I use Gelatin 00 caps.
Do not get clear ones...they are a bitch to tell the top from the bottom.
The zon here has all kinds of them. Search 2 color 00 caps
You can even get variety packs of mixed color. I like that because i can make them strain specific with ground decarbed weed and kief.
I do make RSO caps but i will make 2 of those and take them right away...RSO tends to melt the plastic.
in an 00 cap i can fit
.30 to .32 grams of Kief or decarbed ground weed...take that long part and push it on the pile of decarb over and over til it wont take anymore.
.3 grams X
Kief at 30% = 100 mg
Kief at 40% = 135 mg
.3grams X
Bud at 20% = 60 mg
Bud at 25% = 75 mg
Oil i have to weigh out but i remember they hold more weight of oil. closer to .75 grams if i remember.
It mitigates that tasty bitterness from chewing them up.
