Well said, Meg.
Bit of a bully, our Finman. Pity, really. Sometimes he seems worth listening to.
(And I speak as someone with no bees whatsoever!)
worth listening stupid ideas? Why?
i rear every year about 40 mating nucs. They have 3 normal frames.
I have splitted poly box with table saw to 3 pieces.
It starts with minimum amount of bees, which is one frame covered.
When the queen lays 10 days later, I add one frame of emerging brood. Then the nuc covers 3 frames and the queen is able to lay them full.
When I take some queen away, I join the nest to another. I just pile them, and then the hive has 6 frames bees and brood. When those brood emerge, I have full box of bees.
In autumn I join the rest mating nucs to each other or strenghten week colonies.
Sercet is well insulated polystyrene boxes. The entrance is 2x2 cm. Not a mesh floor.
It is very simple to make strong colonies and nucs for winter, here in cold county in a short summer.
You just accept the limits and speed how the colony grows. Don't try to fight against them.
Summer is too short to it. I start nuc rearing after 15,6, when main hives are strong.
A free advice: Don't ventilate too much your small colonies and don't keep empty space in them.
If you get 2 small swarms, join them to get at least one full box. You may support a swarm too with brood frame.
