One thing is for sure!
Flux doesn't flux around when growing Meph!
And parsing_trees, you're just showing off with that crazy not so little HBSS!
Any Mephheads growing/grown any of these freebies?
Northern Cheese Haze X Sour Bubbly
[Sour Stomper X CDLC] x FORUM STOMPER
3 Bears OG X Double Grape
Maybe, but I've also got a Forum Stomper in a 1L next to it:
Like I said, there are six plants in the 2x2. Those two, a Toofless Alien, a Twisted Tree Crinkle Cut auto, and two Wicked Pissah! Blueberry XLs. The last three are in solo cups, but also about the same size.
I haven't grown any of those crosses you mentioned, but several people on the MephHeads subreddit have grown the Northern Cheese Haze X Sour Bubbly freebie and it seems to be a heavy yielder.
