Changing the colour of the buds?

Hi, i am new to this forum and to growing itself.

I am curious to know how do you change the colour of the buds? I have read up that colour change can be done by dropping the temperature significantly during the last few weeks to about 10 degrees celsius or a something like that (correct me if im wrong), if this is right how are you meant to do this?

All advise and input is appreciated and thank you in advance

Good genetics and the right growing enviorment is what you need. Ice cold water will turn but cause defs of phos. I read some were you could try food coloring but certa in color harm the plants by blocking the something been several years since reading but I believe blue will cause no harm. But don't go fuckering with all that just continue.pheno hunting.until you find what you want and start there

Oh yea what I would suggest first is grow so you get your foot in the door without spending on genetics. So you can learn to grow and once.you can grow with no major problems them start chasing color bag appeal etc

Thank you for the link and the input guys, but if i was to do this in the future once i have my foot in the door how would you be able to lower the temp without compromising the humidity levels?
