what is the shortest veg time

Ok a quick question.... what is the shortest veg time I can put my indica (millenium bud 23 days from seed right now) through before I can put it into flowering. I'm going SCROG EBB & FLO

thanks

i have heard of immediate, but you sacrafice yield doing that. i did a 5 week soil on 6 plants and ended with some decent bushes

I'M in rockwool and on some sites i read people doing 1 month , I'm thinging of trying it

if you have a hydro system, they grow much quicker than soil. like i said with mine though. 5 weeks, topped them at about 3.5 weeks and ended up with a lollipop type thing with about 6 or 7 branches per plant....and pretty huge colas for only being under 250hps

well i topped them today @ 23 days old so I guess from here I,ll see how they do
