....advise that I try the terrariam heater in January for faster spring build up or will my hive build up too quickly and use up their stores??
Hive cannot develope it it does not have pollen. And it never developes too quickly. I do not know what is you landscape in January, end or beginning?
When snow cover is away and bees can fly out, you may give pollen patty to bees. It accelerates brood raising.
If you have too much capped frames in the hive, you must take extra off so queen has room to lay eggs. When hive consume it's winter food, you ad one capped frame to them.
It is enough if one box hive has 2 full frames food.
If they does not consume frames, you may give food to another nuc.
When you give capped food to hive and another frames are foundations, bees unpack capped food, queen lay eggs into combs and bees use sugar to build foundations. - somehow like this it goes.
