Bay Area, California
The 3rd medium has 6-7 build out frames and the hive looks strong and healthy.
Over the next week high temetures are forecast, I was thinking to add the 4th medium early to help the bees with the heat. More space, better air flow. Also worried about swarms.
One the other hand I read that space mangagment is critical and to that point should I not wait one more week till they have 8-10 frames build out?
Adding the poll for fun. And I wanted to try it out.
