Hey there Underdogs, looks like I've got some catching up to do on the thread.. Underdogette and I have been out of internet range since just after my last post as our traveling shenanigans have continued as those of you who read our non-UD blog(s), follow our non-UD social media, etc already know. For those who don't just suffice it to say that many shenanigans have been, and continue to be, had. Ahh, thanks CC, much appreciated, we try! I know you already got past this a little bit after you posted this but I'll post here anyways. As an alternative to the VVPS I've had good luck with these adjustable wall-warts. No display screen but it's easy enough to make a mark with a pen (or whatever) at settings you like. https://smile.amazon.com/AUTOTOOLHOME-AC110V-Adjustable-Adapter-Electric/dp/B01JZMY50Y Ohhh cool graph and cool linked thread.. thanks man! Thanks Vito and happy to see you drop by! Hey Diggy long time no talk man! Glad to hear you're still enjoying the Air Core.. not many of those still around! I can't really add anything that Jcharles doesn't add below other than you might try some voltages in between with an extra long heat up time (like an extra 5-10 minutes) if you haven't already. Sometimes works wonders with difficult strains, etc. That said I'd try JCharles advice.. he's an UD Cloud Master. No joke check out the videos on his instagram. Just so! You the man... er... Dog?
