damn bro mine didnt look like that when i tried 12/12 from seed. i have different lights for my plants i norm. put my plants under 250 watt mogul cfl for my veg. and 250 watt hps for my flower. but i figured since i was tryin 12/12 from seed it would be in flower the whole time so i didnt bother with the 6500k spectrum i just put my hps over it. mybe that was to much for it!! hell mybe i should give it one more shot!! peace outI think conditions play a big part along with the light that is used. Some prefer to veg for 2 weeks under florescent first before you go to 12/12. I think it helps with the F to M ratio a bit better. Check out this forum on it. Some great information and successful grows as well.

First time trying it myself. Here are the first ones I started. Two weeks old when I posted this.
i dont have the standard cfl or floro this is what cfl i useI have noticed that a few of them are getting a bit too hot from the 1000hps at first sign of water leaves also. If you set them under floros just to get them going a bit it wouldn't hurt. Also if you put them under 4 bulbs, floro within one inch of the bulbs for one month, I will GUARANTEE female pre flowers 90% of the time. I am getting 100% with this method, but saying 90% just to be safe. 24/0 for one month under floros first, with them almost touching the bulbs. You'll have to move the light daily but who cares when you have a pulley system.
