Before you make any extract you need to decarb the herb first. Do a site search of decarbing herb. Good luck! Just ordered one my self today from their own website. If you go to their Facebook page they got a great coupon code currently.
This is true, but the magical butter machine decarbs your bud for you
Definitely fresh frozen for bubble, but for butter you will want to cure the bud before hand.
This machine strips a lot of chlorophyll due to the intense grinding feature and constant heat, so I would imagine if it was fresh uncured bud it would be very green
Could be wrong I've only used dry buds in the machine
