Really doesn't make a difference to me how they do it really, just as long as what they're putting out is dank...and so far everything has been.
I've got 4 IHG strains currently in flower (Switchberry OG, Tahoe Sap, Buffalo OG and Erkle OG) and another 11 IHG strains in veg (Purple Hulk, Twisted Velvet, Crystal Cookies, Platinum S1, Blackberrium, Silver Pie, Alien Vision, Platinum Gorilla, Platinum Buffalo, Diamondback OG, and Bubba X). So far, everything in flower is looking stupid fire with Switchberry OG and Buffalo OG being the standouts.
I see a lot of gripes and complaints about IHG and I'm in no way trying to say those complaints aren't justified, just that my experience with IHG has been nothing short of terrific. Like I said, everything I've run from them SO FAR has been fire...excellent germ rates, crazy resin, really interesting terp profiles and no hermies as of yet.
I'm not associated with IHG in any shape or form by the way and have absolutely nothing to gain by giving them an undeserved favorable review so you can trust the results I post are genuine, be it good or bad. I'll have plenty of pics of everything listed above to backup it all up as well.
