What you want to do here is record the number of yellow and green seedlings each day
For example, lets say that you take the seeds that were not microwaved and planted in the light group. On day 1, lets say you count 5 yellow and 2 green in said group. Then you would put 5 under "0 seconds", "Ylw", in the day 1 row. same for green, but 2 under "Grn".
Hope this helps!
