How make seed\plant?

For making it grow, you need to use a tick rate event that turns a block into another stage of it (increase the tick rate or it will be very fast)
If it breaks, try to make a new farmland block and make that for placing your crop you need an item with a right click event that checks if there is your new farmland, consumes the item and makes the block. Use block mod type for making the crops and not plants or they 'll break.
Sorry for bad explanation

To make a growable plant, you need a series of textures of the crop growing from the initial to the last stage. After creating the stages, you should go to all of the stages except the last stage and change the tick rate to 400 (That's the normal value in Vanilla MC, you don't have to do it to this value, it's up to you). After that go to the event about the tick rate to make it so that the block will remove itself and puts down the next stage. (For example: If you were on stage 1 you put 'Remove Block' first, then 'Add Block' and the block you choose is stage 2)

Once it is working properly, you can decide what each stage will drop. They can either have nothing, the seed, partial amounts of the crop or the whole crop. Now for the seed. Make the seed, simple enough, right? When that is done you go to the events and go to when right-click on block and make it add a block, but you need to set the coordinate Y (or J, the arrow that is facing up) and put j + 1 or the block you right-click will delete.

I think that's it. See how it goes :)

Is there a way to make a plant with 3 phases that has a tick rate value higher than 1000 ticks (Which is less than a minute and makes my plant grow like instantly)? If you could offer help, I would be very grateful
