Direwolf20 is currently playing (and YTing) a Regrowth series... This is his method:
Note: This is just to upgrade seeds to 10/10/10.
Since weeds are disabled in the pack, you can improve your stock from a single seed. Start with 1 seed and set a row of double crop sticks off to one side. Using more sides gets more (lower value) seeds but in my opinion wastes 1 crop stick per block. If you want you can make right angle turns to extend the length of the row, depending on your irrigation system. I use a 9x9 plot of the appropriate growing media with 1 water in dead center to irrigate the entire patch, running the following pattern:
Code:
[S] = Starting seed
[*] = Crop stick pair
[W] = water
[ ] = Space
[S][ ][S][ ][S][ ][S][ ][S]
[*][ ][*][ ][*][ ][*][ ][*]
[*][ ][*][ ][*][ ][*][ ][*]
[*][ ][*][ ][*][ ][*][ ][*]
[ ][ ][ ][ ][W][ ][ ][ ][ ]
[ ][*][ ][*][ ][*][ ][*][ ]
[ ][*][ ][*][ ][*][ ][*][ ]
[ ][*][ ][*]{ ][*][ ][*][ ]
[ ][S][ ][S][ ][S][ ][S][ ]
This allows for 9 different seeds to progress simultaneously,
When the plants appear in the position closest to the water I pull and analyze them. If they are 10/10/10 I check the others and transplant the final seeds to their permanent area. If they aren't quite ready I remove all the plants and plant the new seed where the original started and run the process again.
Any non-optimal seeds are discarded except for wheat seeds, which are used in Botannia. I also like to generate and keep a stack of the optimal seeds in case I want to expand a crop.
I keep a smaller area for crossbreeding.
