the end of there 3rd week after sprouting the plant has finished using up all the nutrients within the seed from sprouting to that point from then on u can begin a feeding regime always starting out at least 1/2 to 1/3rd strength the recomended dosage on the nutrients instructions after that it should be good anytime to switch off secondary growth is a good indicater of vegitative growth taking off so keep an eye out once they begin veging they take off good luck
1/4 recommended dose
Hi Mean,
Are you asking when you can switch to a MEtal Halide or some other HID?
You can use the HID right away. Just becareful you don't torch your seedling.
Use your CFL's 24 hours a day and introduce your HID 1 hour(on) a day.. and each day the seedling gets older leave the HID on an addtitional hour... by the 2nd week you should be able to leave the HID on 24 hours....
: )

Whats up man i think im just going to pase my self out on this one this is the farthest i have got plants. i think im going to let them get farly big before the switch maybe after the 3rd week. You think that much of a light change that far from seedling stage will kill it or make it grow outta control :rasta: let me know what you think ANYONE or you knowm.
They will get bigger faster with the HID light. I start my seedling under HID light. I just have the light a long ways above them until they get theyre second full set of leaves. Then I bring the light down to about 18" from the tops and the veg is on. LOL
I wouldn't let them veg under CFL's if you have an HID available.
Laterz
pssst knowm... i love you
