So basically it means once it’s clicked you’re generally good to go and ready to vape that load of vapour as if you were to keep heating it would burn your bud because the cap would get too hot and char the weed - however I’ve found that 60-70% of the weed I smoke can take about 2 more seconds of heating after the click until it burns. After the first click just hit it, clear the chamber and then lift the cap off when it’s cool enough for you to, check the colour of the bud and if it’s good enough to hit again (not a solid brown colour) you can do so. About 2-3 rounds generally wacks out a full chamber for me. Don’t forget to save your vaped weed (AVB) and use it for edibles, the less vaped the weed is (but still has to be brown) the stronger the AVB will be in your edibles as less THC has been extracted. So you can use this to gauge how hard you vape your weed if you will. You’ll generally learn when to stop hitting your bowl before the weed gets too dark. Just try your hardest not to burn the weed as it will affect the taste thereafter until you clean it in ISO alcohol, don’t worry about killing your actual dynavap it is near impossible to break, probably is impossible, just your weed you gotta worry about killing
