From my experience with raising benthic copepods, both tisbe and californicus tigriporus(hopefully spelled right), I've found that it generally takes about 3wks or so to seed Any significant increase in population. It takes around 2½-3 wks for eggs to become full grown adults and begin to reproduce successive generations. The naupalii will cling to surfaces and seem to be attracted to light, but I think that if you scrape the glass, you'll be ok as long s you gently scrape it down and not use an algae magnet. When first establishing a colony what I like to do I'd raise them in a glass or plastic jar. It is much easier to feed them without using a large amount of feed (I use phyto feastby algagen). I use a 6-8oz container, abd have it ¾ the way full of culture media(saltwater @ 1.020sg) and about 100 or so pods. I add one drop off phyto feast daily and keep it near a sunlit area but out of direct sunlight. Each week I suck out 1/5 of the water and add new water. After 3 weeks, I'll move the bottle or container to my sump or main tank at night and let the little guys venture out to find a new home(after acclimating them to 1.025sg by putting in 2ml tank water in container once every 30 minutes for 2hrs).
After 24 hrs of the culture jar in the main tank, I slowly remove it, inverting it to release any stragglers. I've done this in my refugium and after the first two weeks it seems like nothing is happening. By week 6 I can see them all over the glass.
Hope this trick works for you as well as it has for me. Good luck
