indeed, it'l hold 12 50l rubs, i just got 4 to assemble and house the royals and corns. got room for another 8 now. then il whack a top on it once i figure out what size rubs to house hatchies in as they'l all live on the top. iv set aside 3 of the spaces for hold backs from my normal x bumblebee plan that'l happen next season. just hoping i dont get carried away before then!
