I'v bought a 5 pack of the ChemDog from GHS, It was horrible! Total crap IMO. Waste of time and the money spent on it. It wasnt even just me that dis liked it very much, My wife even hated it and shes not picky at all. It grows very sativa like, Looked absolutely NOTHING like the true chem dog. Took 12-13 wks to grow. It grew more like GHS SSH, even had a very similar scent and taste, If I had to guess GHS Chem Dog is either a cross of there SSH or they just gave me SSH seeds in Chem Dog pack. I can also say GHS SSH was pure SHIT! not good at all f**kin horrible! Im not trying to hate on GHS because I have had some good luck with some of there stuff like The Bubba Kush was pure FIREEEE, Not true Bubba but f**king amazing!!! There Train Wreck was killer also. I just hated there Kaia Kush, Chem Dog, and SSH, Which IMO are all crap strains that have been hyped up by Arjan after he Bought the cup from high times (Trans High Corp). I have had mersh stronger then those 3 strains. GHS Green-O-Matic was OK better then mersh but not better then besters. IMO go with TGA Seeds, DNA, or Rotten Apple Seeds. Those 3 have been the best so far. All of there strains have been fire. Only problem with Rotten Apple Seeds Is you either have to know the guy to get them (Samples-Tester Packs)or buy them at auction sites or in person in med states. Every strain I have gotten from RAS was one of the best ever but they were hard to aquire at first. I have been testing seeds for them for about a year now and everything iv tested has been amazing! They do have a rep on RUI that might hook you up with freebes if you ask them the right way. I would suggest buying Herijuana from Sannie but Sannie now requires you to sign for your package which is not a smart thing to do because it can be used against you if your package gets caught. Good Luck on your grow and finding the best strain for you.
