very nice, thanks for posting them up!
hi zach, not sure how you are growing these bubba S1s but they can be quite vigorous in a decent soil and large containers. the growth stalls very quickly once they get anywhere near rootbound. best to grow them in a tried and tested soil mix that you know plants do well in.
i'm sure they can do well in hydro etc too - i just dont know much about that!
let us know how you get on,
VG
