does it matter? i have been using clear bin, but the cuttings are rather long. looked for taller bin, but no one has one in clear plastic. i got a blue one that will not let any light in. does it make any difference? i know bin is to keep the moisture in. even the clear one will not provide any significant light to promote much of healthy leaf growth. 

Go to Home Depot right after Christmas.  They will have translucent bins for Christmas Decorations that are about 18 inches high with a hinged lid.  They are usually located in the same area as the outdoor christmas decorations were located. Keep it propped open with a Lego block for air circulation. They are Huge! They are better than anything you can find elsewhere.

If you don't like the lid, take it off and get clear trash bags and tape to the top with one end open to prevent mold.  Or use Saran wrap in sheets across the top.

The colour of the bin should not make difference during the rooting phase. No light is required during this phase. Light will help when the shoots open. Pretty soon they will be high enough to gradually see some light. I use only one bin and keep light over it.
nypd has a good suggestion too.

I use two clear totes of the same size, one is upside down on top of the other and it makes a tight enough seal to create humidity inside the tubs. The entire height of the tub is about 28 inches which is plenty high enough once the cuttings start sprouting leaves.
I have one grow light from home depot pointing downward about 2 inches above the tub and it creates just enough heat to make the humidity in the tub about 75%, it works great for me.

scott, 

i think i'll end up doing that. don't want to keep them in total darkness even tho i'm sure that won't make much difference.

Most people using baggy method with cuttings in moist paper keep the paper in ziploc bags to avoid drying up of mosit paper.

the rooting bin i'm talking about is not for initializing the rooting process. i do my initial rooting in baggie. once i notice the roots, i move the cutting into a cup then move that cup into large bin/storage box to keep the moisture to the cuttings. the hinge box works great for most of cuttings in cups. only problem is some of the cuttings are rather thick, long, and have 2-3 nodes. if they are too long, i would cut them. but with 2-3 nodes, i really don't want to. so i'm going to move them into cups as is. so i'm looking for something that's taller then typical 13" high clear boxes. i went to homedepot, lowes and other places. but tallest ones i have seen are 13.5" tall. i think scott's idea of stacking two boxes will work great.. with duck tape to hold them in place. 

Ok that makes better sense to me.  I must have read too fast.
