First of all invest in two fans. 1 to put just about 2 ft outside the entry into kitchen and if you have another area the smell travels use other fan to blow out another window. I do this and have a renter in my basement suite and their place never smells, even during decarbing. Also, I hope you are decarbing your weed before use as you will get the stronger product to work with. I decarb always as when you have bud or shake its on THC-A form decarbing it changes it to just THC which gets you high or body stone depending, I put the oven on 215 F and slowly decarb the bud ( you do want to trim it down into a shake, this allows you to decarb all sides of the smaller pieces. I grind mine in an adjustable coffee grinder and put on the most course grind and tap it 2 maybe 3 times. Then take parchment paper. Line a metal baking pan with it. Spread your medium ground weed on pan evenly, then I check after 10 mins, then quickly every 5 mins. What you want is your weed to be just lightly nutty brown. Time can vary depending on how "wet", " sticky" "dry" and "strain". Once just turning nutty brown pull out of the oven. SLOWER IS BETTER SO TAKE YOUR TIME) NOW, to make your butter, #1 never add water to your butter, NEVER EVER. (I've never tried any that was made with water with the butter or the water & crockpot method that was worth even using that's how poor quality it was and a friend lost about 400.00 of chemo strain and had to use what they made into edibles. So when you melt your butter or clarified butter (its about 12.00 a jar but I mix with regular butter as well. But it boosts the strength of my butter as well as soy letchin(can find in any whole foods or try a cooking store, it also boosts your butter, just need a teaspoon & its cheap)) you want to keep the temp low. I use the #2 setting on the stovetop. You just want to see tiny bubbles around the edges. Then take your decarbed weed and add to your butter. Get a stool and music lol and sit down for about 1.5-2.0 hrs to stir.
I know there is some concern about some people are getting lighter colored butter, I found that this last batch was 1.75 oz in 1&3/4 lb butter. (I like to make capsules sized 00 you can order cheap from pharmacy. About 7.00 for 500 caps. I use for medicine) if you want to fill a bunch of capsules fast and the tops (only 3/4 full or cant get caps together.) I took a scrap piece of wood and a drill bit the same size as my capsules and drilled like 100 holes. 50 for bottom half 50 for the tops of caps. Then I take a syringe, you can get at the pharmacy for giving kids meds. I melt it slowly in a hot cup of water then fill my caps. I can do 50 in like 15 mins. Then after you filled them all, throw in fridge or freezer for 5 mins to let them set up some then it takes just 5 mins to put them together. So 50 caps, I take 3 a day. It lasts awhile and anything I may have dripped over lands on the board and I can scrape it clean after a while. Please, I realize everyone does what works best so dont shoot the messenger as this way of doing it has never failed me not one time. Also, if your caps look bright green and not dark green be careful as it doesn't always mean the darker the better. I used 3 different strains on my batch i just made and 1st time came out lighter green but potency is in the "are my eyes melting" range lol. I noticed that all 3 indica strains and bud i used were all lighter in color than some others ive had. To be honest i like the lighter green better, yes higher odor but less taste but i deffo didnt loose out on strength, so dont stress, if you did everything correctly, it should be fine, fyi i licked the spoon about half of what i usuallydo when making and i had to have a friend make me up somecaps for the night, i couldntfeel my eyes and yes, im very careful nottoo as im allergic to the plant hence why dont smoke it andcaps/butterlasts me longer than baking with it. But i use the dank in brownies, the brand with highest amountof oil called for as i have coco infused oil to, better for baking but save those dank balls,there is still alot of oil in it,so much so, i laugh when she said he/she puked from vapors. I did that after taking 2caps of what i just made the other day and 1&1/2 brownies i made from dank and i was on my face, thank the anti motion sickness over thecounter med,it will help but use with caution as mj repressess your breathing slightly, so i take zero reaposibility for that mention of gravol is what we have hear and can get in childrens strength. Cheers, i hope some of this helped ppl..ive been making my own butter for about 4 yrs, i havebeen helping out pharmaciesas it will be available soon and hopefully ins will cover if med
