No, i don't agree with certain notes you made here.Finola starts to flower not after a certain internodes, but after 20-30 days.I've grown Finola last year like i have grown a family member in the 90s named Red dawn which also started to flower after 20-30 days.Finola is imo also photoperiod neutral.

I know we have a friendly disagreement here but, I've grown finola for 6 years now. Some start flowering as soon as 12 days of age, some might take up to 40 days without signs of sexing but regardless of the phenotype, any finola will flower within 2 weeks if started in 12/12.
