Definitely use less than that a day. A cap (.5) lasts about a week or two in the omi carts (which has been said to lose about .2?? Citation needed?) But can PG be dripped straight in the hole and then close it up for the day or two? Or does it have to be used then and there? And is it sealed with a silicon ring (or other material). As someone said a few posts ago d-limonene bloats up some of those materials (just dont want to replace parts )
Thanks OF. Gotta get rid of the old Evo cart before getting anymore TV products. No more solids here. Only the gold.
I mentioned that limonene eats silicone. Teflon/PFTE is fine (but not as inexpensive, or as flexible as fluorinated rubber).
How much a DART can hold is a matter is how much you want to abuse your batteries and possibly the oil. The past two weeks, when I go out I've been loading 1/4 to 1/3 g, which definitely floods the unit - It take much longer to heat up and tastes a bit burnt by the end, but still doesn't leak! BTW. This is a "dirty" oil that immediately fouled two Omi carts AND I've only been doing this because I've had to be relatively far away from home most of several days.
For the best taste (and battery life), follow OF's well repeated "load small and often" is absolutely correct - It sounds like you'll be able to follow that advice pretty easily (sorry, but I just consume too much, and whatever I inhale is small compared to other methods of ingestion).
BTW. Butane in a freezer, like any volatile flammable fluid is "just a matter of time". In a can, you'd probably be OK, but I wouldn't try it (imagine a summer power outage, the can warms, then the power comes on and the ice maker motor sparks.
At best, you might be lucky).
