Hat alles super geklappt!!! Bezahlen ,Lieferung, und es war das drin was bestellt wurde…! Sehr gern wieder!!! Dankeeeeeee schön!!!
Found my first flushes were very blobby which I hadn’t experienced before with this strain, but I can’t complain, v good yields and potent fruits. Usually I’d just run two flushes toss it and start over but with this I ran em 4 times because it didn’t wanna stop fruiting
