I agree with amino and russ...get them on a minimum of 18 hours, but 24 is better. I've found that they do well under a filtered or lower light. Also, make sure you mist them every day; clones need that. Hope this helps.
Is there a reason why you can only give them 14-15 hours of light, as opposed to 18-24 hours?? Consequences is that they will grow slower and won't be as healthy, IMO. Are they only getting natural [sun] or artifical light??
its artificial light. only a 400 water with three plants. (afghan goo, n.y. sour diesel, and orange crush). the reason they only get 14, 15 hours of light is because im not around my house all the time, and my safety freak parents won't let the light be on while they sleep. Thanks for the help any tips are appreciated.
