When doing seeds i stay with a 12/12 still takes them 3-4 weeks to go into flowering. I suspect the same thing will happen with clones, you can place them in flowering scheldule but they will have to go thru a veg state for a while before they flower I do believe.
I threw a just rooted clone still in the rapid rooter into my flower box which is the first pic then the second pic is about 3 weeks later so i think this may be what you mean.
TY Mc Puffin. That looks pretty good gor 3 weeks. Would like to see it in about 5 or more. Looks like it will make a good bud. I am gonna go ahead and flower mine too. I need to get a camera so I can post pictures too. TX Man.
I think it would have made a nice little bud but the way i had it set up was just the rapid rooter and i got stuck at work late one day and wasn't able to water it and she ended up drying out so if you are gonna do it this way i would recommend putting it into soil that way it will hold the moisture better.
