I love being foundationless.
I started beekeeping this year and have never used foundation so no transitioning for me ;) but from what I can see:
1) foundationless is way easier on a beekeeper. Its cake to just throw popsicle sticks in the groove and assemble and throw the super together. No messing with foundation or cutting it to size
2) the bees figure it out real fast. I threw a 5 frame nuc into a deep with 5 foundationless frames and they filled them all in under two weeks. Its taken them about a month to almost fill the second deep with was all foundationless frames (I did pull one filled frame from the bottom deep to put in there so they had something to climb). I'm putting on a super tommorrow cause they need more to do ;)
3) there is research saying natural comb may help keep mites and moths and all that away. I figure why not try it, even if it helps just a little, its worth it.
4) its beautiful, natural comb is really, really beautiful. When compared to the 5 frames my bees came on, the natural comb just looks so much prettier. :)
5) I haven't had a honey harvest yet, but I would assume its easier to harvest comb honey when there is no foundation. I can just cut it out and replace empties and my girls will rebuild ;)
6) its getting away from mans modifications on beehives and letting bees do their thing the way God intended
so yeah I'm right there with ya, foundationless rocks!
something I was told when I started and don't see posted here though, is that you really want to make sure your hive is level if you go foundationless.
Ok I'm out ;)
