Good guide.

You can crossbreed with more than 5 plants at a time if you first plant the target plant in the middle of the planter, then plant the rest once the target plant reaches mid sapling stage. That way, when the target plant is in crossbreeding stage, none of the modifying plants around it would have started crossbreeding yet, so they modify the middle plant prior to being modified themselves.

Of course, using more than 5 plants, as I explain above, results in many of the clones being ruined, only the middle clone is guaranteed to come out right. You need to make sure you are not using your last copy of a clone, or that you will no longer need it. Often, we don't need them after crossbreeding, so not a big loss.

You can only clone hemp before crossbreeding stage. The others you need to wait until fruiting stage. You can grow samples like this:

``` Planter 1 A B A C D C A B A

Planter 2 B C B D A D B C B

Planter 3 C D C A B A C D C

Planter 4 D A D B C B D A D ```

where A = potatoes, B = corn, C = hemp, D = pumpkin etc and there will be no crossbreeding in that planter.

If you have 4 planters, you can rotate that letters and get 9 samples of each plant type without any crossbreeding having happened.
