light?

i just finished my 21 days and i dont know if i do 18/6 or 12/12
i think its 18/6 can someone help and if it is 18/6 for how long untill the 12/12

if you want to go to flowering just go to 12/12. I have heard of people doing 18/6 for a few days then 12/12 but no one really thinks it matters

you might not want to start flowering till your plant is atleast 12-18inches high. rember that your plant will double or even triple in hight.
finshed 21 days of what?

i usually do 18\6 until i got 7-9 blade leaves than 12\12........ clones 24\0 for 10-15 days 18\6 for 10-20 days then 12\12 and thats what i do

wat i mean about im done with 21 days is that the plants are 21 days old since cloned i did about 16 days of 24/0 and now im going to do the 18/6 for a week see how that goes then 12/12 ( im doing 7 black widows under a 1000bulb and 600bulb on the side ) ill see if i put some pics up
