I’ve only been once, I got my ftp and decided to get cartridges for my bogo. I was on my lunch break, so didn’t really have time to examine the cartridges, but when I opened one up for use later I noticed how runny it was. I’ve been using cartridges for years, long enough to know that runny concentrate is not the best composition. I might give them another try to see what they have to offer flower wise, but I won’t be getting anymore cartridges.
