12 12 from seed does not effect potency at all , the plants still flower for the same amount of time and when they do start flowering they are mature .only thing that is different is the yield , obviousley the more you veg a plant the more bud sites etc they will have .
'sativa high' is correct, 12/12 from seed produces buds of the same quality as conventionally grown buds. He is also correct about lower yield. I have grown under big HPS lamps in my time, with 6 week veg periods and I know that
quality is not in any way reduced. I also stand by the fact that CFL grown buds also compare favourably with HPS grown buds if you do it right. I grow 12/12 from seed for 2 main reasons:
1. It's the only way I can have total control over the size of my plants and fit 6 in my small space.
2. I can grow perpetual harvest style in a
single cab.
Remember, these plants still take 12 weeks to finish! You are NOT cutting down time, just reducing stretch considerably. They take on average 18 to 21 days to show first pistils and I like to think of that as a 'veg' period, they are growing and putting down roots but not flowering. My strains therefore get 3 weeks before they will show pistils (they are all feminised) and then 9 weeks of flowering, all under the 12/12 cycle. I generally start to tie them down (LST) around 3 weeks and continue to pull them 'down and round' right through flowering to keep them compact and tight. My targets are very simple, I need each plant to produce a solid half OZ dry, and they do. I know growers who can hit a full OZ under 12/12 from seed, by using bigger lamps and bigger pots. My whole point here is achieving a balance between plant size for my space and yield. Over the 12 week cycle I run 6 plants, this gives me my 1oz per month average, often a little bit more. It's 'horses for courses' if you have limited space this is a good solid method of achieving this balance. I smoke every single day from my cab, and have not had to buy weed for many years now
That's all I want from it. The other bonus is I get to smoke many strains, often every couple of weeks I get to smoke something different.
I hope this helps. I will try to get some shots of the Ceramic Metal Halide and its small ballast next as they are perfect for small cab grows
