I’ve grown 19 meph strains. Gold glue and 4 AM r power houses. I believe both tested over 25% and it shows. I loved double grape but it didn’t hit as hard. That for me could be a terp thing both gg and 4AM r very heavy in the terp dept and DG is more mellow. I think DG tested at 27% still didn’t feel as strong. Other things in play other then thc. This may change as I have a forgotten cookie and two orange diesels going. Oh almost forgot about sour crinkle, also very powerful.
