hybrid dendrobium burana
 

It had no good roots... I tried to remove the roots by pulling, but i manage to dmg part if the cane where the roots came from. I repotted the rootless dendrobium in spag moss and water it dyna kln root horme. Is this a good method to make it produce more root?

It may be ok - Dens can be very resilient.

It will not grow new roots until it thinks it's the right time. I don't think the rooting hormone changes this for those orchids that have definite rooting seasons. Until then keep it humid. I know some parts of PR are humid and some parts are not so humid.

its growing keikis but still no roots. I had them stuck in spagh moss and today i dicided to take them out to see id any progress and i saw the keikis!!!!! i replanted them but just over the spagh moss this time. One of the canes is yellowish, is that a bad thing?http://oi67.tinypic.com/nq37s7.jpg

What I can see looks fine. They new growths should turn green in the light. Roots will follow.
