Awesome!! You crammed some sisters in there! You doing hydro??? They look great!
Hydro, yes. It's a SuperPonics 12 XL (I bought a kit back in 2017) that holds 28 gallons of nutes for, as of a few grows ago, one plant. It takes some work to swap a res but I only do that every few weeks. That big res is extremely predictable and very stable. If anyone is considering hydro, this res has a lot of positives but I'd also take a look at the Current Culture Under Current Solo 13 Gallon.
I started growing autos but, since they're on their own timetable, I had little control over their size, per the first few pix. They kept growing into the roof area of my tent plus the long grow time (110-115 days) meant that I was giving them a lot of 45¢ per KwH electricity (Southern California) so I switched to photos this year.
The big, funky plant is one plant but the front "row" of branches wouldn't fit in the tent so I used either a Vipar XS-1500 (not the Pro) or a Mars SP 3000 to light it.
The plant that got bud rot is a photoperiod that was vegged under a veg light for 41 days and heavily LST'd. I shot myself in the foot on that one. With the extended veg time and the weather that was cool and moist, I was setting myself up for a fall. Lesson learned (the hard way).
