Have only tried the early bud from #2 so far - fruity, melon, skunky. Good but nothing special. Will have to update once the others are cured out, I wanted the early bud to be sure it wasn't all too heavy and probably erred on the side of taking it too soon.
So, I took #3 down F81, (60g wet, 17g dry) and just took #1 down on F88 (270g wet, estimating 67g dry). Some hermaphroditism on #1, only really seeded the popcorn so some of that just went in the trim bucket rather than mess with it. Will ice water hash that.
Overall happy with it for what it was. Wouldn't run the three plants in the 2'x2' again but as a first grow in awhile to minimize veg time and not put all my eggs in one basket it worked out okay. I definitely had issues with overfeeding and pH, had a drainage blockage drown #3 for a day or two during the stretch, got frustrated with how touchy the 1 gal. hempy buckets could be. That led to me switching to DWC for the next run (already in flower), I may give a single 3.5 gal. hempy in the 2'x'2 next time but I don't know. I think I like the system I came up with for the DWC where I use hempys for veg then just flip them to the DWC a week or two before flowering.
