m0useanswered grow question 4y ago I was always under the impression when its an AUTO, they talk about its full life veg+flo as their is no light switch, just 18/6 its on autopilot.
But when its an PHOTO I think its whenever you switch the lighting to 12/12.
eg. one breeder says indoor flowering time on a photo strain is 55-60 days.
that's only 8,5 weeks. I feel its to short for a full grow unless your switching your plant after week 3 but whats the point its not going to get as big as it could.
That same breeders auto strain is said to be complete in 75-80 days.
That's 11 weeks and what I expect out of most autos fully grown out. 10-14weeks.
This all points to my assumptions above:
autos are advertised as Veg+Flo time
photos are advertised in Flo time only
Hope this helps.
