I am going to make an oz of low-mids into caps this weekend

I have had success making caps in the past and want to try your method. I used to use a toaster oven set @ 175F and put a candy thermometer in the mix to monitor. I try to keep it around the 175-185 range for about an hour total, stirring it a couple times throughout. I usually do it next to my computer while I play Counter-Strike and mix when I have time.

I'm going to use about 25g of $170/oz buds (I need some to use in the vape while cooking :jointsmile to make the caps. I was wondering how much coconut oil to use. Before I've used enough olive to cover the ground bud and make it into a paste (about .48 tablespoons per gram I read somewhere).

What do you guys use to eyeball the amount of oil needed? (probably posted 5 times already but I must of missed it)
