I ran overhead (inverted jar feeder) syrup for much longer than usual going into winter, as it was going down so well into an August swarm. When the uptake rate slowed down I swopped over to overhead 'dry' (well, damp) sugar in the same jars - that's also going down well.
As I see it - there's no need to make, or buy extra kit. With pierced lids, run syrup. Without the lids, the jars can be used for sugar, candy, fondant or pollen patties. (Even mix 'n' match) 1 to 4 jars, depending on rate of uptake:
Top right hole has a 15mm dia vent installed during a period of very warm weather - now bunged-up as it's turned VERY cold.
