I did a whole lotta thinkin about this one...first was stress...well,they are used to that light,right? so,not stressful,imo
next was deciding how long to kick them on for,and when....I have spent a whole lotta time with these girls,at least 4 hours every day,and I noticed that when the light comes on,30 minutes later they start growing fast,and this spurt continues for a couple of hours...so,30 minutes to wake up,and 30 more to soak up the light for continued growth after lights out...how long I should do this?...My reading tells me they will reenter veg in 2 weeks,so ten days sounded like a good guess,and now I wish I had only ran it for a week,cause my miracle gro babies took off like a rocket,not fully flowering anyway,so it was just veg for them...except for that ten day cycle,they were under 12/12 from seed....both well over 4 feet now,at 5 weeks old....this is all a theory mind ya,and it has did what I wanted so far,which was to grow bigger buds with no hermies,and to use up some of the leftover nitrogen in that extended release soil....the only thing I don't know yet is how long I delayed the harvest...I am hoping for aug 1(the 2nd is my birthday,what a present huh)but I don't know if I will make it or not....still got to fill in a lot
