About a minute is how long should it take for cloud chasers. Preheat it for 40 seconds, then test your vapor production, I can understand heating it for a full minute if you want huge clouds on first exhale.
I believe the paper he gave with initial instructions said to preheat for 30 continue heating but start inhaling for 20, I've noticed waiting an extra ten seconds gets it's hot enough I don't have to do such a long draw.
But I will agree my Hammer also gets to a higher temp quicker and easier resulting in bigger clouds. But the Lotus has no heat limitation, combustion is far easier to reach for those butane powered vapes.

wisherly what is your technique? Have you tried increasing your inhalation speed, I've noticed bigger clouds as a result. Also do your countdown near a real timer versus in your head so we can get an accurate reading on how long you do preheat.
I'm sure this is knowledge known but ensuring you give more than a 10 second heat up when increasing the temp to extract your herb turning abv is necessary. Otherwise you will notice your cloud production fall.
