U dont have to go 12/12 from seed man... Most growers prefer to let their plants stay in veg(18/6), until preflowers show, sex them, discard males, and THEN switch them to flowering(12/12)... All depends on how big u want your plants to end up being... And to me, it just seems more natural, and healthy for development to do it this way... A one month veg time is a tad short, but still ok... Just wont see as much yield, because they never got a chance to build up much structure, or root systems either... But, to each their own... I run two crops a year... I let mine veg out for more like three mo, and then flower from 2-3 months, depending on the strain, and all that... But, because I get PLENTY of yield, it lasts me 6+ months, and I dont HAVE TO run three or more crops a year... All up to personal choice... Alot of folks only ever put them under 12/12, but they NEVER get very big, and I personally htink that they don't get all of the growth time that I believe is necessary for full potential development... But, thatz just me...
