re-vegetating marijuana??

Im just about at harvest time and i cant find too much info on making your plant revegetate. I heard the yields were cute down 75%? is this true?

Also my buddy plant started out doors and moved it indoors but it looks like it started to flower with alot of white hairs, some starting to turn amber on top.. but he has it in 24 hour light now. Good or bad idea??

the strain doesnt seem too amazing so would i just be better off starting from scratch again cause i bought some BB,BG,NL and WW seeds??? thanks

It is usually not wise to bring outdoor plants to indoors. You will be inheriting the plethora of pests and possible diseases of fungal or bacteial in nature into a controlled environment.

I would start from scratch with the new seeds you bought. As for your Buddy , I started my first grow out side and moved it into my DWC and lost most of my plants . I have to agree with calicat on this one .
Good luck and keep growing

From what ive read you can get the same yield out of a revegged plant. Leave some leaves and lower buds after harvest, give it 24hrs of light and nitrogen
