Summary:
Continued conservative watering. Added approximately quarter cup to water box, as evaporation has caused it to deplete. This will maintain nice humidity for the plants. Still no results on the tomato seeds. I will let the following crew know, and if by next week there is no sprouts we will continue experimentation in an attempt to rule out that the seeds were too old or over exposed to extreme heat.
Radish sprouts not showing measureable growth. One sprout is not doing well even in the new pots with the gravel in the bottom. Fingers crossed anxiously waiting.
