Just got done with a fem WW from greenhouse grow. Had some MASSIVE colas with a fairly good yield. I grow organic soil tho, so I'm sure your hydro system will push em to the limit. They seem to me to be generous feeders, and I would try to keep single colas, in my grow, the topped plant yielded significantly less overall.

Be vigilant in your search for hermies. 3 out of my 5 pack were hermied but didn't really show until later in flower. Forced me to harvest just before 8 weeks, and I was hoping to push them to 9. Only 25 or so beans in about 7 oz, so I got pretty lucky.

Best of luck to you here and I'll be keepin an eye out.
