I think that was me that posted the 24/7 on the new clones. I am definitely not the expert. This is my first year cloning but I am having great success. I also have very cheapy stuff. My large box approx 3x3x5 used to be a cabinet at some business and they were tossing it. I added a little paneling on the sides, 4 double 4 foot flourides wired onto a piece of wood, chains and nails to move the lights up and down via little holes in the top and the most technical thing is two muffin fans. One on each side with one blowing in and the other blowing out. A very minimal investment.

I just moved most of my clone mothers out of the big box and threw them under a flood light with a timer so they have just 7 hours of dark.

My little box 14" x 12" x 4' with one 4 foot double flouride is where I have been starting my clones.

In my big box I run 18/6, in the little box I run 24 hrs 7 days a week with one 25 W flouride.

I have about 95% success rate. Hope this helps.
