Wow yeah. I think we may have to double the years if we're going to compare to aloe plants in areas where they are garden plants.
Assuming you put them outside and acclimate them to as much sun as they can take during the warmer months, here in my garden, we're still talking less than 5 months... more like 4 months during which they can go outside and even then they don't get as much of the the extremely hot/warm (or perhaps extremely hot daytime/cool night time?) conditions, and 7-8 months inside. They may get little longer growing days IF you provide them a lot of light (as in supplemental lights) and other conditions (humidity?) they need to extend their growing season, otherwise, they just shut down for the winter in the "dim" "dry" "cold" winter indoor conditions.
I think they might also need the cool period and the drought period.
(I think these are the same reasons tropical fruit trees take so long to get to fruit bearing maturity here.)
What kind of aloe varieties do you all have? I was looking at some cool photos of Spiral Aloes but found out they need to grow huge -- like two FEET across... in TEN to FIFTEEN gallon containers -- to look like that.
I did read that seed-grown Spiral Aloe can develop their spiral earlier -- I wonder if they are hard to grow
