I am a little behind on this. Bear with me!

The seeds were planted on The 7th of December, 20 days ago from this post.

they germinated within the week of planting.

The Radishes are under a daylight florescent bulb on a shop light spot light.

I used general miracle grow plant mix.

This is growing in a galvanized steel planter approx 14"x4" (i think) and it has about 3 or more inches of soil.  

I have a 19-30 days listed as harvest time but being day 20 I doubt it will meet that. I think it might be the cold Temps in the basement sometimes dropping into the low 50's.

This post will be updated.
