Wow, lol, and people keep..., not fair at all.
Anyway, I didn't believe till I tried, it is only $45 at my local store, you don't even have to use both bood and ignitor, just buy the blood and try. You may not cut it 3wks, but at lease 1 wk for sure. If you don't see any different, there is nothing to loose, just return it to your store and get your money back, they clearly have it on the label.
I don't like AN at all, but it is the only thing I know that can replace for PGR right now (for the part forming early buds). I've never tried AN nutes before because I don't see much advantages beside the PH perfect. However, I always listen and try something new when I find it reasonable which is why I tried bud blood. Of course this is not a good habit if you don't have enough knowledge, I paid my price sometimes . This round I will combine it with Ignitor to see if there is any different as chillin method.
Since you never hear bud blood I assume you don't know what is the "vitamins" that chillin been using in his nutes. So I have the right to assume you never had a really good crop. Unless you use something like full line of nutes from some nutes company, your buds potency can't compare to chillin because from my knowledge, I can see he is using mostly all the supplements which a full line nutes can offer.
I think you mainly focus on cooking some trichomes you buds can offer to make them best while we try to make tons of trichomes... You know what I mean? You have 5 trichomes / grade A+ while we have 10 grade A, we can't wait to get + because too much trichromes make buds rot. It is not from ventilation, we passed that point.
