question about minimum veg time and flowering heights

about 2 years ago, i did my first indoor/outdoor grow (vegged indoor, flowered out). everything went well and i got my first taste of "good genetics"...

so....i recently moved into a new apartment and i have roommates for the first time in a while. although they all know that i smoke bud, i don't know how they would feel about me growing it.

my dealers are coming through with good mids/highs at good prices. however, i do miss growing....and i miss the taste and feel of "designer bud". (most of the bud that my dealer sells me he has no idea what it is...and all pretty generic...probably bagseed)

i still have alot of seeds left over from when i grew last time and i was wondering if its possible to do a "mini-grow". i don't really care that much about yield. all i really want to do is have fun growing again and get a little bit at the end to enjoy. i currently have a few white rhino, aurora indica, ak47, and c99 seeds.

yes...i do know if i don't veg them for a long time...my yield will suck. however, at this point in time i don't really care about wasting seeds (since i have a good bit of them saved up) or getting a big yield. i'd be perfectly happy getting a quarter off each plant so i could have a tackle box filled with different strains ;P

i plan on growing pretty stealth with CFLs since i don't really feel like dealing with HPS or MH at the moment. what would be the shortest veg time i could do before putting the plants into flower? whats the shortest height i could get if i LST?

thanks in advance
