My Jean-O's have been big hungry girls lol. I've got a Where's my Dog in a 1gal that I topped at 3 successive nodes. She takes up my entire 2x2. I've also got 2 WTF going, one stayed rather small and the other is 3' across
The one that stayed small was kept in a 3" pot till she was transplanted and topped right at the same time as she showed sex. The other was transplanted at the same time but was developmentally behind by a few days. Goodluck! Double Grape tends to be wider than she is tall from what I've seen. I had 7 in my 2x2 for a bit and that was intense even with super heavy training and repeated toppings. I ended up getting about an ounce from each but I had a lot of issues. I specifically chose strains that were supposed to stay small, were trained heavily and topped a bunch, and it was still tight.
