The Fastbuds are way ahead of the WOS NLxBig Bud phenos. I’ve increased the light intensity 10% a day up to full power on day 35. Day 31 Wedding Cheesecake pictured. Also started carboload and big bud on the faster flowering phenos and voodoo juice for 10 more days
Very nice.
Bro, they seedlings. 25% will do. You don't need to be wasting energy.
You'll get away with 50% right up until pre flower with the light you have.
Good luck.
