what I did is turn on for 1 hr in morning , 1 hr around lunch , 1 hr before lights off for 3 days .. then I’ll do couple hours in morning and couple hours before lights off for a few day s , then she on for 12/12 while keeping an eye on things , so if she starts acting weird or show stress from the UV light , start the process all over till she is use to it ….right now the plant is 2-1/2 ‘ from the light … and of course this is dependent from strain to strain …let me know how it goes for you ..Right on! I’ll start easing them into it. Looks good.
