How long would u leave snow white in veg before flowering?

i am growing under 1 400w mh and 1 400w hps in a hydroponic system, useing floranova for fert. and finish off with overdrive, my last problem was i didnt relize how much more the plants would grow after the cycle change so they got really strechy. so how long would u guys let this strain go in veg before changeing the cycle? i have lots of head room but REALLY dont want that much stem between buds.

if you want them small and bushy keep the light as low as possible without burning them and also genetics play a part in stretching..Indica's are short and bushy. I havent looked at the snow white but the veg time should not effect the 'Stretchiness'

i was more thinking the size of the plant come harvest time, i only want them 2.5-3ft tall and ill have 10 plants in the set up, the table is 5x3 with room for 15 6inx6in baskets so i also dont want to starve any part of the plant for light

Most plant about double in size when switched to flower so if you want them 3ft tall...switch when they are about 14in...
