Growing Boom Fruit is challenging, as we need to make sure it doesn't blow the whole place up. This means higher costs and the need for stronger walls.
1) Construct Boom Plantation, this needs 10 Boom Fruit & 10 Hellerium. It can be either constructed anew, or on top of an existing Plantation, the latter saves us $80k.
2) When ready, 'Dismantle' it as normal, $50k cost.
3) When fully grown, 'Dismantle' again to harvest (costs $10k). This will net us 100 Boom Fruit and leave behind a standard Plantation.
