can't clone autos... and can't hold plants in veg.No, the best use for autos is continual harvest. I run a strain that finishes in 60 days or less and gives me 3+ ounces per plant. my best from a 70 day auto so far is 7 ounces. don't discount autos for any reason! and is is without a doubt top shelf bud. Autos grow slower in a greenhouse/outdoors so I prefer them for indoor grows.
I'm currently growing an Auto Ultimate from Dutch Passion. I'm hoping for a least a pound, but these tend to go 90 days. I have however seen one grow of these hit 998 grams!
Autos are not needed to control height, just need to know how to control the plant. If you have short growing space, then flower your clones earlier, get a taller grow space, or specialize in strains that are naturally short.Not necessarily. Due to being able to use long day length, you may be able to get shorter plants and more weight per plant and possibly more resin. You could experiment and find the exact day length that produces highest yields, since you can use whatever you want. The only downsides are higher power usage and having to take whatever phenos you get from the seeds. I was really just using autos as a possible way to test my theory that long nights cause stretching though.
Both of you are ignoring the absolutely best feature of Cannabis photoperiod control of flowering.
