Buffs

Buffs affect the base-strength of a plant

When a plant is being 'buffed' its base-strength increases every turn maxing out at max-strength When a plant is being 'debuffed' its base-strength decreases every turn without going under min-strength When a plant is not being buffed/debuffed its base-strength moves towards its original base-strength (new variable needed?)

When a plant is in a toxic pool, it gets a buff.
