I have a s1 and a f4 about halfway through flower and the s1 has a lot more branches and a bigger footprint. The f4 is pretty much just buds running up the main stem with not a lot of foliageAnyone that can give me a clue about how big @Jean-O blue dog gets? If these blumats in the smaller pots makes some giant plants like they did in the 10gal bags I may be crammed a bit tight in the 2x4!
