gettin the purple the come out..

u I got a question... so I jus started flowering my 4 gdp clones... n I wana get the purple color to show... I kno its in the plants genes... I hear u gota keep the growroom a lil colder than vegging.. about 60-75 degrees I hear... whut do u guys think?? or know how to get the color to show... thnx

I've heard that black lights do that. When you're on your 12/12 flowering cycle have them turn on when the regular lights go out. Just something I heard though so I'm not sure if it's true. Would love to know the answer to this too.

If it's in the genetics it will show near the end of it's life. Lowering temps in the flowering room will work on some plants but GDP will show it's true traits without the low temps. Black lights is just an illusion and once you turn the light off its back to normal.

black lights are not used for any part of growth. the purple should come out towards then end og growing.

ya I knew black lights weren't used for growin... and I heard about the temp thing frm a few people so I needed clarity.. thank u guys for the help...
