I'm not even sure if I have any photoperiod seeds left. Just a jar full of autos... but I think 4-5 non stunted autos should be about right for a 3'x3' table. I usually cram as many as I can for maximum variety.
I started with autos... in DWC, then moved to soil for a long time. Here's like... 40 plants in a perpetual 4x8. Used to pack em way too tight lol

Like 20 photoperiod clones in the 4'x4'...
Looking back at old grows, I've had better luck with photoperiods in hydroponics, and autoflowers in soil. I like the ease, low cost, and cleanliness of hydroponics. I've made this mediumless flood and drain method work for photoperiods, I really want it to work for autoflowers... but if I can't I'll probably switch back to mixing up soil in a couple grows...
