ok guys i need help. iv got a healthy little seedling growing under 18/6 (6500k 18watt x2 CFLs) i know i know... but iv been looking up the 12/12 from seed regimen, and what i would like to know is if i go with 12/12, should i keep the cool whites (6500k's) while its in 12/12 untill i see it start to bud? or should i be using warm whites (2700k) ? From what i know, 6500k is better for veg. and i imagine it wont bud yet lol, so the obvious choice would be 6500k? or no? Because i have only 10 and half weeks to grow this plant, i want to do it as fast as possible and have a harvest in 10 weeks. So would it be wise to keep it under 12/12 with 6500ks or 2700ks? And will 12/12 have a negative effect on the veg stage? Will only 12 hours of light slow down the growth signifigantly? or minor-ly? lol. please help.
If ya check some of my old threads, you can see what I do with CFL's.
I use the 5000k to veg for the first bit, then add some 2700k, and continue with both through flowering.
Last Winter, I did 5 plants in a 2x2 space with the CFL's, rotating them out every 12 hrs, and got over 4 1/2 oz. from an East Coast Sour D that I vegged for 30 days, but a couple Blueberry that I did 12/12 in only 1 gal. pots, I got over 2 oz. each.
As far as your time frame, I did do a little experimenting with hours, and doing an 11/13 will shorten the flower time a little, but the reduction in total yield IS noticeable.
