the nature of the beast.
Ha ha yes it can be a creeper. I've found the variety of herb and the temperature you use greatly affects this. You want a hit rather than taste (although there's always some taste) just use a higher temp
Hope that helps, but please bear in mind that I am no expert and new to the mighty as well
