Out side then inside?

if i have my plans outside and they are around like 8inches tall would it mess them up if i brought them inside and put them under lights?

No ,it would be fine,
i grow outside 6am to 6pm,then bring them in under lights for another 6 hrs so they get the full 18 hrs...
No problems,just give em plenty of light and a fan,and be very punctual..dont be late with bringing em in ,
same time everyday,same light power....sure to be fine!!!

thanks man stay smokin
