Pretty standard with In House gear in my experience, and that's why I swore off their beans for a couple of years. I've grown out quite a few IHG packs, and have encountered herms in every one. Frustrating, but the lure of finding the one high quality stable keeper kept me going back.
Over the last 3-4 years I've bought and ran:
- Slurricane IX (2/5 herms)
- Platinum Kush Breath (3/5 herms)
- Jellysicle (2/3 herms)
- Divine Berry (2/5 herms)
- Triple Platinum Candy (9/10 herms)
- Bluenana (1/3 herms)
These were all babied in the same flower room with tons of other seed plants from other breeders that were all herm-free. After the 9/10 herm pack of Triple Platinum Candy, I very politely sent him a message on IG outlining my results with his gear, provided pics of the room, plants, and seed packaging. Didn't ask for replacements or anything, just relayed my experiences with his genetics, and he was a total dink in his response...... got super defensive, claimed all the strains I grew were thoroughly tested with no reported herms, had to be grower error, etc. I didn't even bother replying to his response, but stopped buying his seeds for a couple of years as I really didn't appreciate being brushed off as some noob grower when I'd been growing 20+ years and had spent $$$$ on his seeds.
I've grown out a lot of beans from a lot of breeders over the years, and have never encountered herm rates like I have with IHG. The only reason I have the JMO and Black Cherry Punch going now is that I got half-packs on sale for Black Friday for $60-80 each. There are some amazing plants to be found in a lot of his packs, and at those prices I can justify sifting through the inevitable herms to try and find them. I'll never ever spend full price on his packs again though, and I'm hoping I don't regret running the BCP and JMO. They will both be front and center in my flower room so I can keep a very close eye on them as I know what to expect.
