I had 7 g of flower that I gently broke up and put into 1 cup of coconut oil and put into my oven at 275 (for half an hour and then) 225-250 for 3.5 more hours with 1 teaspoon of sunflower lecithin powder mixed in

I took it out and popped it in my freezer for 2 hours then pulled it back out and twice strained it with very fine cheesecloth

My boyfriend says I made it wrong and what I now have is a cup of extremely weak infused coconut oil if even that.

so whats the verdict did I just ruin 1 cup of oil and waste 7gs of flower?

I did it this way because I found 3 tutorials online that said I could decarb my flower in the oil itself, were those wrong??

For reference this is 7g of THC-A Hybrid Sativa that claims to be 32.36% thc

edit: I havent tried it yet
