Greenhouse do have some good genetics. That is not the issue. The issue is that Greenhouse will sell you something that it's not. Such as selling you "exodus cheese" when it is not in fact exodus cheese. They give their strains names of famous strains knowing that those name will appeal to someone. Any other marketplace it would be in violation of various trade description laws but unfortuantely people do not own patents to cannabis strains etc so certain groups use the opportunity to make some things up in order to get a bit more cash rolling in.
The issue isn;t that theOP had crap weed, but that it wasn't the weed it was marketed as. Imagine buying an expensive organic chicken, that was actually found to be a battery farm cchemically fed chicken. Even if it tastes great, i;d be annoyed, i paid for organic.
