I'd like to mention that a plants tolerance of going 12\12 from seed varies quite a bit based on strain.
Some want to veg for 3 months before they even show sex regardless of photoperiod.
Others are growing flowers before their veg-room counterparts are even on to their first true set of leaves.
I've had some come out large and in charge, with a single cola weighing anywhere from 7- 30 grams dry.
And with other strains I've had them grow maybe a gram of bud on a skinny wimpy little stem. I have no pictures of these as they were not worth photographing. (in hindsight, i guess i could use a photograph of one right now, so they probably were worth photographing....)
Anyhow, I no longer do it as personally i've found it to be a lot more reliable to grow 12\12 from clone, for a number of reasons. Not the least which is preservation of champion genes. It takes MONTHS AND MONTHS to reveg a plant in late flower and is infinately easier (IMHO) to just veg my plants a while and take backup clones of everything. Every now and then you plant a seed the just has amazing weed, i cant tell you how many times i've lost great potential mothers because i didn't take cuttings. The fact is, even in strains touted as 'stable' there are gonna be good plants and bad plants, personally
But having said that there is nothing wrong with growing 12\12 from seed. You
can grow nice fat honkin buds pretty quickly. Anyone who tells you its not possible is either misinformed, bitter with a failed attempt at doing so, or a liar.
Anyhow, heres a shot of my new ebb and flow table. filled with 3 different phenotypes of my 'house' strain (read, bagseed)
They went straight from the aerocloner into the flowering room about 2 weeks ago.
And here are some Arjan's ultra haze #1 clones in soil, also 12\12 straight from the cloner.
This is one of the strains i've tried that refuses to grow well 12\12 from seed, it grows about 3 inches tall and takes 13 weeks to produce 3 grams.
However, these clones (2 weeks old) have already grown a ton with tight nodal spacing and gigantic sativa leaves.
Which just goes to show how strain dependant 12\12 from seed is, and also reinforces my preference for growing clones rather than seeds.
And heres a budshot (pheno#3 from the aformentioned bagseed) for good measure.
