When to switch to 12-12?


#1

A question from a fellow grower:

I started my seedling November 1st. I have a 400w lighting system because it’s only one feminized plant. I decided to do a 24hr vegetation cycle until flowering. My question is. How many weeks should I go until switching to 12-12. Or is it a visual aspect of the process? Thank you.

It is up to you. 4-8 weeks in the normal window. For bigger plants go for 8 weeks.

It is not advisable to use a 24/0 photo period for grow cycle of feminized seeds. Photo period, temps, and humidity play a big part in maintaining the female quality of that seed.

There is a great excerpt from “Henk” of Dutch Passion seeds in J. Cervantes Indoor grow bible. It explains this very same thing.
