When the gamerule randomTickSpeed is set to a high number (e.g. 50000), crops such as sugarcane and cacti grow so quickly that when a the middle block of a 3-block tall crop is broken, the top block (which would break in the next tick) is able to grow a new block above it. Since this suspended plant is not 3 blocks tall anymore, it can keep growing (potentially up to the height limit, as shown in one of the videos), all while the bottom blocks of the floating plants keep breaking every tick. In rare cases (such as the one shown in one of the videos), these crops grow so quickly that the broken block is replaced before the top block can be destroyed. This can occur simultaneously with the previous effect, allowing for 4-block tall grown plants.
This could theoretically occur when the tick speed is not high, but it would be hard to reproduce.
How to Reproduce:
- Set the gamerule randomTickSpeed to a high number (>40000).
- Plant a cactus or sugarcane.
- Keep breaking the middle block of the plant until a cascade effect occurs.
