I thought about getting a gsc cross but I didn't know if they would be bigger plants or not and the critical kush was that barneys strain IV looked at it to was it a good couch lock
I grew them both indoors for a few years before trying them outdoors. I like them both a lot and would recommend them.
The GSC was from Cali Connection. GSC was very finicy indoors and seeded up once on me, it also grows in spears that like to get really tall so I had a lot of trouble with it. Outdoors though it was a dream to grow. Low maintenance and lots of easy to trim golf ball sized buds. Just tie up all your branches because they break easy at the connections to the main stalks, it grows very tall also with most of the buds on the top. The outdoor quality was top notch and is generally the favorite with my friends.
The Critical Kush was Barneys and wow it is a producer. One of my best ever, indoor and out. It grows in a big round bush structure with a crazy amount of buds equally all over it. I had lots of mold with it, but we also had torrential rain the last two weeks of harvest and had to harvest them early, so its hard to fault the plant to much (the GSC next to it had much less mold and still harvested less per plant). Indoor its 100% fire, outdoor it was A-/B+ which could probably be improved on.
I liked these strains both so much though that I have Cookies Kush and GSC from BC buds to try in the near future.
