Re: is this a good idea or not?
The chart is per pound of bees. If you are too warm and you may be with the glass, there is going to be early brood and more brood. Will be a large population and extra honey consumed. Don't want too much brood as bees spread out to protect it all and a cold snap can then cause serious losses.
You will need to monitor food reserves and if it works out you'll have a hive with early population build up and likely lots of honey.
Zone 3b. If you always do what you always did, you'll always get what you always got!
