i cant speak for roseman, as im not sure he is still active on this site, but heres my .02:
growing indoors, a veg cycle is not always required nor desirable in certain situations.
imho, 24 hours of light for 2 weeks is all you really need unless your trying to grow 4-6 foot trees.
recently, ive experimented with 12/12 from seedlings (10 days under 24/7 t5's then switched to 12/12), and im pleasantly surprised with the results, but my op is a SOG... so im not shooting for big bushes.
by eliminating the veg cycle altogether, it shortens the lengths of time between harvests
remember that alot of strains will double in height when you switch from veg to flower.... this 'stretching' messes up the plans of alot of novices when suddenly there plants are within 6" of there lights only 1 week into flowering. if you give them 24 hours of light to get on there feet for 2-3 weeks, and switch to 12/12, you can get a harvest in as little as 11 weeks
from germination... instead of 2-3 months of veg, then min 8 weeks flowering. yes, you get bigger plants with long veg cycles, but it drastically lengthens the growth cycle. also alot of people have problems with ph during late stage flowering because of nitrate buildup in there growing mediums.... shortening the cycle prevents this from happening! theres lots of advantages, and a few disadvantages to running short veg cycles... its really all a matter of preference
