Hello Spanky, sorry for the incredibly late reply... here's my preferred method for making cannaoil:
Preheat oven to 240
Grind 1/4oz flower or 1oz trim
Spread grinds on foil-lined pan
Bake on center rack for 30 mins, stir, spread, bake another 30 mins
Add 1/2c or 1c clarified butter or coconut oil to slow cooker (1/2c butter per 1/2oz bud)
Turn on low to melt butter/oil
Remove grinds from oven, cool 10 mins
Spray or sprinkle baked grinds with 1t soy lecithin granules, stir
Spray or sprinkle baked grinds with 1t everclear or high% alcohol, mix, spread grinds, rest 10 mins
Add grinds to slow cooker on high (low if not using a water bath) for 2-8 hours (depends on dryness of matter)
Squeeze liquid from grinds with French press, strainer, or cheese cloth (nylon is best)
Cool liquid to room temperature, then refrigerate overnight in a bowl or open mouth container, do NOT freeze, do NOT use a jar
Unrefined coconut oil has a coconut flavor, refined coconut oil does not. However, I hate coconut flavor but the unrefined oil is moderate enough for me... surely depends on preference. Olive oil is possible, but you won't get as much extraction. I can go further into it, but basically different oils and butters have different fat contents... THC attaches to fat molecules... coconut oil is most versatile with a very high fat content. I've done side by side compares of ghee and coconut oil and the oil tested
with up to 100% more THC extraction. I defoliate with GWE recommendations from Nebula's and Sirius's blogs... as much as the plant will handle without suffering... and I save and use all leaves.

I don't defoliate sugar leaves until trimming during harvest... they're too close to buds to risk damage.
I'm happy to share what I've learned if it can help anyone! Best wishes in whatever you decide to try!
