I currently have one 8 frame Flow-hive n 2 more 8 frame non flow-hives. I also have 3 10 frame Langstroth hives. All my hive brood n first supers are deeps for better survive honey supply in our northern wet climate near Seattle.
My wife bought me a new 7 frame Flow-Super to try on one of my Langstroth hives this season. I've been able to add my 6 frame Flow-super to a real enthusiastic colony of bees in my Flow this Spring. It's been on for about two weeks already n the girls are busy (looking in the end window) on the three more center Flow-frames.
That should catch you up on our progress here in the Foothill country east of Puget Sound.
