Can’t get any vapor on any setting …

[Gramula]

Hi new member here. I have a Sai-type atomizer on an older sub ohm box mod without TC. Does anyone have any experience with what airflow setting / wattage setting seems to work best ? I am at my wits end. For some reason at 12w it does not produce any vapor at all and at 36w it immediately burns through a serving of my concentrate. I am using premium cold pressed rosin from a local dispensary. I tried 25w last night and it seems to work the best. However I still could not consistently produce vapor. Thanks for any assistance and apologies if this has been discussed but I couldn’t find a solution.

I'd use between 18W and 25W, I find you have to get your draw technique and heating to work together to get consistent hits.
