@SaintAliasKnife he is saying as little as 5 min of far red light should work.
I feel 15 min will give a bit of a buffer to things.
I was wrong about 14 hrs being his go to.
Quote from him:
**My go to is 13.5/10.5, haven’t had a strain that didn’t like it.
- It made a noticeable gain for me, 13.5/10.5 gives you 12.5% more energy into the plant over 12/12.*
