I am curious now about the Orchid. I watched a video on You Tube by the Black Guy who does a lot of swearing. I am sure you know who I mean. I really like his videos. So with the Orchid and dual coils are you always sub ohming. I only have one Mod capable of that which is my Sigelei DNA20 clone. I am wondering the way you increase and decrease your juice flow by not screwing the chimney on all the way seems like a hassle if you get it wrong you have to tear it down. Also is it as good as the KF or is it just another version except for the fact it looks real easy to run dual coils.
I don't have an Orchid, but you can definitely run dual coils at 1 Ohm or greater. I do it on my Kayfun Lite. It's harder on the Kayfun because you have to squeeze the coils in side-by-side and you only have two posts to attach the four coil ends to, but you can definitely do it.
Basically, if you build a 1 Ohm single coil, you have a certain number of wraps. If you run two 2 Ohm coils in parallel, you end up with the same 1 Ohm result, but each coil will be twice as many wraps, and there are two of them, so you end up with 4X the surface area of coil touching wick. If you run both 1 Ohm builds at the same power (or on a mech mod), you'll be delivering the same total power but at a lower temperature. This prevents the juice from tasting burnt or off. I'm a big fan of running bigger coils at lower temperatures for the best possible combination of vapor and flavor.
